Material 1.4550 is a stainless steel with excellent resistance to intergranular corrosion, even after heat treatment or sensitization. It is similar to grade 1H18N9T but offers higher oxidation resistance. This steel is well-suited for deep drawing and is fully weldable without the need for additional heat treatment after welding.
Grade 1.4550 is widely used in the chemical industry for the production of nitric acid, derivatives, salts, and fertilizers. It is also employed in cryogenics, pharmaceuticals, food processing (including dairies, sugar factories, and breweries), as well as in the fuel, refinery, and petrochemical industries.
