Stainless steel is usually classified according to the matrix structure as follows: 1. Stainless steel pipe factory in Shandong provides 1, ferritic stainless steel. Chromium 12% to 30%. Its corrosion resistance, toughness and weldability increase with the increase of chromium content, and resistance to chloride stress corrosion is superior to other types of stainless steel.

2, austenitic stainless steel. Chromium is more than 18%, also contains about 8% nickel and a small amount of molybdenum, titanium, nitrogen and other elements. Good overall performance, resistant to many media corrosion.
3, austenitic-ferritic duplex stainless steel. It combines the advantages of austenitic and ferritic stainless steels and has superplasticity.
4, martensitic stainless steel. High strength but poor plasticity and weldability.
5, precipitation hardening stainless steel. With good forming properties and good weldability, it can be used as an ultra-high strength material in the nuclear industry, aerospace and aerospace industries.
The components can be classified into Cr series (SUS400), Cr-Ni series (SUS300), Cr-Mn-Ni (SUS200), and precipitation hardening series (SUS600).
