Cold Rolled Steel Is Widely Used Jun 02, 2017

Cold rolled steel is at room temperature, after cold drawing, cold bending, cold drawing and other cold processing steel or steel processing into various types of steel. The advantages are fast forming, high yield, and no damage to the coating, can be made into a variety of cross-section form to meet the needs of the use of conditions; cold rolling can produce a large plastic deformation of steel, thereby increasing the yield of steel point.

Common cold rolled steel maximum thickness of 8mm, are generally hot rolled coil as raw materials, Cold Rolled Steel to produce a beautiful and easy to use cold rolling dry, each volume can reach 13.5 tons it.

Cold rolled steel is hot rolled coil as raw material, at room temperature in the recrystallization temperature below the rolling, including the plate and volume, many domestic steel mills such as Baosteel, Wuhan Iron and Steel, Anshan Iron and Steel can produce. Cold Rolled Steel Which is called the delivery of steel plate, also known as box or plate; length is very long, called the delivery of steel called steel, also known as reel.

General cold-rolled steel: refers to the type of carbon steel rolled into the plate products (usually rolled into a roll), there are other bar, wire and so on.

Stainless steel refers to the addition of Cr, Ni and other elements of the alloy steel, Cold Rolled Steel which represents 304 stainless steel, stainless steel also distinguish between plates, bars, profiles, wire and so on.

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

The difference between cold rolled and hot rolled steel is not in the smelting process, Cold Rolled Steel but in the rolling temperature, or the rolling temperature. The finish rolling temperature is lower than the recrystallization temperature of the steel to become cold rolled steel. Hot rolled steel is easy to roll, steel rolling efficiency is high, but hot rolling conditions, steel oxidation, the product surface is dark gray. Cold rolled steel requires high rolling mill power, rolling efficiency is low, and the rolling process in order to eliminate the work hardening also intermediate annealing, so the cost is higher, but the cold-rolled steel surface bright, good quality, can be directly used to process Finished, so cold rolled steel plate is widely used.

Summary: cold-rolled steel is a kind of steel, said white cold-rolled steel is cold-rolled steel; 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.
