Stainless Steel AISI 305
Data sheet
DIN EN 10088-3
Grade AISI 305 / EN 1.4303
Grade AISI 305 / EN1.4303 is an austenitic stainless steel with good corrosion resistance due to the higher nickel content of 11-13 %. This stainless steel grade is excellently suitable for welding and cold upsetting and has no magnetisability.
Other processing options include cold forming and polishing.
