A mandrel bend of 2 3/4" OD tube in 20 gauge 321 stainless steel. Bent to 79 degrees with a center line radius of 4". The bend has 6" & 16" long legs.
321 Stainless Steel – similar to 304 but lower risk of weld decay due to addition of titanium of five times the carbon content. It has excellent resistance to oxidation and corrosion and good creep strength. 321 can be readily formed and drawn and has excellent resistance to organic chemicals, inorganic chemicals and dyestuffs. Excellent high temperature fatigue and cracking resistance which makes it advantageous for high temperature service.
- Superior heat retention properties
- Alloyed with Titanium
