2304 Stainless Steel Seamless Pipe

Grade: 2304/S32304

Size:

Seamless: 6mm*1mm-720mm*50mm

Coiled: 4mm*0.5mm-32mm*3mm

Standard: ASTM A312, ASTM A213 etc.

Surface: No.1(Pickling), Bright(Polished)

2304 Stainless Steel Pipe is a lean duplex stainless steel combining austenitic and ferritic phases to provide high strength, good toughness, and strong resistance to stress corrosion cracking. With lower alloy content than super duplex grades, 2304 offers an economical balance of corrosion resistance and mechanical performance. It is widely used in structural piping, water treatment, chemical processing, storage tanks, and industrial equipment.
