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.
