Alloy 20 Pipe Suppliers

Alloy 20 Pipe  made by an austenitic stainless steel developed for applications involving sulfuric acid. Incoloy Alloy20 Pipe has corrosion resistance also finds other uses in the chemical, petrochemical, power generation, and plastics industries. Alloy 20 Seamless Pipe  can be formed by either hot-working or cold-work using traditional methods.Alloy 20 Round Pipe is an excellent option when chloride stress corrosion cracking is an issue and resists pitting and crevice corrosion. Alloy 20 Welded pipe also contains niobium for stabilization against sensitization and resultants inter – granular corrosion. Sch40 Alloy 20 Pipe is virtually nonmagnetic, even at quite low temperatures.
