AISI 420M NACE is a high-strength martensitic stainless steel designed for sour service environments in the oil and gas industry. It offers excellent resistance to sulfide stress cracking and hydrogen-induced cracking, meeting the requirements of NACE MR0175/ISO 15156. With controlled hardness and improved toughness, AISI 420M NACE delivers reliable performance in applications exposed to both mechanical stress and corrosive H₂S conditions.
Because of its unique blend of mechanical strength and corrosion resistance, AISI 420M NACE is widely used in industries where safety and durability are non-negotiable.
Typical applications of AISI 420M MOD / UNS S42000 include:
