Material 1.4550 is a stainless steel known for its resistance to intergranular corrosion both in the heat-treated condition and after sensitizing heat treatment. Closely related to the 1H18N9T type, it offers superior oxidation resistance. This steel is well-suited for deep drawing and is fully weldable, with no need for 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 found in cryogenics, the pharmaceutical industry, food processing, dairies, sugar factories, breweries, the fuel sector, refineries, and petrochemical plants.
