Stainless steel is a kind of material with brightness close to mirror surface, tough and cold to the touch. It is a relatively avant-garde decorative material with excellent corrosion resistance, formability, compatibility and toughness. It is used in heavy industry and light industry. , Daily necessities industry and architectural decoration industries.
Stainless acid-resistant steel is referred to as stainless steel. It is composed of stainless steel and acid-resistant steel. In short, steel that can resist atmospheric corrosion is called stainless steel, and steel that can resist chemical media corrosion is called acid-resistant steel. Generally speaking, steel with chromium content of more than 12% Cr has the characteristics of stainless steel. According to the microstructure after heat treatment, stainless steel can be divided into five categories: ferritic stainless steel, martensitic stainless steel, austenitic stainless steel, Austenitic-ferritic duplex stainless steel and precipitation hardening stainless steel.
