Stainless Steel Flange

To prevent corrosion in the flange cover caused by excessive heating, it is essential to use a welding current approximately 20% lower than that of a carbon steel electrode. Additionally, maintain a short arc length, ensure quick cooling between layers, and opt for a narrow weld bead. When welding stainless steel flange pipe fittings, repeated heating can lead to the precipitation of carbides, which in turn reduces corrosion resistance and mechanical properties. Chrome stainless steel flange pipe fittings tend to exhibit significant hardening and may be susceptible to cracks after welding. To address this, when using the same type of chrome stainless steel electrode (G202, G207), it is necessary to preheat the fittings above 300°C before welding and gradually cool them at around 700°C after welding. Butt welding flange electrodes for stainless steel flange pipe fittings offer exceptional corrosion resistance and oxidation resistance. Due to these properties, they find wide applications in chemical, fertilizer, petroleum, and medical machinery manufacturing industries. Trust in the reliability and durability of our stainless steel flange pipe fittings for your critical applications.
