Sachiya Steel International is one of the Leading Manufacture of Stainless Steel 446 Tube to Union Fittings, which should be in the fully solution treated condition prior to welding. Our Stainless Steel 446 Tube Fittings is a cobalt base super – alloy with a unique combination of high temperature strength and oxidation resistance, along with adequate ductility after prolonged exposure to the 1400 Degree F – 1600 Degree F temperature range. These Stainless Steel 446 Compression Fittings has an inherent advantage over the nickel base grades in high temperature creep.

Our Stainless Steel 446 Union Fittings is solid solution strengthened by a 14 % tungsten addition, which is further sensitive to strain age cracking during welding. These Stainless Steel 446 Union Tube Fittings is readily fabricated, being welded by both manual and automatic methods including electron beam, gas tungsten arc and resistance welding. In our 446 Stainless Steel Tube Fittings, gas tungsten arc welding is normally carried out using argon shielding gas. These 446 Stainless Steel Compression Fittings is normally welded in the annealed condition 2100 Degree F, and then rapid cool.

After welding, the assembly of our 446 Stainless Steel Union Fittings may be aged 8 hours at 1470 Degree F, and then air cool. Repair welding components of these SS 446 Union Fittings may be done in the age hardened condition, where sound welds can be made by the resistance and electron beam methods.
