Weston Stainless, a UK-based company in Midland, is a prominent manufacturer of premium stainless steel welding consumables for various industrial applications. AWS Class E630-16 Electrodes are one of its specialty products used to weld precipitation-hardening stainless steels like 17-4 PH. Made in standard sizes, these electrodes are a stainless steel alloy supplemented with chromium, nickel, and copper for added strength and resistance to corrosion. They possess superior weldability and find general use in high hardness and toughness applications. E630-16 electrodes find specific use in those industries which expect high mechanical properties in corrosive environments.
AWS Class E630-16 Electrodes consist of about 15-17% chromium, 3-5% nickel, and 3-5% copper, along with controlled carbon content up to 0.03%. They have high mechanical strength, tensile strength of approximately 1000-1200 MPa, yield strength of about 860 MPa, and elongation of 10-15%. Their physical characteristics are a density of about 7.75 g/cm³ and melting range of 1400-1440°C. They possess excellent toughness, impact resistance, and corrosion resistance in harsh environments.
