ALLOY STEEL ASTM A335 P11 P22 P5 P9 BLACK PAINTING BA
ASTM A335 covers “low-alloy” steel pipes， i.e. pipes that have a total amount of alloying elements below 5%. The addition of higher percentages of alloying elements (example Nickel and Chromium) transforms the steel into higher alloys， like stainless steel， duplex， up to super-alloyed materials like Inconel， Hastelloy， Monel， etc.
Alloy steel pipes are used in the energy industry for high temperature and very low-temperature service (cryogenic)， or for applications with very high pressures.
