Stainless Steel 317 Screw Manufacturers In India

Sachiya Steel International is one of the Leading Manufacturer And Exporter Of High Quality Stainless Steel 317 Screw, which can be successfully welded by all standard methods, where preheating is not necessary. Properties of Stainless Steel 317 Hex Head Screws comparable to those of the parent metal may be achieved in the weld metal by post – weld heat treatment. As for other high strength steels, precaution should be taken in design and welding procedures of these Stainless Steel 317 Socket Head Cap Screws to avoid concentration of weldment stresses.

Stainless Steel 317 Screw

After solution treatment a single low temperature “age hardening” treatment is employed to achieve required properties of Stainless Steel 317 Socket Set Screws. Heat treatment in these Stainless Steel 317 Anchors Screws results in no distortion and only superficial discoloration, where a slight decrease in size (shrinkage) takes place during the hardening. In solution treated, Stainless Steel 317 Blind Rivet has lower resistance to stress corrosion cracking, and lower ductility compared to aged conditions.

These Stainless Steel 317 Concrete Screws should not generally be used in the solution treated condition, even if the hardness is considered satisfactory. Stainless Steel 317 Threaded Screws has good oxidation resistance, but to avoid reduction of its mechanical properties and hardness it should not be used above its age hardening temperature. The great benefit of these Stainless Steel 317 Steel Shoulder Screws is that they are generally supplied in the solution treated condition.
