Khaleed Stainless is a well-respected manufacturer and supplier of AWS Class ER630 MIG and TIG Filler Welding Wire and Rod based in Riyadh, Saudi Arabia. They provide top-notch welding consumables tailored for specialized applications. ER630, often referred to as 17-4 PH, is a precipitation-hardening stainless steel filler wire specifically designed for welding 17-4 PH and similar alloys. It boasts a combination of high strength, impressive corrosion resistance, and good toughness, making it a dependable choice for critical industrial tasks. This wire is perfect for situations that demand both durability and resistance to harsh atmospheric and chemical conditions.
AWS Class ER630 is primarily composed of chromium (15–17%), nickel (3–5%), copper (3–5%), along with trace amounts of niobium (columbium), manganese, silicon, and carbon. This well-balanced chemistry allows for precipitation hardening, resulting in high strength and toughness after the right heat treatment. Typically, its mechanical properties include a tensile strength exceeding 1000 MPa, a yield strength around 850 MPa, and an elongation of 15–20%. It maintains excellent corrosion resistance across various environments while also offering high hardness and wear resistance.
