Sachiya Steel International is a well-known firm that distributes a wide range of SS 321 Threaded Forged Fittings, where post weld heat treatment is not necessary. Stainless Steel 321 Forged Threaded Fittings is used for welding under conditions which prevent a post-weld anneals. Some typical areas of application of Stainless Steel 321H Forged Threaded Fittings are furnace components.
Stainless Steel 321 Forged Threaded Elbow Fittings cannot be hardened by thermal treatment, but strength and hardness can be increased substantially by cold working, with subsequent reduction in ductility. The added titanium content of minimum five times the carbon % content (max 0.7 %) means that Stainless Steel 321H Forged Threaded Tee Fittings also possesses good creep strength and good resistance to chromium carbide precipitation.

Special consideration in Stainless Steel 321 Forged Threaded Cross Fittings is required to avoid weld “hot cracking” by assuring formation of ferrite in the weld deposit. Stainless Steel 321H Forged Threaded Cap Fittings is often used for Expansion joints and Thermal oxidizers.
Stainless Steel 321 Forged Threaded Bend Fittings is similar to Type 304 stainless steel; however, it contains a Titanium addition of at least five times the carbon content. Stainless Steel 321H Forged Threaded Coupling Fittings is also used for Bellows and Furnace parts. Stainless Steel 321 Forged Threaded Union Fittings is used principally for applications involving welding or sustained elevated temperature operations where re-annealing is not practical.

Sachiya Steel International is one of the well-known Manufacture and exporter for high quality SS 310 Threaded Forged Fittings, which are reduced to iron, also called hot metal or pig iron.
After casting and rolling, Stainless Steel 310 Forged Threaded Elbow is delivered as coil, plate, sections or bars.
Stainless Steel 310S Forged Threaded Tee made in fine quality uses electricity to melt recycled steel.
Additives, such as Stainless Steel 310 Forged Threaded Cross are used to adjust to the desired chemical composition.Electrical energy in Stainless Steel 310S Forged Threaded Cap can be supplemented with oxygen injected into the EAF.
Another steelmaking technology, the open hearth furnace (OHF), makes up about 0.4 % of Stainless Steel 310 Forged Threaded production.
The OHF process of Stainless Steel 310S Forged Threaded Coupling is very energy intensive and is in decline owing to its environmental and economic disadvantages.
Sachiya Steel International is one of the Leading Manufacture And Exporter of Stainless Steel 347H Forged Threaded Fittings, which has high corrosion resistance in chloride containing media, including seawater.
Our Stainless Steel 347H Forged Threaded Elbow is a machinability – improved version and is well suited for use in, for example, organic acids.
These Stainless Steel 347H Forged Threaded Tee offers excellent and consistent machining properties for increased cutting speeds, reduced tool wear and set – up times.Our Stainless Steel 347H Forged Threaded Cross is exposed for prolonged periods to temperatures exceeding 300 Degree C (570 Degree F).
The microstructure of these Stainless Steel 347H Forged Threaded Cap changes which results in a reduction in impact strength, where this effect does not necessarily affect the behavior of the material at the operating temperature.Stainless Steel 347H Forged Threaded Fittings | Stainless Steel 347H Forged Threaded Fittings | Stainless Steel 347H Forged Threaded Fittings | Stainless Steel 347H Forged Threaded Fittings Our Stainless Steel 347H Forged Threaded Fittings has a far lower coefficient of thermal expansion than austenitic alloys and can therefore possess certain design advantages.
In terms of resistance to general corrosion, these Stainless Steel 347H Forged Threaded Coupling is comparable or superior alloys in most media.
Compared to our Stainless Steel 347H Forged Threaded Union, which does not contain molybdenum, it is clearly far superior.
Sachiya Steel International is one of the prominent Manufacture and Exporter of Stainless Steel 317L Forged Threaded Fittings, which show a much smaller rate of abrasion volume loss with increase in abrasion velocity than the austenitic steels.
Stainless Steel 317L Forged Threaded Elbow derive their outstanding properties from their capacity to resist unstable fracture of micro shear lips on the abraded surface.This is due to the strain capacity in Stainless Steel 317L Forged Threaded Tee afforded by the mechanical inducement of the martensitic phase transformations and the high work – hardening characteristics of the transformation product.
The influence of this transformation has been studied as a function of prior cold work and velocity of abrasion on a range of austenitic Stainless Steel 317L Forged Threaded Cross.Stainless Steel 317L Forged Threaded Fittings | Stainless Steel 317L Forged Threaded Fittings | Stainless Steel 317L Forged Threaded Fittings | Stainless Steel 317L Forged Threaded FittingsNotwithstanding these advantages of the austenitic grades, Stainless Steel 317L Forged Threaded Cap are superior in terms of cost per unit volume lost and the new ferritic – martensitic steel designated has potential as an abrasion resisting material in corrosive environments.Complex design requirements can make Stainless Steel 317L Forged Threaded fittings necessary to combine different metallic materials within the same component.
Also, chance combinations can often be found in Stainless Steel 317L Forged Threaded Coupling, governed only by the availability of, for instance, fasteners or shims.
In certain circumstances, such mixed – material designs of Stainless Steel 317L Forged Threaded Union can lead to corrosion in one of the partner materials.
