UNS S31803 Hex bolt and Din 1.4462 studs manufacturer in India
ASTM A182 F51 Bolts are a grade of high temperature service bolts and nuts. There are different shapes and types such as the UNS S31803 Hex Bolt which is stronger and the 1.4462 Studs which are highly viable in elevated temperatures. The ASTM A182 Gr F51 Nut is forged and therefore is hard enough to withstand high temperatures.

Check standard specification of Duplex Grade F51 Threaded Rod, Buy Polished & PTFE Coated astm a182 gr f51 Bolts at lowest price in India
The material is duplex steel so that it has both the corrosion resistance and the strength from the austenitic and ferritic phases of the steel. The Duplex Grade F51 Threaded Rod is used to fit on with threaded accessories. There are ASTM A182 Gr F51 Hex Bolt types as well as other types. The ASTM A182 Super Duplex Steel Hex Bolts have better grip, strength and are corrosion resistant. They could be used along with the Super Duplex Steel Gr F51 Hex Cap Screw which is directed by a hex cap through to the bolt hole. The Super Duplex Alloy Gr F51 Hex Screw is high wear and tear and it is used in applications that have removable parts. The Gr F51 Socket Cap Screw makes the tightening and loosening of the screw because of the socket cap. Our ASTM A182 Gr. F51 Hex Bolts are used in marine and sea water applications as well as power plants and engine parts. We also manufacture Gr F51 Heavy Hex Bolt which can last longer under high wear and tear conditions. Our ASTM A182 Grade F51 Hex Cap Screw and other products are all quality tested and are made from high quality material according to international standards.
