Overview

Stainless Steel 405 is a 12% chromium stainless steel designed to be used in the as-welded condition. Unlike the other grades of 12% chromium stainless, it is not vulnerable to extensive hardening through air cooling from high temperatures. Stainless steel 405 is a ferritic stainless steel It has same corrosion resistance of stainless steel grade 410. The alloy is used in situations where more weldability is desired than 410. It can be easily machined due to its soft and ductile characteristics.

Physical Properties

Mechanical Properties

Hardening

Alloy 405 does not respond appreciably to heat treatment, soaking at 1800-1850 F(982-1010 C) followed by oil quenching will increase mechanical properties.

Annealing

Soak at 1200-1400 F(649-760 C), air cool.

Welding

405 can be welded using shielded fusion and resistance techniques. Oxyacetylene welding is not recommended. Use 405 Cb electrodes that contain columbium rather than aluminum to control hardening. Post weld annealing will maximize ductility.

Soak at 1500-1600 F(817-871 C) and then quickly increase to 1900-2050 F(1038-1121 C). Do not remain at this temperature as the result will be excessive grain growth. Do not work below 1500 F(816C). After forging, air cool and anneal.While this alloy does not respond appreciably to heat treatment, soaking at 1800-1850 F(982-1010 C) followed by oil quenching will increase mechanical properties.

Forging

Soak at 1500-1600 F(817-871 C) and then quickly increase to 1900-2050 F(1038-1121 C). Do not remain at this temperature as the result will be excessive grain growth. Do not work below 1500 F(816C). After forging, air cool and anneal.

Package Process

1.with plastic cap to protect both ends

2.weaving bag wrapped outside the pipe

3.then pack into wooden case.
