◆904L can not only solve the general corrosion of sulfuric acid, phosphoric acid and acetic acid, but also solve the problems of chloride pitting corrosion, crevice corrosion and stress corrosion.
◆253Ma (S30815) is a heat-resistant pure austenitic stainless steel developed on the basis of 21Cr-11Ni stainless steel through N alloying and adding rare earth element Ce. It is mainly used in the production of plates.
◆254SMo (F44/S31254) is a very high-end austenitic stainless steel, which is often used as a substitute for high-nickel and titanium alloys. It is mainly used in many corrosive applications such as chemical and petrochemical processes and chloride solutions.
◆Al-6XN(N08367) is suitable for pumps, valves, flanges and piping systems of oil and gas, chemical and electric power.
