Sachiya Steel International Is One Of The Leading Manufacturer And Exporter Of High Quality Stainless Steel 310H Tube to Union Fittings similar to parker and Swagelok, which is the basic 18 / 8 austenitic steel stabilized with Titanium. Stainless Steel 310H Tube Fittings is not sensitive to inter – granular corrosion after heating within the carbide precipitation range of 425 Degree C – 850 Degree C. Stainless Steel 310H Compression Fittings is the grade of choice for applications in the temperature range of up to about 900 Degree C, combining high strength, resistance to scaling and phase stability with resistance to subsequent aqueous corrosion.
Stainless Steel 310H Union Fittings is a modification of Type 321 with a controlled higher carbon content, to provide improved high temperature strength. A limitation with Stainless Steel 310H Ferrule Fittings is that titanium does not transfer well across a welding arc, so is not usable as a welding consumable. Stainless Steel 310H Double Ferrule Fittings is therefore used – the niobium performs the same carbide stabilization task but can be transferred across a welding arc.
310H Stainless Steel Compression Fittings is only occasionally used as parent plate material. Like other austenitic grades, 321 has excellent forming and welding characteristics, is readily brake or roll formed and has outstanding welding characteristics. 310H Stainless Steel Tube Fittings is therefore the standard consumable for welding Grade 321. Post – weld annealing in 310H Stainless Steel Union Fittings is not required.
