    TP304H Stainless steel seamless pipe, also known as 1.4948 stainless steel seamless pipe, is an austenitic stainless steel pipe. It has excellent heat resistance in raised temperatures.

    ASTM A312 TP304H pipe are widely used in pipeline construction, oil and chemical industry, nuclear technology, and boiler making industry. The increased carbon content delivers a greater tensile and yield strength.

    The austenitic structure of TP304H stainless steel also gives it excellent toughness, even down to cryogenic temperatures. We supply and manufacture this pipe with a wide range of sizes, from 10.0mm to 1219mm.

    The wall thickness of TP304H stainless steel seamless pipe ranges from 1mm to 50 mm. The common length of each pipe is 5.8m, 6.0m, 11.8m. The maximum length we produce is up to 11.8m.

    TP304H Stainless Steel Seamless Pipe is the most common product, which can be cut to size and pipe with polished finish is also available. A lot of processing services, including punching, painting, beveling, chamfering are all available for us.
