Welcome to Golden Steel Material Let’s Talk
Golden Steel Material is a premier Stainless Steel 347 Tubes Supplier in Saudi Arabia, offering high-performance piping solutions for the Kingdom’s critical high-temperature and high-pressure sectors. Our ASTM A312 TP347 tubes are stabilized with Columbium (Niobium), providing exceptional resistance to intergranular corrosion and chromium carbide precipitation when exposed to temperatures in the 427°C to 816°C range, common in Jubail’s petrochemical plants.
As a leading SS 347 Seamless Tubes stockist, we supply materials that offer slightly higher creep and stress rupture properties than Grade 321. These tubes are the definitive choice for radiant superheaters, boiler tubes, flare stacks, and heavy-wall refinery components in Yanbu, Dammam, and Riyadh. The addition of Columbium ensures that the material maintains its structural integrity and chemical stability even under the most severe thermal stresses found in Saudi Arabia's heavy power generation infrastructure.
We act as a trusted Stainless Steel 347 Tubes exporter in Saudi Arabia, ensuring all products meet ASME SA213 and SA312 standards. With competitive lead times and a robust inventory for major refinery turnarounds, we provide Saudi industrial contractors with durable 347 tubing solutions that maximize service life and minimize risk in volatile high-heat environments.
