Product Description:

1.Structure of Cold Rolled Steel Description

With hot rolled steel coils as raw material, after acid pickling to remove oxide skin for cold rolling, the finished product is hard, because of cold work hardening caused by deformation of continuous cold rolling hard roll strength, increase hardness, toughness and plastic index decreased, so the stamping performance will deteriorate, can only be used for simple deformation of the parts.Hard coil can be used as a raw material, hot dip galvanized factory for hot dip galvanizing unit Settings are annealed wire.Hard coil weight generally in June to 13.5 tons, coil diameter is 610 mm. 

2.Main Features of the Cold Rolled Steel

1, higher precision, cold-rolled strip steel thickness difference of no more than 0.01 ~ 0.03 mm.
2, the size is thinner, cold rolling the thin steel strip rolling 0.001 mm;Hot rolling can reach 0.78 mm the thinnest now.
3, the surface quality is superior, cold rolled steel sheet can even produce the mirror surface;While the surface of hot rolled plate tin oxide, such as pitting defects.
4, can manufacture according to customer requirements to adjust its properties such as tensile strength and process performance such as stamping performance, etc.
Cold rolled and hot rolled is two different types of steel rolling technology, as the name implies, is cold rolled copper under the condition of steel at room temperature, the hardness of the steel.Copper is hot rolled steel in high temperature circumstances.

Q:Are steel casings reloadable?
Technically they are reloadable but it's way too much effort and it'll probably cost more to do than its worth. I know you're probably asking this for surp. 7.62x54r right? The steel will have to be fully resized every time and you should only do it 1-2 time max to be safe. Also if your ammo is berdan primed the primers are very hard to find and these are a whole different beast than boxer primed. Short answer is yes but not worth it IMO.

Q:Can i use an acoustic steel string as a steel-guitar?
Musical style speaks volumes while it includes this concern. people who % severe quantity would be unhappy with unamplified nylon string guitars. From my attitude, the common distinction between metallic and nylon is this: metallic strings ring and nylon strings resonate. the quantity produced by employing metallic is frequently plenty greater suitable than nylon yet, to my way of thinking, the sound resonance produced by employing the wood of your guitar is largely masked by employing metallic strings. in case you have a decently made guitar (frequently, around 1000 money and up), the sound interaction between the wood and the strings in a nylon guitar is magical around the completed frequency selection. With a metallic string guitar, the sound produced by employing the vibrating string overpowers the wood resonance in any respect yet low frequencies. in my view, i will take a nylon string guitar any day for the sensitivity gained from the interaction between wood and vibrating string.

Q:Is boron steel harder?
The only thing that affects the hardness of steel is the carbon content. But there are many elements that can make it easier for a steel to achieve its maximum hardness. And Boron is an extremely effective element that increases the hardenability of steel. Adding as little as 0.002% Boron can have a big impact upon quenching of a steel. Boron is usually added when you need the hardness of a heat treated steel part to extend deep below the surface. For example, lets say you had a two identical plain carbon steel parts, but one had boron and the other didnt, and you wanted to heat treat them both After quenching, the surface should be the same on both, and lets say its 55 Rockwell C. In the plain carbon one, the hardness might drop down to 50 at 2mm under the surface, but the boron treated one might not drop to 50 until 4mm under the surface. Now, these numbers were completely made up, and it would depend on the specifics as to what the difference might be.
Q:What is the difference between cold rolled strip and cold rolled steel coil?
Cold rolled steel strip: the width is below 900mm! Cold rolled steel coil: the width is above 1000mm! Materials and purposes are not very different, basically the same!
Q:what type of steel is used to make rail tracks?
in case you have been to soften rail steel down and pour it into ingots, I doubt anybody could examine to locate this is source besides the fact that a experienced metalurgist could comprehend. whilst the steel grew to become into melted you will desire to toss a handful of previous horseshoes in and alter the composition and no you could comprehend. stable luck such as your challenge, i could decide to comprehend the way it seems.
