1. What is stainless steel?
Stainless steel is basically referred to steel which is resistant to acid,steam and water and other weak medium corrosion. It is invented in 20th century with a history of 90 years. Stainless steel is a major achievement in the world of invention in the history of metallurgy. Stainless steel also laid a foundation for the development of modern material industry. Stainless steel has many different grades and specifications, which show different mechanical and chemical properties. Based on organizational classification, it can be classified into martensitic stainless steel (including precipitation steel, hardening stainless steel), ferritic stainless steels, austenitic and ferritic , austenitic duplex stainless steel. Based on mechanical and chemical property, it can be classified into nitric acid-resistant stainless steel resistant acid stainless steel pitting corrosion, stress corrosion resistant stainless steel, high-strength stainless steel. Based on chemical composition, it can be classified into chromium stainless steel, chrome-nickel stainless steel, chrome-nickel stainless steel and carbon steel molybdenum, high molybdenum stainless steel. Based on its functionality, it can be classified into low-temperature stainless steel, non-magnetic stainless steel, free cutting steel, and super-plasticity stainless steel.
Currently, the most widely used classification method is based on characteristics of the organizational structure and chemical composition. It is divided into martensitic stainless steels, ferritic stainless steels, austenitic stainless steel, duplex stainless steel and precipitation hardening stainless steel, and chrome-nickel stainless steel.
2 Application of stainless steel
There are versatile applications, typical use: pulp and paper equipment heat exchangers, dyeing equipment, film processing equipment, pipelines, coastal areas outside the building with other materials.
