Harsh Metalloys is a trusted supplier and stockist of AWS Class E630-16 welding electrodes, located in Mumbai, India. We have expertise in supplying high-quality welding consumables that can satisfy the high demands of industrial uses. The E630-16 electrode is particularly engineered for welding precipitation hardening stainless steels like 17-4 PH, with good strength, corrosion resistance, and hardness after heat treatment. Our electrodes are produced to meet international standards, providing consistent arc performance, smooth weld beads, and low spatter. Harsh Metalloys is dedicated to offering better products, timely delivery, and quality customer service to customers in India and overseas.
AWS Class E630-16 electrodes consist mainly of chromium (15–17%), nickel (4–5%), copper (3–5%), and other elements such as columbium (niobium) and molybdenum in order to simulate the chemistry of 17-4 PH stainless steel. These electrodes produce welds of high tensile strength (normally in excess of 860 MPa) and good hardness following suitable heat treatment. Yield strength is more than 720 MPa, with good ductility and impact toughness. E630-16 can be used with both AC and DC power supplies and forms a solid, crack-free weld. The weld metal has good response to heat treatment, enabling it to equal the base metal’s strength and hardness.

These electrodes offer exceptional corrosion resistance and are ideal for various stainless steel welding applications. They typically come in sizes like 1/8″, 5/32″, and 3/16″. The light coating ensures smooth arc stability and minimal spatter during welding.
Offering robust corrosion resistance, these electrodes are designed for demanding welding tasks on stainless steel. Available in sizes such as 1/8″, 5/32″, and 3/16″, the heavy coating enhances arc stability and slag removal, making them suitable for heavy-duty applications.
These electrodes provide superior corrosion resistance for stainless steel welding with shielded arc protection. They are typically available in diameters of 1/8″, 5/32″, and 3/16″. The shielded arc ensures clean, strong welds with minimal contamination.
AWS Class E630-16 electrodes are commonly applied where a high strength, sound corrosion resistance, and hardness are needed. They are best suited for weldments of 17-4 PH stainless steel parts in aerospace, petrochemical, nuclear, marine, and food process industries. Common applications include turbine blades, shafts, valves, pumps, fasteners, and structural parts needing mechanical strength and dimensional stability. These electrodes offer superior weld integrity in both as-welded and after post-weld heat treatment, and thus are designed for critical service conditions where reliability and performance are critical.
