Njirimara Alloy

SS316L bụ austenitic chromium-nickel igwe anaghị agba nchara nwere molybdenum na obere carbon ọdịnaya.

Nguzogide corrosion:
Organic acid dị elu na oke okpomọkụ.
Acid inorganic, dịka phosphoric na sulfuric acid, n'ogo na oke okpomọkụ.A pụkwara iji ígwè ahụ mee ihe na sulfuric acid nke mkpokọta n'elu 90% na obere okpomọkụ.
Ngwọta nnu, dịka sulfates, sulphides na sulfites.
