303 is a free-cutting stainless steel containing sulfur and selenium respectively. It is used in occasions where easy cutting and high gloss are mainly required. 303 stainless steel improves cutting performance and high temperature bonding performance. Best for automatic lathes. Bolts and nuts.

303 stainless steel is an austenitic free-cutting stainless acid-resistant steel. In order to improve the performance of the steel, no more than 0.60% of molybdenum can be added to the steel.

It can resist ablation, and the product has good machinability and burning resistance. Corrosion resistance. Mechanical properties of 303 stainless steel After annealing to relieve stress, the tensile strength is 515MPa, the yield is 205MPa, and the elongation is 40%. The standard hardness of stainless steel 303 is HRB 90-100, HRC 20-25, note: HRB100 = HRC20.

Stainless steel is made oxidation resistant by local oxidation of chromium, which forms a very stable oxide (Cr2O3 chromium oxide). As long as the chromium content of the metal is sufficient, a continuous layer of chromium 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 estimated from the chromium content. The high temperature resistant alloy contains at least 20% chromium (percentage by weight). Replacing the iron component with a nickel component also generally improves the alloy's performance at elevated temperatures. 309/309S, 310/310S are high-alloy materials, so they have quite good oxidation resistance.

310 heat treatment/annealing

The main reason for annealing these alloys is to produce a recrystallized microstructure, achieve a uniform grain size, and break down harmful chromium carbide precipitates.
