Sumit Impex is a well-known producer and supplier of Stainless Steel 304, 304L, and 304H Nuts that are highly regarded for their outstanding features of corrosion resistance and other mechanical properties in various industries. SS 304 Nuts have higher resistance to staining and rusting, making them suitable for extreme temperatures and conditions exposed to moisture or corrosive agents. They can withstand heat up to 870°C (1600°F) and do not corrode easily, maintaining their integrity under high pressure without cracking.
Sumit Impex is a Supplier of Stainless Steel 304 Nuts, Biggest Stockist of 304L/304H SS Nuts as per Standards in Mumbai, India.
Stainless Steel 304 Nuts, ASTM A193 Stainless Steel Coupler Nuts, SS 304 Nylon Insert Nut, ss 304 nut bolt price list, SS 304 Nuts, ss 304 nut bolt manufacturer, 304l Stainless Steel Hex Nuts, SS 304L Hex Nuts, Stainless Steel UNS S30400 Heavy Hex Nuts Exporter, ASME SA 193 304H SS Nuts, SS UNS S30403 Lock Nut Supplier In Mumbai, India .
Stainless Steel 304 Hex Nuts contain 18% chromium and 8% nickel, which contribute to their high resistance to mechanical forces and rust formation. SS 304 Self-Locking Nuts (SS 304 SL) are modifications of the standard 18-8 type, with higher chromium and lower carbon levels. Additional types, such as stainless steel 310H and stainless steel 317L nuts, are available to meet various requirements.
SS 304H nuts are engineered for high-strength applications requiring greater temperature resistance than standard 304-grade nuts. These nuts can withstand extreme temperatures up to 1040°C (1900°F) and provide superior corrosion resistance. Stainless Steel 304H Heavy Hex Nuts, with controlled carbon content, offer improved strength in high temperatures. Environments. exceeding 800°F. These nuts are ideal for use in industries such as oil refining, gas, and chemical processing.
In contrast, Stainless Steel 304L Lock Nuts are designed for lower-temperature applications, including cryogenic storage and food processing equipment, operating at temperatures below -200°F (-130°C). The low carbon content of SS 304L nuts ensures excellent corrosion protection even at low temperatures while making them easier to work with during welding and forming.
Sumit Impex is a leading supplier of Stainless Steel 304 / 304L / 304H fasteners. These fasteners are highly favoured due to their high strength and ability to withstand very high temperatures. The stainless steel 304 series is important for maintaining accurate dimensional tolerance and durability in various applications. Stainless Steel 304L and its associated fasteners are available in various sizes, thicknesses, and lengths with cutting-edge specifications suited to client demands.
UNS S30400 fasteners feature 8% nickel and 18% chromium, giving them an austenitic nature. They are typically used in various stainless steel grades. These fasteners become magnetic after cold working but remain non-magnetic in their annealed condition. Stainless Steel 304L Fasteners offer great resistivity to oxidation at 899°C and ease of welding with various strategies at standard levels. They allow for intermittent presentation at 816°C, and extreme spinning and forming welds can be done for stress relief after annealing.
Stainless steel 304H fasteners are suitable for applications requiring extreme temperature resistance, enhanced by higher carbon content. The increased carbon proportion in this austenitic alloy of chromium and nickel improves tensile and yield strength.
In addition to Stainless Steel 304 Fasteners, Sumit Impex also offers Nickel Alloy 200 Hex Nuts, Aluminum Nuts, and more, catering to a wide range of industrial needs. These products are available in customised sizes to meet specific customer requirements.
