Stainless steel 1.4435 (also known as AISI 316L) is an austenitic stainless steel with high chromium (18%), nickel (12–14%), and molybdenum (2.5–3%) content. These elements provide excellent corrosion resistance, particularly against acids and salts, making it suitable for environments with high humidity and aggressive chemical exposure. This steel also offers resistance to intergranular corrosion due to its low carbon content.
The production of steel 1.4435 involves melting and alloying with chromium, nickel, and molybdenum, which ensure corrosion resistance and mechanical strength. After casting, the material undergoes heat treatment and rolling to achieve an optimal structure. Stainless steel 1.4435 is easily weldable and machinable while maintaining high strength even at low temperatures.
Stainless steel 1.4435 is widely used in the pharmaceutical and chemical industries, for the manufacture of piping, tanks, medical devices, and food processing equipment. Its resistance to aggressive chemicals and corrosion makes it an ideal material for applications where hygienic and corrosion-resistant properties are crucial.
