Unifit Metalloys Inc. is a prominent seller of SS 347 / 347H Stud Bolts, which are essentially nonmagnetic as annealed and become lightly magnetic when cold worked. Stainless Steel 347 Stud Bolts is a low carbon version of grade and is less prone to embrittlement and sensitization in service. Stainless Steel 347H Stud Bolts is used in retorts, muffles, annealing covers, saggers, food processing equipment, cryogenic structures, etc. SS 347 Stud Bolts can be utilized in slightly oxidizing, nitriding, cementing and thermal cycling applications, albeit, the maximum service temperature must be reduced. SS 347H Stud Bolts is also used in Power Generation — coal gasifier internals, pulverized coal burners, tube hangers, and more.
347 Stainless Steel Stud Bolts is used in wide application such as in all high-temperature environments where scaling and corrosion resistance. Attributing to the diligent team of procuring agents, we have been capable of making a range of supreme quality products like 347H Stainless Steel Stud Bolts available to our clients. Due to its high chromium and nickel content, Stainless Steel UNS S34700 Stud Bolts is superior in most environments.
Their fusion point is lower than that of non-alloyed steels, and therefore Stainless Steel UNS S34709 Stud Bolts have to be welded with lower heat input than non-alloyed steels. The key properties of this Alloy 347 Stud Bolts are its high chromium and medium nickel content making its resistance to oxidation, suffixation and other forms of hot corrosion its main characteristics.
