Cold Rolled Steel Is Also Widely Used Jul 25, 2017


Cold rolled steel: its strength is high, but toughness, poor solderability, relatively hard, crisp, bright surface.

Cold rolled steel refers to the cold rolling method and produced a variety of cold rolled steel.

The difference between cold rolled and hot rolled steel is not in the smelting process, but in the rolling temperature, or the rolling temperature. Cold Rolled Steel The finish rolling temperature is lower than the recrystallization temperature of the steel to become cold rolled steel.

Cold rolled steel surface bright, good quality, can be directly used to process finished products, the application is also very wide. But it requires the rolling mill power, Cold Rolled Steel rolling efficiency is low, and the rolling process in order to eliminate the hardening of the process but also for intermediate annealing, the higher the cost.

Cold rolling is often used to roll sheets, strips and pipes.

Cold rolled steel and stainless steel is the difference between cold-rolled steel is a steel, Cold Rolled Steel stainless steel is a class of steel.

1, cold-rolled steel is a kind of steel: cold-rolled steel is cold rolled steel, so cold-rolled steel relative to stainless steel welding performance is relatively poor, Cold Rolled Steel the surface is relatively brittle, hard, not suitable for processing, in general, cold-rolled steel To the customer before the first request through the annealing, pickling and surface leveling steps.

2, stainless steel is a kind of steel: stainless steel is added to the Cr, Ni and other elements of the alloy steel, stainless steel, also known as stainless steel acid, Cold Rolled Steel because the stainless steel resistance to air, water and other weak corrosive media and acid and other corrosive media corrosion Steel, corrosion resistance This performance is much better than cold rolled steel.

Cold rolled steel and stainless steel thickness difference is quite large, the common cold-rolled steel maximum thickness of 8mm, while the stainless steel is not limited to the provisions of the thickness; cold-rolled steel is mainly through the hot rolled coil as raw material, each volume can To 13.5 tons, while the stainless steel raw materials are not limited to steel, as well as chromium, molybdenum and other categories are metal materials.

Summary: cold-rolled steel is a kind of steel, said white cold-rolled steel is cold-rolled steel; stainless steel is a class of steel, this category is divided into many kinds, such as austenitic stainless steel, ferritic stainless steel; Cold-rolled steel is a target to buy, cold-rolled steel on a material, and stainless steel is required according to their own needs to buy different materials of stainless steel.
