Grade 409 410 420 Stainless Steel Square Bar Bright Anti Corrosion

Stainless steel square steel is mainly used in fine decoration, such as doors and windows.

Stainless steel profiles are used in engineering construction, based on the good corrosion resistance of stainless steel, so it can permanently maintain the integrity of the engineering design for structural components. Chromium-containing stainless steel also combines mechanical strength and high elongation, and is easy to process and manufacture components to meet the needs of architects and structural designers

Heat treatment

This alloy may be hardened by heating to 1500 F followed by a water quench. Carburize at 1650 to 1700 F in an appropriate carburizing medium and oil quench to harden. Improved carburized case and core properties can be obtained by furnace cooling from carburizing at 1650 – 1700 F and then reheating to 1575 F.

Hardening

The AISI steel 8620 will be austenitized at around 840°C – 870°C, and oil or water quenched depending upon section size and intricacy. Cool in Air or Oil required.

Tempering

Tempering of heat-treated and water quenched parts of SAE 8620 steel (not carburized) is done at 400 F to 1300 F to improve case toughness with minimal effect on its hardness. This will also reduce the possibility of grinding cracks.
