405 Stainless Steel

405 Stainless Steel

405 stainless steel is a ferritic stainless steel with excellent heat resistance, corrosion resistance and processing performance, and shows good stability and reliability in high temperature and highly corrosive environments.

In high-temperature environments, 405 stainless steel shows good oxidation resistance, can maintain a smooth surface for a long time, and has low surface roughness. It is suitable for manufacturing high-temperature heat exchangers, hot water boilers, heating furnaces and other equipment. In addition, 405 stainless steel also has good resistance to sulfide stress corrosion cracking and can maintain its structural integrity under the action of hydrogen sulfide and other corrosive media. It is suitable for use in harsh conditions such as chemical equipment, petroleum industry, and marine environments.

Grade 405 stainless steel is soaked at 649-760°C (1200-1400°F) and then cooled in air.
Shielded fusion and resistance methods are recommended for welding grade 405 stainless steel. Oxyacetylene welding is not suitable for this stainless steel grade. Hardening of grade 405 stainless steel is controlled by the use of 405 Cb electrodes that contain columbium. Ductility of 405 stainless steel is maximized by post weld annealing.
Grade 405 stainless steel is soaked at 817-871°C (1500-1600°F) and the temperature is then increased to 1038-1121°C (1900-2050°F). Forging below 816°C (1500°F) is not recommended for this stainless steel grade. Forging is followed by air cooling and finally annealing.
Usage of forming techniques enable grade 405 stainless steel to be easily spun, drawn and formed.
Standard methods are used to carry out the machiniability process for grade 405 stainless steel.
Grade 405 stainless steel can be hardened by soaking at 982-1010°C (1800-1850°F) and then oil quenched.
