Stainless Steel 446 Screw Manufacturers In India

Sachiya Steel International is one of the Leading Manufacturer And Exporter Of High Quality Stainless Steel 446 Screw, which has a high strength and good corrosion resistant austenitic alloys. Stainless Steel 446 Hex Head Screws has nearly double the yield strength of SS 304 and SS 316 and has better corrosion resistance than 317L stainless steel. These Stainless Steel 446 Socket Head Cap Screws remains non – magnetic even after being severely cold worked. Room temperature forming is suggested in Stainless Steel 446 Socket Set Screws, along with sigma formation should be anticipated and care should be taken to avoid heavy mechanical impact at room temperature.

Stainless Steel 446 Screw

Although improvements in machinability in the past have been associated with reduced corrosion resistance, these Stainless Steel 446 Anchore Screws has been shown to have corrosion resistance within the range typically expected to 304 / 304L stainless steel. Because of its low carbon content, Stainless Steel 446 Blind Rivet Screws retains this corrosion resistance in the as – welded condition.

These Stainless Steel 446 Concrete Screws is a versatile, general purpose stainless steel with good resistance to atmospheric corrosion, to many organic and inorganic chemicals, and to food and beverages. Stainless Steel 446 Threaded Screws has also been used in vacuum processing equipment and specialized instruments where high integrity is essential. These Stainless Steel 446 Steel Shoulder Screws maintains strength at high temperatures as well as sub – zero temperatures.
