Q:What are the different methods of heat treatment for steel coils?: There are several methods of heat treatment for steel coils, including annealing, quenching, tempering, normalizing, and stress relieving. Each method involves heating the steel to a specific temperature and then cooling it in a controlled manner to achieve desired properties such as increased hardness, improved strength, or reduced residual stresses. These methods can be tailored based on the specific requirements of the steel and the intended application.

Q:I've heard on some 1911 forums that the slides of Armscor guns are now extruded. What is extruded steel? How is it made? Are they strong (4140carbon steel was used in the process).: Extruded steel is only the steel being run through a die when it is heated, it usually reduces the size of the grain of the steel itself, enhancing toughness. Realistically though, in a handgun, it doesn't matter if the frame is cast or forged, both types will hold up to any amount of abuse, unless you use it as a sledgehammer, and are splitting stones with it, then the forged frame would win. 4140 is more than adequate for a slide/frame. Hell, even mild steel would be adequate as long as you don't mind some dings and scratches, and again, don't use it as a sledgehammer...

Q:I bought a Remington 870 super mag last fall and wanted to to switch to non-tox steel loads. The gun came with a modified rem choke. I know that not all chokes are qualified to handle steel. It doesn't say anywhere on the choke no steel I was just wondering if anyone out there knew for sure that those chokes that the guns come with won't get damaged be steel.: No problem. With steel shot you would use one choke size LARGER. If you want a full choke type pattern ( 70 % in a 30 inch circle at 30 yards ) you use a modified choke. if you want a modified pattern use the improved cylinder. Don't use the full or extra full. This is because when using lead shot it deforms, and fits through the choke, steel shot does not deform, it remains rigid. The first indication of a problem will be a slight bulge in the barrel right behind the choke. Check that once in a while, if you ever have that problem, it is not drastic if caught early. Today's modern shotguns all have been set up for steel shot. The old ones such as Belgium Brownings, are a no go. Funny thing, when we first began importing steel shot, I asked a Browning Tech guy if he thought I could fire steel out of my Belgium Browning. He said not a good idea, however, if you have the Citori or other Japanese made Brownings, no problem. Hummm, my expensive Brownings, no, but Japanese made OK, this is because the Japanese steel was higher quality. Geeeze. I was shocked.

Q:How are steel coils tested for flatness and straightness?: Steel coils are tested for flatness and straightness using various methods such as visual inspection, measurement tools like straightedges or laser devices, and specialized equipment like leveling machines. These tests ensure that the steel coils meet the required standards and are free from any deformities or deviations in their flatness and straightness.

Q:Could someone please explain what happens when steel is heat treated and why these happenings cause the steel to become harder? Please dig down into the micro details of the crystallites but in somewhat laymen's terms. Also describe the processes which achieve these results; if you have the time. Thanks for your time and effort.: Mild steel is a solution of carbon within iron, etc. When the steel is very hot the carbon is well distributed. As the steel is cooled iron crystals form excluding the carbon that will then collect at the boundaries (grain boundaries) between iron crystals. If cooling is rapid at any point in the cool down crystal growth will cease (affecting final grain size and the mix of carbon and iron at the grain boundaries). The ductility or hardness of the resulting steel will be determined by the grain sizes and makeup of the carbon/iron mix between grains. Ductile iron permits 'slabs' of iron to slip past each other within iron crystals and location of carbon atoms may help prevent slip resulting in hardness. Therefore, heat treatment usually consists of 'soaking' the steel at a temperature high enough to dissolve all the carbon uniformly then cooling it down slowly or rapidly to obtain optimum grain size and interstitial carbon between grains to obtain desired properties.

Q:why do you need to heat steel when hardening, molecules etc etc: Heat treatment deforms the crystal micro structure of the Steel. With heat (and cold) treatment the organisation or Diffusion of the micro particles can be manipulated. There is a higher concentration of particles after heat treatment, thus making the micro structure of the steel more dense, and the physical performance of the steel better. Stronger. Hope this helps ! Please like.

Q:What are the different coil handling equipment options available for steel coils?: There are several different coil handling equipment options available for steel coils, depending on the specific needs and requirements of the industry. 1. Coil Cars: Coil cars are used to transport steel coils from one location to another within a facility. They are typically equipped with hydraulic or mechanical lifting mechanisms to safely load and unload the coils onto other equipment or storage racks. 2. Coil Upenders: Coil upenders are used to rotate steel coils from a horizontal to a vertical position, or vice versa. This equipment is essential for loading and unloading coils onto coil cars or other machinery, as well as for storage purposes. Upenders can be operated manually or hydraulically, depending on the weight and size of the coils. 3. Coil Lifters: Coil lifters are designed to safely handle steel coils during lifting and transportation. They are typically equipped with adjustable arms or hooks that securely grip the coil's inner diameter. Coil lifters can be operated using hydraulic, mechanical, or electromagnetic mechanisms, depending on the weight and size of the coils. 4. Coil Turnstiles: Coil turnstiles are used to efficiently store and retrieve steel coils. They are designed to hold multiple coils in a vertical position, allowing for easy access and retrieval. Turnstiles can be rotated manually or automatically, using hydraulic or mechanical systems. 5. Coil Reels: Coil reels are used to unwind steel coils and feed them into processing machinery, such as stamping presses or roll forming machines. They are equipped with adjustable tension controls to ensure a smooth and consistent feed. Coil reels can be operated manually or automatically, depending on the level of automation required. 6. Coil Cradles: Coil cradles are used to support steel coils during storage or transportation. They are designed to evenly distribute the weight of the coil, preventing deformation or damage. Coil cradles can be stationary or equipped with wheels for easy movement. Overall, the different coil handling equipment options available for steel coils provide a range of solutions for efficient and safe handling, storage, and processing of these heavy and valuable materials. The choice of equipment will depend on factors such as coil size, weight, production volume, and specific industry requirements.

Q:I want to know what to my wash stainless fridge door with before applying the stainless steel polish.: I just use a regular spray on kitchen cleaner like 409. Then after I do that to prevent the streaks, just use baby oil. Put a tiny bit on a paper towel and wipe it over the doors. I learned this from online and from a pal that is in the navy. They can't have streaks on anything for navy inspections.

Q:i know that steel helmets werent meant to stop bullets, but i was wondering do they have an value whatsoever for stopping bullets, or is that just yet another thing that hollywood made up(like the omaha beach scene in saving private rian): richard S is right. They were designed to deflect shrapnel more than anything else, but I have seen few cases where a round striking at the right angle was deflected enough to safe the soldier. The new Kevlar helmets perform much better, I have seen them stop an AK 47 round (7.62x39MM) and they will stop most military handgun rounds. shoot safe

Q:What are the main properties of steel coils?: The main properties of steel coils include high strength, durability, resistance to corrosion, and the ability to be shaped and formed into various sizes and dimensions. Steel coils are also known for their excellent heat and electrical conductivity, making them suitable for various industrial applications.
