Stainless Steel  |  Round bar  |  1.4305  |  EN 10278

The stainless steel round bar 1.4305 (X8CrNiS18-9) is a sulfur-alloyed variant of 1.4301, offering significantly improved machinability. Diameters range from 2 to 25 mm. Due to its sulfur content, this material has lower corrosion resistance and is not suitable for food industry applications. The material has an austenitic structure with at least 8% nickel and is generally non-magnetic in the solution-annealed condition. Stainless steel includes corrosion-resistant steels with a minimum of 10.5% chromium, providing good cold forming properties and high resistance to brittle fracture even at low temperatures. Manufacturing is performed by drawing to reduce cross-sections, improve surface finish, and dimensional accuracy. Machinability is enhanced by sulfur addition or work hardening. Standardized according to EN 10088-3 with fit tolerance h9 per ISO 286. Suitable for applications requiring good machinability but moderate corrosion resistance.
