Abstract

An anticorrosion stainless steel contains Cr (19-28 Wt%), Ni (0.2-0.5), C (0.02-0.05), Si (0.5-0.7), N (0.04-0.1), P (0.02-0.35), S (0.01-0.03) and Fe (rest). Its advantages are high anticorrosion power, thermel conductivity and machinability.

Description

technical field [0001] The invention relates to a stainless steel material, in particular to a stainless steel with good corrosion resistance. Background technique [0002] Compared with other alloy steels, stainless steel is a special steel with high corrosion resistance. It can resist corrosion in the air or in chemically corrosive media, and also has a beautiful surface. It does not need surface treatment such as color plating. Used in a variety of applications, from household appliances, tableware, the automotive industry to as a building material, its durability and virtually maintenance-free surfaces are two attributes that have prompted people to pay more attention to their applications than ever before. Nickel and molybdenum are usually added to stainless steel. Nickel is an excellent corrosion-resistant material and an important alloying element for alloy steel. Nickel is an element that forms austenite in steel and can change the structure of high-chromium steel. ...
