2205 Stainless Steel Plate

Corrosion resistance

International 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 description

Cold rolled: Hot rolled coil is used as raw material, and the oxide skin is removed by pickling. The product is rolled coil. The cold work hardening caused by continuous cold deformation makes the strength, hardness and toughness and plasticity of rolled coil increase, so the stamping performance will deteriorate and can only be used for parts with simple deformation. Rolled coil can be used as raw material for hot galvanizing plant because annealing lines are set up in hot galvanizing units. The weight of rolled coil is generally 6-13.5 tons. The hot rolled pickling coil is rolled continuously at room temperature. The inner diameter is 610 mm.

Cold rolled edge

Stretch good, toughness, but the price is more expensive;

Cold rolling processing surface without oxide skin, good quality;

Cold rolling is generally used in the production of strip, the rolling speed is high;

Cold rolling than the thickness of the high precision. Mechanical properties, surface and so on in the hot rolling;

Cold-rolled steel coil due to a certain degree of work hardening, low toughness, but can achieve better yield ratio, used for cold-formed spring and other parts;

Cold coil yield point closer to the tensile strength, so the use of risk in the process of no predictability, when the load exceeds the allowable load prone to accidents

The surface of the cold rolled steel coil without plating is gray.

Cold rolled steel plate surface smoothness is higher than the hot rolled steel coil.
