ASTM B729

Nickel Alloy 20 Seamless Pipe and Tube

ASTM B729 Standards And Specifications

The ASTM B729 specification covers UNS N08020 seamless cold-worked or hot finished pipe and tube.

ASTM B729 - Seamless Pipe Tube

ASTM B729 Pipe and Tube

ASTM B729 Seamless pipe and tube is a nickel chromium molybdenum stainless-steel alloy designed for applications including sulfuric acid. The corrosion protection as well finds other uses in the chemical substance, food, pharmaceutical, energy generation, and also plastics manufacturers. Alloy 20 prevents pitting and also chloride ion rust and its copper content defend it from sulfuric acid. Alloy 20 is not a stainless-steel though a nickel alloys (ASTM). Alloy 20 can often be selected to solve stress corrosion cracking issues, which can occur with 316L stainless. It is usually generally known as Carpenter 20. Cast versions are chosen CN7M Alloy 20 has become a well known choice for an array of industries which include the chemical, foods, pharmaceutical, and also plastics manufacturers. Additionally, this superb alloy is required in high temperature exchangers, combining tanks, metal cleansing and also pickling tools, and piping.
