Sachiya Steel International Is One Of The Leading Manufacturer And Exporter Of High Quality Alloy 20 Channel, Angle, Beam, Chain, which cannot be hardened by heat treatment. The austenitic stainless steels such as Alloy 20 Angle are considered to be the most weldable of the high – alloy steels and can be welded by all fusion and resistance welding processes. Alloy 20 C-Channel is annealed in the 1600 Degree F – 1650 Degree F (871 Degree C – 899 Degree C) range and then air cooled to relieve cold working stresses. Alloy 20 Chain should not be exposed to temperatures of 2000 Degree F (1093 Degree C) or above due to embrittlement.

If excessive large grains are encountered after annealing mildly cold – worked material, the annealing temperature of Alloy 20 H-Beam should be decreased to a range of 1200 Degree F – 1350 Degree F (649 Degree C – 732 Degree C) range. For maximum corrosion resistance to chemical environments, it is essential that the surface of Alloy 20 T-Beam be free of all heat tint or oxide formed during annealing or hot working.
Alloy 20 I-Beam should be machined in the annealed condition using surface speeds. All surfaces of Carpenter 20 Angle must be ground or polished to remove any traces of oxide and surface decarburization. The parts of Carpenter 20 Chain should then be immersed in a warm solution of 10 % – 20 % nitric acid followed by a water rinse to remove any residual iron.
