Material composition:
Cold rolled steel: mainly composed of elements such as iron, carbon, manganese, silicon, etc., it is obtained by cold rolling hot-rolled steel coils at room temperature.
Stainless steel: On the basis of cold-rolled steel, alloy elements such as chromium and nickel are added, with a chromium content generally not less than 10.5%, which makes stainless steel have better corrosion resistance.
Production process:
Cold rolled steel: The production process is relatively simple, mainly by cold rolling hot-rolled steel coils.
Stainless steel: The production process is relatively complex, including multiple stages such as steelmaking, hot rolling, cold rolling, annealing, acid washing, etc., ensuring the excellent performance of stainless steel.
Performance characteristics:
Cold rolled steel:
High thickness accuracy: The surface is smooth and flat, with high strength and hardness.
Poor mechanical processing performance: suitable for simple directional bending below 90 degrees.
Corrosion resistance is average: it is easy to rust in humid environments.
Stainless steel:
Strong corrosion resistance: able to resist the erosion of various chemical substances.
Excellent mechanical performance: It has high strength and hardness, and performs well in tensile strength and compressive strength.
Good polishing performance: beautiful surface and easy to clean.
