Cold Rolled Stainless Steel Coil Hs Code-manufacture,factory,supplier from China

The difference between cold-rolled steel and hot-rolled steel is not in the smelting process, but in the rolling temperature, or the end temperature of rolling. When the final rolling temperature is lower than the recrystallization temperature of the steel, it is called cold rolled steel. Hot-rolled steel is easy to roll and has high rolling efficiency, but under hot-rolled conditions, the steel is oxidized, and the surface of the product is gray and dark.

Stainless steel rolls in accordance with the method of classification can be divided into cold rolling and hot rolling two, if it is in accordance with the structural characteristics of steel classification, can be divided into 4 categories, respectively, austenitic stainless steel, ferritic stainless steel, martensitic stainless steel and precipitation hardening stainless steel.Cold rolled stainless steel coil in order to ensure its yield strength, tensile strength, elongation and hardness and other mechanical properties, steel coil in the production of the need to undergo annealing and solut

Stainless steel is initially produced in slabs, which are then put through a conversion process using a Z mill, which converts the slab into coil prior to further rolling. These wide coils are typically made at around 1250mm (sometimes a little wider) and are known as 'mill edge coils'.These wide coils are further processed using a range of manufacturing techniques such as slitting, where the wide coil is slit into a multitude of strands; this is where much of the confusion around the terminology comes in.

Stainless steel is widely used in petrochemical, atomic energy, light industry, textile, food, household equipment and other fields because of its excellent corrosion resistance, formability, compatibility and toughness in a very wide temperature range.

Chrome steel is bendy and stylish . it’s the preferential choice for a few of the surrounded programs and industries.The fabrication and forming approaches are fundamentals which will make stainless-steel clean for utility. hot rolling and cold rolling are the forming strategies that offer a finish to the stainless-steel surface.Stainless steel features are optimized through the use of warm rolling and bloodless rolling. the current rolling and cold rolling can improve mechanical characteristics significantly without altering its chemical composition.

From the analysis of stainless steel coil application industry, the automotive industry is currently the fastest developing stainless steel coil application field.In the past decade, consumption of stainless steel coil plates for cars has risen from an average of 10kg to 30kg in Japan and more than 40kg in the US.Bus, subway, high-speed railway vehicles and other public transportation tools are also widely used in stainless steel coil plate.China's home appliance industry is a potential large market for the application of stainless steel coil.In addition, stainless steel coil in the water

Corrosion resistanceInternational corrosion resistance of materials according to the annual corrosion rate is divided into three categories, the first category for complete corrosion resistance, the corrosion rate is less than 0.1mm / year, high-quality stainless steel belongs to such materials; the second category for still corrosion resistance, the corrosion rate of 0.1-1.0mm / year, belongs to the general stainless steel; the third category for corrosion resistance, the corrosion rate is greater than 1.0mm per year.Cold rolled descriptionCold rolled: Hot rolled coil is used as raw material,

In the range of 25-300℃, with the increase of deformation temperature, the strength and elongation of the prepared materials decrease gradually in hot rolled, cold rolled and solid solution states. The reason may be that the rise of temperature, the increase of stacking fault energy and the change of deformation mechanism from twinning to slip. 4.210-4-6.
