1.4550 Stainless Steel

All You Need to Know About Precipitation Hardening Stainless Steel X6CrNiNb18-10, 1.4550 According to EN 10088-3


What is 1.4550 Stainless Steel Grade

1.4550, could be a steel immune to intergranular corrosion during a heat-treated state and after a sensitizing heat treatment. In terms of destination, is appreciate the 1H18N9T grade, however, is characterized by higher resistance to oxidation. Steel products are suitable for deep drawing and are fully weldable. The grade doesn’t require additional heat treatment after welding. Conducted tests per PN-H-04630 in polish grade 0H18N12Nb test A show that the steel is proof against intergranular corrosion within the heat-treated state and after the sensitizing treatment. The 1.4550 grade is employed within the industry equipment manufacturing aqua fortis and derivatives, salts and fertilizers. Also utilized in cryogenics, within the pharmaceutical industry, within the food industry – in food processing plants, dairies, sugar factories, breweries, within the fuel industry, i.e., in refineries and petrochemical plants. Steel intended for pipelines, autoclaves, transport tanks, heat exchangers, absorption towers, pumps, coolers, and reactors.
