FAQ

1. Do you have QC team?
Yeah, sure, our QC team is very important, they will keep the quality control for our products.for quality inspection every day.

Q: I heard on some shows that you can carbonise steel by heating it red hot then dropping it in black oil. i cant find this no where online, and the process for commercial carbon steel is totally different. can you really carbonise regular steel by heating it to red hot then dropping it in regular black oil. i saw it on mythbusters once. when the made carbon steel hammers to test if 2 hammers smashed together will shatter: Carburized steel is not the same thing as carbon steel. All steel has carbon in it, but carbon steel is defined as Steel is considered to be carbon steel when no minimum content is specified or required for chromium, cobalt, molybdenum, nickel, niobium, titanium, tungsten, vanadium or zirconium, or any other element to be added to obtain a desired alloying effect; when the specified minimum for copper does not exceed 1.04 percent; or when the maximum content specified for any of the following elements does not exceed the percentages noted: manganese 1.65, silicon 0.60, copper 0.60. Carburizing is a surface treatment. Dropping hot steel in oil is oil quenching. It might get a little carbon in the surface, but oil quenching is mainly used as a slightly slower quenching process than water quenching, not for carburizing. Once it starts cooling down the carbon won't diffuse in. Quenching is used to change the hardness. The simplest way to carburize steel is to pack charcoal around it and heat it to 900 C or so. Industrial processes use a gas like carbon monoxide, but that's mostly just for easier process control.

Q: How are steel coils inspected for paint adhesion using adhesion testers?: Paint adhesion on steel coils is systematically and rigorously inspected using adhesion testers. These testers are specifically designed devices for assessing the bond strength between the paint and the underlying steel surface. To begin the inspection process, representative samples are selected from the steel coils. These samples are typically cut into smaller sections to ensure they are free from defects or surface irregularities that could impact the adhesion test results. Once the samples are prepared, the adhesion testers are utilized to measure the force needed to detach the paint coating from the steel surface. The most commonly used adhesion tester is the cross-cut adhesion tester. It consists of a set of blades arranged in a grid pattern, which are employed to create cuts through the paint coating, forming a grid of squares or rectangles down to the steel surface. After the cuts are made, a specialized tape is applied to the grid area and pressed firmly onto the surface. The tape is then rapidly pulled off at a 90-degree angle to the surface, and the force required for the paint coating's removal from the steel is measured and recorded. The results of the adhesion test are evaluated based on predetermined standards or specifications. These standards typically define the minimum acceptable adhesion strength for the specific application or industry. If the measured adhesion strength falls below the specified threshold, it indicates poor paint adhesion, which could result in issues like paint delamination or corrosion. Along with the cross-cut adhesion tester, other adhesion testing methods may also be utilized, such as the pull-off adhesion tester. This method involves a hydraulic or mechanical device applying a tensile force to a small circular or dolly-shaped test area. The force required to pull off the dolly is measured and used to assess the paint adhesion. In summary, the use of adhesion testers ensures a thorough inspection of paint adhesion on steel coils. This process helps in early identification of potential adhesion issues, enabling appropriate remedial measures to be taken to ensure the durability and performance of the paint coating.

Q: How are steel coils unloaded from a truck?: Steel coils are typically unloaded from a truck using a combination of heavy-duty forklifts, cranes, and specialized equipment. The coils are carefully lifted and positioned onto the ground or a designated storage area, ensuring proper safety measures and precautions are followed to prevent any damage or accidents during the unloading process.

Q: What are the common handling defects in steel coils?: During the transportation and storage of steel coils, various handling defects can arise, impacting the coils' quality and integrity and potentially leading to future problems. Some of the most frequently encountered handling defects in steel coils are as follows: 1. Damage to the edges: This defect occurs when the coil's edges are bumped or scraped, resulting in dents, scratches, or tears. Such damage weakens the coil's structural integrity, making it more susceptible to further harm. 2. Core damage: The core of a steel coil plays a crucial role in maintaining its shape and stability. However, mishandling can crush or deform the core, leading to coil collapse or distortion. 3. Coil slippage: Inadequate strapping or stacking of coils can cause them to shift or slide during transportation. This can result in coil slippage, causing misalignment, damage to the outer layers, or even complete coil failure. 4. Abrasion: Steel coils can experience abrasion if they come into contact with rough surfaces or other objects during handling. This can lead to the wearing off of the coil's protective coating or paint, exposing the steel to potential corrosion. 5. Moisture damage: Steel coils are susceptible to moisture damage, particularly if they are not properly sealed or protected. Exposure to moisture can lead to rust formation, compromising the coil's structural integrity and overall quality. 6. Overloading: Exceeding weight limits and improper stacking of steel coils in trucks or storage areas can exert excessive pressure and stress on the coils, resulting in deformation, bending, or even coil collapse. Adhering to weight limits and proper stacking procedures is crucial to prevent overloading. 7. Improper lifting: When lifting steel coils, it is important to use suitable lifting equipment and techniques. Failure to do so can cause coil damage, such as distortion or bending, and can also pose risks of injury to workers. To mitigate these handling defects, it is vital to adhere to proper handling and storage procedures for steel coils. This includes using appropriate lifting equipment, securing coils during transportation, avoiding overloading, and ensuring adequate protection against moisture and abrasion. Regular inspections and maintenance are also important for identifying and addressing any potential defects or issues before they worsen.

Q: What is the standard thickness of steel coils?: The standard thickness of steel coils can vary depending on the specific application and industry requirements. However, in general, steel coils are typically available in a range of thicknesses between 0.5mm to 10mm. The desired thickness of a steel coil is determined by factors such as the intended use, structural requirements, and manufacturing processes. Thicker steel coils are often used for heavy-duty applications that require greater strength and durability, while thinner coils are suitable for lighter applications where flexibility and weight reduction are important. It is important to consult industry standards and specific project requirements to determine the appropriate thickness for steel coils in any given application.

Q: should I shoot Herters .308 steel cased ammo in my Remington 7400.and why shouldn't I?: Kudos to NXile for his/her post. Ironically, I recently posted a similar answer in this forum and got many thumbs down. The problem with the non-expansion of steel cased ammo is not limited to the blow-back and soot build-up inside the action. The other problem is that your Remington 7400 was engineered at the Remington factory as a sporting firearm that uses brass cased sporting ammunition. When you switch to the steel cased ammo, the casing doesn't have a chance to grab at the walls of the chamber to slow it down. The result is heavier recoil on the action of the gun. Over time, you will break something. Also, I don't like the idea of steel rubbing against steel inside the chamber area of a gun. I know sure sure I won't use steel cleaning rods or brushes to clean the barrel of a rifle. So why would I want to chance shooting steel cased ammo? The only stuff I will shoot steel cased ammo out of are the junky SKS and AK style rifles that I don't care about. Anything with real value...and I only use brass ammo with non-corrosive priming.

Q: I was watching a documentary on the samurai vs the European knight. It said that the when Japan was being invaded by the (cant remember) they needed a new weapon. The enemies armor made iron swords useless. While steel swords broke when in combat. So to combat this the Japanese made a hybrid sword. They used a special mold that made the swords back iron while the part that makes contact with the enemy was steel. Also the sword was curved so it increased its armor and cutting power. This revolutionary design made the the sword stronger. The iron back made it not break while the steel edge made it cut through the enemies armor. I want to know how iron is stronger than steel, and how steel can cut better than iron.: This Site Might Help You. RE: Why is iron stronger than steel?
