About Grade 304 Stainless Steel

304 (1.4307) is the most widely used austenitic stainless steel, offering excellent corrosion resistance, strength and a clean bright finish. It is readily welded, machined and fabricated and is well suited to architectural, structural, marine, catering and food-industry applications where hygiene and corrosion resistance matter. For the most demanding marine and chemical environments, grade 316 offers even greater resistance - see our 304 vs 316 guide.

Common Uses

Shafts, pins, spindles and dowels, balustrade and handrail components, brackets and supports, marine and coastal fixtures, catering and food-preparation equipment, gates and railings, and general stainless fabrication and engineering.

FREQUENTLY ASKED QUESTIONS

What grade is the stainless steel round bar?
Grade 304 (1.4307), the most widely used austenitic stainless steel, with excellent corrosion resistance and a clean finish, suitable for welding, machining and indoor or outdoor use.

Can 304 stainless round bar be machined?
Yes. 304 machines with carbide tooling at appropriate speeds. Use cutting fluid to manage heat as stainless work-hardens during machining.
