Stainless Steel 347/347H Washers
Stainless Steel 347 Washers, ASTM A193 347H Stainless Steel Spring Washer, Stainless Steel UNS S34700 Square Washer, SS EN X6CrNiNb18-10 Flat Washers Suppliers in India.
Ranfit Metal & Alloys is a popular trader of SS 347 / 347H Washers, which has good general corrosion resistance. Stainless Steel 347 Flat Washers can be easily welded and processed by standard shop fabrication practices. Stainless Steel 347H Lock Washers cannot be hardened by thermal treatment, but strength and hardness can be increased substantially by cold working, with subsequent reduction in ductility. SS 347 Sealing Washers have excellent forming and welding characteristics. SS 347H Split Washers is used in Aircraft exhaust stacks, Chemical processing equipment, and Manifolds. 347 Stainless Steel Slot Washers has a maximum use temperature of 1500 Degree F (816 Degree C) for code applications. 347H Stainless Steel Machine Washers is stabilized against weld heat affected zone (HAZ) inter-granular corrosion. Stainless Steel UNS S34700 Washers is often used in compensators and expansion bellows. Stainless Steel UNS S34709 Washers has good inherent forgeability, but its differences from carbon and alloy steels must be taken into account.
A heat treatment for Alloy 347 Star Washers after welding is normally not usual. Alloy 347H Spring Washers has excellent resistance to oxidation and corrosion. Grade 347 Wire Spring Washers does not require annealing after being welded. To avoid overheating or burn-through of thinner Grade 347H Flat Spring Washers, higher welding speed has to be applied. Because of its features and properties, Type 347 Flat Washers can be found in use in a number of industries and critical applications.
