TP 304 PIPE

TP304 Stainless steel seamless pipe, also known as 1.4301 stainless seamless pipe or S30400 stainless steel seamless pipe, is the standard austenitic chromium-nickel stainless pipe. It has high corrosion resistance and easy formability. But it can’t resist intergranular corrosion.

TP304 stainless steel seamless pipe are widely used in chemical and petrochemical industry, oil industry, and equipment for foodstuff industry. We inventory TP304 stainless seamless pipe with full size. The outside diameter we manufacture ranges from 6.0mm to 406.4mm.

Our TP304 stainless steel seamless pipe are exported to many countries, like USA, Taiwan, UAE, Japan, Italy, Korea, Singapore, Indonesia, Canada, Malaysia, etc.

XINHANG STEEL provides a lot of processing services, including cutting to length, polishing surface, punching, painting, etc.
