Description about 430 stainless steel
430 is a ferritic stainless steel, 430 16Cr is a representative type of ferritic steel, thermal expansion rate, excellent formability and oxidation resistance. Heat-resistant appliances, burners, household appliances, type 2 cutlery, kitchen sinks, exterior trim materials, bolts, nuts, CD rods, screens
Because of its chromium content, it is also called 18/0 or 18-0. Compared to 18/8 and 18/10, the chromium content is slightly lower and the hardness is reduced accordingly.
Application about 430 stainless steel
1, 430 stainless steel is mainly used for building decoration, fuel burner components, household appliances, household appliances components.
2. Add 430F steel with free cutting performance to 430 steel, mainly used for automatic lathes, bolts and nuts.
3. If we add Ti or Nb to 430 stainless steel, reduce the C, can get the grade 430LX, the processing and welding performance can be improved, Mainly be used for hot water tanks, hot water supply systems, sanitary appliances, household durable appliances, flywheels, etc. .
Simple comparison about 304 and 430
304 is nickel-containing austenitic stainless steel, and its overall performance is widely used. Due to the nickel content, its price is not low. 430 is a high-chromium ferritic stainless steel and is nickel-free. It was initially developed and promoted by Japan's JFE steel mill. Because it does not contain nickel, the price is not affected by international nickel price fluctuations. The price is low, but due to its high chromium content, it is resistant to corrosion. Excellent performance, food safety is not weaker than 304. Due to its low cost and near-304 performance, it is currently in an alternative 304 position in many applications.
