Frequently Asked Questions

Can 304 stainless steel be forged?

Yes, 304 stainless steel can be forged. It is one of the most commonly forged austenitic grades. The process requires careful temperature control—typically between 2100°F and 2300°F—to achieve optimal grain refinement and mechanical properties. Forged 304 stainless offers superior strength, ductility, and corrosion resistance compared to cast or machined equivalents, making it suitable for aerospace, chemical, and industrial applications.
