Strategically based in the industrial heart of Cairo, Egypt, Khaled Stainless stands as a trusted manufacturer and supplier for critical welding needs. We take pride in producing high-quality consumables, including the versatile AWS Class ER630 MIG and TIG filler wire. Our commitment lies in providing welders with reliable materials that ensure strong, durable joints for demanding projects across the region, backed by local expertise and a dedication to supporting the growth of Egypt’s fabrication and construction sectors.
The ER630 welding wire is a 17-4PH stainless steel alloy, known for its combination of strength and corrosion resistance. Its precise composition, primarily chromium and nickel with additions of copper and niobium, allows it to achieve impressive mechanical properties after a simple heat treatment. This process significantly increases its tensile and yield strength, making the final weld deposit remarkably tough and resilient, capable of performing under substantial stress and in challenging environments.
