经济型高氮奥氏体不锈钢研究进展
Research Progress of Economical High Nitrogen Austenitic Stainless Steel
摘要
Abstract
A new type of resource saving high nitrogen austenitic stainless steel with high strength,high corrosion resistance,and high economy is introduced.The performance advantages,mechanisms,and research progress of high nitrogen austenitic stainless steel series in terms of strength,corrosion resistance,and weldability is elaborated.Research has shown that the high nitrogen austenitic stainless steel series has high strength,excellent local corrosion resistance,and good weldability.At the same time,replacing expensive nickel and molybdenum with low-cost manganese and nitrogen can greatly reduce production costs,and has broad market application prospects.It is recommended to optimize welding processes and welding filler materials in a timely manner according to specific application scenarios in the future to ensure the long term reliability and safety of high nitrogen austenitic stainless steel.关键词
