Introduction

Stainless steels are known as high-alloy steels. These steels are available in four groups that include martensitic, austenitic, ferritic and precipitation-hardened steels. These groups are formed based on the crystalline structure of stainless steels.

Stainless steels contain larger amounts of chromium in comparison with other steels and thus have good corrosion resistance. Most of the stainless steels contain about 10% of chromium.

The chromium content in grade 405 stainless steel is 12%. The following datasheet provides an overview of grade 405 stainless steel.

Fabrication and Heat Treatment

Annealing

Grade 405 stainless steel is soaked at 649-760°C (1200-1400°F) and then cooled in air.

Welding

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.

Forging

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.

Forming

Usage of forming techniques enable grade 405 stainless steel to be easily spun, drawn and formed.

Machinability

Standard methods are used to carry out the machiniability process for grade 405 stainless steel.

Hardening

Grade 405 stainless steel can be hardened by soaking at 982-1010°C (1800-1850°F) and then oil quenched.

Applications

Grade 405 stainless steel is used in quenching racks, annealing boxes, partitions, steam nozzles and various other fabrications that cannot be annealed after welding.
