F51 DUPLEX STEEL RAISED FACED LAP JOINT FLANGES MANUFACTURER, DUPLEX STAINLESS STEEL S32205 LJ FLANGE,

Hex Forge Inc offers a wide range of Duplex Steel F51 Lap Joint Flange to local and international customers at competitive prices. Our duplex steel Lap Joint Flanges provide simple functionality and interchangeability, making them an excellent choice for a wide range of industrial applications. We manufacture Duplex Steel F51 Lap Joint Flange in various alloys, materials, standards, and specifications to meet industry needs.

This grade’s chemical makeup is remarkable, resulting in superior corrosion resistance. F51 Lap Joint Flange is made of Duplex Steel that resists chlorine attack and stress corrosion cracking. Chemical, paper, and food processing industries, as well as refrigeration, use Astm A182 Gr F51 Duplex Lap Joint Flange. In the case of a weakly corrosive environment, no post-weld annealing is necessary. Due to embrittlement, the ASTM A182 F51 Lap Joint Flange should not be utilized at temperatures exceeding 300 degrees Celsius. A two-part assembly with a stub end covered by a lap-joint ring flange is known as a lap-joint flange. This flange connection is beneficial for huge or complex to change flanges. A Duplex Steel F51 Lap Joint Flange is a halving joint, meaning it is made up of two halves that come together to form a whole. Lap joints are basic joints that can be used to build picture frames and mirrors, albeit they are not exceptionally sturdy.

ASTM A182 DUPLEX STEEL F51 LAP JOINT FLANGE SUPPLIER, F51 LAP JOINT FLANGE MANUFACTURER & STOCKIST IN MUMBAI, INDIA.

The flanges have a maximum Brinell hardness of 290HB and a 25% elongation rate. To ensure the best quality of products, we conduct destructive and non-destructive tests. Our flanges are well-packed with all details and documentation and delivered to our clients via safe traditional shipping.
