Welcome to Golden Steel Material Let’s Talk
Golden Steel Material is a premier ASTM A403 WP 310/310S Stainless Steel Pipe Fittings Supplier in Saudi Arabia, designed for critical applications operating in extreme temperature environments. Grade 310/310S is widely known as the "25-20" stainless steel, featuring a high alloy balance of 25% Chromium and 20% Nickel. This metallurgical composition provides exceptional resistance to oxidation and scaling, making it the preferred alloy for continuous operation in temperatures up to 1100°C (2000°F). Whether serving furnace components, burner assemblies, or kiln process piping, our 310 fittings provide the unrivaled thermal endurance required for intense heat service.
As a specialized WP 310 pipe fittings stockist, we deliver components manufactured strictly to ASTM A403 and ASME SA403 specifications. The "WP" designation confirms that our fittings have undergone the necessary wrought manufacturing processes to meet rigorous pressure-temperature class requirements. Our inventory encompasses both WP-S (seamless) and WP-W (welded) configurations. By utilizing 310S (Low Carbon) variants, we further ensure that the fittings maintain excellent resistance to intergranular corrosion, which is a critical factor when piping systems undergo cyclical thermal loading or are subjected to sulfur-bearing atmospheres common in high-heat processing.
We serve as a trusted 310/310S stainless steel pipe fittings exporter in Saudi Arabia, supplying high-performance infrastructure across the Jubail, Yanbu, and Dammam industrial hubs. Every fitting is supported by MTC EN 10204 3.1 certification and undergoes rigorous quality inspections, including PMI (Positive Material Identification) and dimensional accuracy checks per ASME B16.9 and B16.11 standards. When your piping design demands the highest level of oxidative stability under extreme heat, our 310/310S fittings provide the metallurgical reliability required to minimize maintenance costs and prevent premature component failure.
