304H Stainless Steel Pipe (UNS S30409) is a modification of the most widely utilized "18-8" chromium-nickel austenitic stainless steel. 304H Stainless Steel Seamless Pipe is an austenitic chromium-nickel steel alloy and the greater carbon content delivers an increased tensile and yield strength. SA312 TP304H Tubing is an economical and versatile corrosion resistant alloy suitable for a wide range of general purpose applications. AISI 304H Tube can be easily welded and processed by standard shop fabrication practices. SS 304H Seamless Tube has improved machinability characteristics. Stainless Steel 304H Seamless Tubing does not perform well in more highly reducing environments such as those containing chlorides and sulfuric acid. SS 304H Erw Pipe is not recommended for service in marine environments.
We offer various sizes of Din W.-Nr. 1.4301 Aisi 304H Round Pipe up to the biggest 4 inches in diameter in 20 feet long. 304H Stainless Steel Rectangular Pipes are available in bright polished finish. We supply Stainless Steel 304H Seamless Round Tubing up to the biggest 4 inches in wall opening in 20 feet long. SS 304H welded square tubes are available in both bright polished and hairline finish. We also stock Steel Pipe 304h up to the biggest 4 inches in wall opening in 20 feet long. SS 304H welded rectangular tubes are available in both bright polished and hairline finish.
