- Q: Many gerber knives are made out of what gerber calls high Carbon steels and I was wondering if anyone knew exactly what is this mysterious steel.
- A steel knifeblade is like a box full of a million ball bearings. The molecules pile up/line up just like those ball bearings. When it's pure, though, you can easily deform it....just like you can ram your hand down into that box of ball bearings. What happens if you pour a gallon of heated wax over those bearings, though? It fills the gaps between the molecules and solidifies the entire mass into one solid shape. If you smack it then, you'll break your hand. It'll hold its shape *much* better and longer. That's pretty basic but what do you expect at 04:00? ;) Addendum: At one time, in the late 80's to mid 90's, it was 440a...they then switched to 440c on their mass market stuff and 154 on their special runs....late 90's-2005 went to all 440c....today's knives are a mix of 440c and some pricier knives sporting S30V blades. If it's Gerber and it costs less than $40 today, 99% of the time it will be 440c.
- Q: How are steel coils inspected for thickness?
- Steel coils are inspected for thickness using various methods to ensure their quality and compliance with industry standards. One common method is using a non-contact laser measurement system. In this process, a laser beam is directed towards the surface of the steel coil, and the time it takes for the beam to reflect back is measured. By accurately calculating the time taken, the thickness of the steel coil can be determined. Another method involves using ultrasonic technology. Ultrasonic sensors are used to emit high-frequency sound waves that penetrate the coil. These sound waves bounce back differently depending on the thickness of the steel, allowing the sensors to measure the thickness accurately. Additionally, some manufacturers may opt for an eddy current testing method. This technique involves passing an alternating current through a coil, creating a magnetic field. The thickness of the steel coil affects the impedance of the coil, which can be measured. By analyzing the changes in impedance, the thickness of the steel coil can be evaluated. Furthermore, some companies employ a mechanical method called the caliper method. This method involves using a caliper gauge to physically measure the thickness of the steel coil by applying pressure to the coil and reading the measurement on the caliper. Regardless of the method used, it is crucial for steel coils to be inspected for thickness to ensure they meet the required specifications and provide the desired performance in various applications.
- 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 used in the production of steel tanks?
- Steel tanks rely on steel coils as a vital element in their production. These coils, typically made from top-notch steel, act as the primary raw material for manufacturing steel tanks. The initial step involves unrolling and flattening the steel coils, which are usually supplied in a coiled form from the steel mills. Once unrolled, the coils are then cut into specific lengths and widths, depending on the desired dimensions of the steel tank. These cut pieces are molded and shaped into various tank components, including the cylindrical body, top and bottom ends, and additional fittings or accessories. The strength and durability of the tank heavily depend on the steel coils, ensuring its ability to withstand the demands of its intended use. The quality of the steel used in the coils is pivotal as it determines the tank's resistance to corrosion, pressure, and external forces. Additionally, employing steel coils enables efficient and cost-effective manufacturing of steel tanks. The standardized nature of the coils ensures consistent quality and dimensions, streamlining the production process. Precise cutting of the coils also minimizes waste and maximizes material utilization. Furthermore, steel coils offer design flexibility and customization options. They are easily formed and welded into intricate shapes, accommodating tanks of varying sizes, capacities, and configurations. This versatility makes steel coils the ideal choice for producing tanks across diverse sectors, including industrial, commercial, and residential applications. In conclusion, steel coils play a critical role in steel tank production. They provide the necessary raw material for manufacturing different tank components, guaranteeing strength, durability, and customization. By utilizing steel coils, manufacturers can efficiently produce high-quality tanks that meet the specific requirements of various industries.
- Q: what is the refining process doing to raw materials in steel
- As Mr. Perfessor says, refining raw steel involves a lot of purifications of the raw steel; and to expand a bit, these refining processes also add corrosion-resistances to certain graded steels, and durability factors, when heat-tempering processes are used. All of these refining processes, and coating processes help steel products last when exposed to moistures, salts, and other corrosive conditions that steel can be exposed to, whether the steel is in open-air/water/space, embedded in concretes and other masonry products, or part of a protective barrier system in power plants, engines, etc. Hope this also helps; the eggster.
