304 stainless steel ball straight through 400
According to some characteristic elements of main chemical components in steel or steel in the classification, divided into chromium stainless steel, chromium nickel stainless steel, nickel chromium molybdenum stainless steel and low carbon steel, stainless steel, stainless steel and high molybdenum high purity; according to the characteristics and application of classification of steel, stainless steel, divided into nitric acid resistant stainless steel, high resistance to sulfuric acid pitting resistance to stress corrosion of stainless steel, stainless steel, stainless steel and other steel; according to the classification features, divided into low temperature stainless steel, non-magnetic stainless steel, stainless steel, stainless steel, free cutting superplasticity. At present, the commonly used classification methods are classified according to the characteristics of the steel structure, the chemical composition of steel and the combination of the two. Generally divided into martensitic stainless steel, ferritic stainless steel, austenitic stainless steel, duplex stainless steel and precipitation hardening stainless steel, etc., or divided into chromium, stainless steel and nickel stainless steel two categories.
The commonly used stainless steel models are: 201202304316316 and 317 stainless steel (see below the performance of 317 stainless steel) is a stainless steel containing molybdenum. The molybdenum content in 317 stainless steel with 316 stainless steel. Due to a little of molybdenum in steel, the steel overall performance is better than 310 and 304 stainless steel, high temperature, when the concentration of sulfuric acid is less than 15% and more than 85%, 316 stainless steel has been widely used. 316 stainless steel also has good chloride corrosion resistance, so it is often used in marine environments.The maximum carbon content of 316L stainless steel is 0.03, which can be used in welding and can not be annealed and requires maximum corrosion resistance
Many stainless steel grades, different properties, and in the course of its development has gradually formed several categories. According to the structure of the organization, it is divided into four categories: martensitic stainless steel (including precipitation hardening stainless steel), ferritic stainless steel, austenitic stainless steel and austenitic ferrite duplex stainless steel;
