Harris® ER 630 (17-4 PH) 3/32" dia. x 36" stainless steel TIG (GTAW) welding rod comes in a 10 lb. box and is a martensitic precipitation-hardening alloy. ER 630 (17-4PH) is an outstanding choice for applications requiring high strength in both base metals and welds, hardness, good corrosion resistance, good mechanical properties at temperatures up to 600°F (316°C), and short-time, low-temperature heat treatments that minimize warpage and scaling. It is more cost effective than many high nickel, non-ferrous alloys. ER 630 (17-4PH) plate under 4" can be welded without pre-heating, but interpass up to 300°F (149°C) are commonly used. Conforms to ANSI/AWS A5.9 ER 630 (17-4 PH).
Used for welding chemical processing equipment, aircraft components, continuous extrusion equipment, tubular structures, duplication machine components, pressure vessels, small bellows, and diaphragm assemblies
Applications requiring high strength and hardness, as well as corrosion resistance
Caution
All parameters are suggested as basic guidelines and will vary depending on joint design, number of passes and other factors.
