Why is Stainless Steel So Hard to Machine?
Stainless steel is not one machining material. Austenitic 304/304L and 316/316L, free-machining 303, martensitic 410 or 420, duplex grades, and precipitation-hardening grades such as 17-4PH have different strength, work-hardening behavior, heat-treatment condition, corrosion performance, and chip formation. A useful quotation therefore starts with the exact grade, condition, product form, geometry,
