Material 1.4550 is a stainless steel known for its resistance to intergranular corrosion both in the heat-treated state and after sensitizing heat treatment. Closely related to grade 1H18N9T, it offers enhanced oxidation resistance. This steel is deep-drawable, fully weldable, and does not require additional heat treatment after welding.
Grade 1.4550 is widely used in the chemical industry for manufacturing nitric acid, its derivatives, salts, and fertilizers. It is also utilized in cryogenics, pharmaceuticals, food processing (including dairies, sugar plants, and breweries), as well as in the fuel, refining, and petrochemical sectors.
