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.

Hot Rolled Stainless Steel, also known as inox steel, is a steel alloy with a minimum of 10.5 or 11% chromium content by mass. Hot Rolled Stainless steel Plate ...Material Supply:ASTM/ASMEGradeEN GradeChemical Component %CCrNiMnPSMoSiCuNOther201≤0.1516.00-18.003.50-5.505.50－7.50≤0.060≤0.030-≤1.00-≤0.25-3011.4310≤0.1516.00-18.006.00-8.00≤2.00≤0.045≤0.030-≤1.00-0.1-3041.4301≤0.0818.00-20.008.00-10.00≤2.00≤0.045≤0.030-≤0.75---304L1.4307≤0.03018.00-20.008.00-10.00≤2.00≤0.045≤0.030-≤0.75---304H1.49480.04~0.1018.00-20.008.00-10.00≤2.00≤0.045≤0.030-≤0.75---309S1.4828≤0.0822.00-24.0012.00-15

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.

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.

Production process:Stainless steel checker plate is divided into two categories:One is rolled by a rolling mill in the production of stainless steel by a steel mill. The thickness of this type of product is about 3-6mm, and it is in the state of annealing and pickling after hot rolling.

Advantages:Forming speed, high yield, can be made into a variety of cross section forms, to meet the needs of the use conditions; Cold rolling can produce large plastic deformation of steel, thus raising the yield point of steel. Hot rolling can destroy the casting structure of steel ingot, refine the grain size of steel, and eliminate the defects of microstructure, so that the microstructure of steel is compact and the mechanical properties are improved.Disadvantages:1.

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,
