316L Stainless Steel Fasteners

UNS S31603 Bolts, Nuts, Studs and hex head screws manufacturer, check DIN 1.4404 bolts torque chart here

316L Stainless Steel Fasteners are used for their low carbon nature with corrosion resistance to sea water. The material has carbon, manganese, sulfur, silicon, phosphorus, nitrogen, 18% chromium, up to 14% nickel and up to 3% molybdenum in the composition. Viha Steel & Forging is a leading manufacturer of stainless steel 316l bolts and nuts and other fasteners. The material composition provides the fasteners with 170MPa minimum yield strength and 485MPa minimum tensile strength. The elongation rate is 40% and the Brinell hardness score is 217.

The Astm A193 316l Fasteners are intended for high pressure, high temperature services. These are used in boilers, heat exchangers, petroleum refineries, oil and gas and in marine applications. The SS DIN 1.4404 Fasteners can come in sizes ranging from M4 to M16 with diameters ranging from 12mm to 72mm for different classes and types. The length of the different SS UNS S31603 Fasteners can vary up to 160mm as well. The material is resistant to hydrochloric, sulfuric, acetic and formic acid components as well. The fasteners have good creep resistance and rupture resistance. The 316l stainless steel threaded rod is used without the need for nuts. These rods can have threads on both ends or on one end.

Also, the thread type and thread length vary for these threaded rods. The 316l Stainless Steel hex head screws are driven in place with screw drivers. The hexagonally shaped heads of the screws make them easy to install and uninstall. The screws could be seen in narrow space applications such as motors, engine parts and equipment. As a leading manufacturer, we supply the 316l stainless steel bolts and nuts in different sizes and shapes under different specifications and standards. Please feel free to contact us for more information and pricing of these 316L fasteners.
