ASTM A268  1/2 Inch Stainless Steel Seamless/Welded 405 Tube

405 Tube：

Stainless Steel Seamless/Welded 405 Tube is a 12% chromium steel, designed to be used in the as welded condition.  Unlike other grades in the 12% chromium category, 405 is not susceptible to extensive hardening through air cooling from high temperature. 

Commonly used for annealing boxes, steam nozzles, quenching racks, partitions and other fabrications that cannot be annealed after welded.

405 Tube Application

Commonly used for annealing boxes, steam nozzles, quenching racks, partitions and other fabrications that cannot be annealed after welding.

405 Tube Machinability

Soft and ductile, 405 can be easily machined using most standard practices. Experienced machinists comment that 405 machines similarly to 4130 alloy steel.

405 Tube 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(816 °C). After forging, air cool and anneal.

405 Tube Annealing

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

405 Tube Hardening

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.
