Welcome to Golden Steel Material Let’s Talk
An ISO 9001, ISO 14001, OHSAS 18001 Certified Company & PED Certified organization, Golden Steel Material is a premier manufacturer and supplier of Stainless Steel 347H Pipe / Tubes. We are a recognized leader in providing high-performance solutions, including Stainless Steel Pipes, Stainless Steel Tubes, pre-honed tubing, SS 347H Honed Tubing, and Stainless Steel 347H Hydraulic Cylinder Tubes. Based in Saudi Arabia, we maintain a vast warehouse inventory ranging from round and square steel tubes to rectangular, flat-sided oval, and tunnel sections in various Stainless Steel grades. All our stainless steel pipes are furnished in a heat-treated condition, strictly adhering to required heat-treating temperatures and cooling/testing protocols. We ensure full compliance with material specification ASTM A312 and dimensional standards ANSI/ASME B36.19M and ANSI/ASME B36.10M for both Welded and Seamless Wrought Steel Pipe. Our extensive range of seamless and welded pipes conforms to prescribed tensile and yield strengths, with sizes readily available from 6 NB (1⁄8”) to 600 NB (24”) in SCH 10 and SCH 40. For heavy-duty applications, we supply heavier schedules including SCH 80S, SCH 160, and XXS. Specialized grades such as TP304H, TP310H, TP316H, TP321H, and TP347H are high-carbon modifications designed specifically for service at temperatures where creep and stress rupture properties are paramount. Golden Steel Material houses one of the largest regional inventories of Seamless Ferritic and Austenitic Alloy Steel Tubes for Boilers, Superheaters, and Heat-Exchangers. Our stock includes thin-walled and extremely thin-walled austenitic tubes, seamless cold-worked corrosion-resistant tubes, and specialized capillary tubes for Nuclear Power Plant heat-exchange equipment. The chemical composition of Stainless Steel 347H Pipe / Tubes is niobium-stabilized, exhibiting exceptional corrosion resistance and excellent formability. While chosen for their robustness, 347H pipes are primarily utilized in demanding environments such as oil and gas equipment, power stations, chemical and petrochemical plants, petroleum refineries, and natural-gas processing. They are the preferred choice for transmission in Saudi Arabia and the Middle East due to their ability to withstand harsh climatic conditions and extreme internal and external pressures.
