A182 F347 Flanges Machining

ASTM A182 F347 Hot Forming

Working temperatures of 2100–2250°F (1149–1232°C) are recommended for forging, upsetting and other hot working processes. Do not work this alloy at temperatures below 1700°F (927°C). Material must be water quenched or fully annealed after working to re-attain maximum corrosion resistance.

Werkstoff No 1.4550 Flanges Cold Forming

The alloy is quite ductile and forms easily.

UNS S34700 Welding

stainless steel 347 flanges can be readily welded by most standard processes. A post weld heat treatment is not necessary

347H Stainless Steel Flanges Features

High creep and stress rupture properties
Advantageous for high-temperature service
Excellent resistance to inter-granular corrosion
