Ultra-Corrosion-Resistant Alloy 20 Stainless Steel
- Yield Strength: 35,000 psi
- Hardness: Rockwell B95 (Medium)
- Heat Treatment: Annealed (Softened)
- Heat Treatable: No
- Specifications Met: ASTM B473
A high nickel content allows Alloy 20 stainless steel to stand up to harsh chemicals in caustic environments. It's also known as Carpenter 20. Maximum temperature for corrosion resistance is not rated.

Standard-Wall Stainless Steel Threaded Pipe Nipples and Pipe
Designed for low-pressure flow applications, this pipe is also known as Schedule 40. Alloy 20 stainless steel pipe has the best corrosion resistance of all the stainless steel pipe we offer. Alloy 20 stainless steel is also known as Carpenter 20 and resists cracking from stress and corrosion.
Seamless pipe has a smooth interior for unrestricted flow and is stronger than welded pipe.
Fully threaded pipe is also known as a close nipple; it is threaded on each end to the center.
