310 stainless steel is austenitic chrome-nickel stainless steel with excellent oxidation resistance, corrosion resistance, because of the higher percentage of chromium and nickel, 310S has much better creep strength, can continue operation at high temperatures, has good high temperature resistance.
310S corresponds to the domestic brand 0Cr25Ni20,

310 High Temperature Oxidation Resistance:
Stainless steel through the local oxidation of chromium to make it oxidation resistance, in the process of local oxidation of chromium, can form a very stable oxide (Cr2O3 chromium oxide). As long as the chromium content of the metal is sufficient, a continuous layer of chrome oxide green can be formed on the metal surface to prevent the formation of other oxides and protect the metal. The oxidation resistance of austenitic stainless steel can be calculated by the chromium content. High temperature resistant alloys contain at least 20% chromium (* by weight). Substituting a nickel component for an iron component also usually provides alloy performance at high temperatures. 309/309s and 310/310s are high alloy materials, so they have good oxidation resistance.
310 Heat Treatment/Annealing:
The main reason for annealing these alloys is to produce a recrystallized fine structure to achieve uniform grain size and to decompose harmful chromium carbide precipitates.

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 Stainless Steel Sheet / Plate:
- 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.
