316 is a special stainless steel, due to the addition of Mo elements to corrosion resistance, and high temperature strength has greatly improved, high temperature up to 1200-1300 degrees, can be used under harsh conditions.
430 stainless steel is a general-purpose steel with good corrosion resistance. Its thermal conductivity is better than that of austenite. Its coefficient of thermal expansion is smaller than that of austenite. It is resistant to thermal fatigue and added with stabilized elemental titanium. The mechanical properties of the weld are good. 430 stainless steel for building decoration, fuel burner parts, household appliances, appliances components. 430F is added to the 430 steel easy cutting performance of steel, mainly for automatic lathes, bolts and nuts. 430LX Adds Ti or Nb to 430 steel to reduce C content and improve workability and weldability. It is mainly used in hot water tanks, hot water supply systems, sanitary wares, household durable appliances, bicycle flywheels etc.
304 stainless steel is a versatile stainless steel, rust-proof performance than the 200 series of stainless steel stronger. High temperature is also better, can be high to 1000-1200 degrees. 304 stainless steel has excellent stainless steel corrosion resistance and better resistance to intergranular corrosion. Of the oxidizing acid, in the experiment concluded that: concentration ≤ 65% of nitric acid below the boiling temperature, 304 stainless steel has a strong corrosion resistance. Alkali solution and most organic acids and inorganic acids also have good corrosion resistance.
