Product Description
ER 630 (17-4 PH) is a top - notch choice for the aerospace and other high - tech industries. With a nominal composition of 16.4 Cr, 4.7 Ni, 3.6 Cu (wt. - %), it's mainly designed for welding ASTM A 564 Type 630 and certain precipitation - hardening stainless steels. Its composition is adjusted to avoid ferrite networks in the martensitic microstructure, which could harm mechanical properties. Depending on your application and weld size, you can use the weld metal as - welded, welded and precipitation hardened, or welded, solution treated, and precipitation hardened.
To use this Crown Alloys 17 - 4PH/630 stainless steel TIG rod, first, make sure your welding equipment is set up correctly according to the manufacturer's instructions. When welding, keep a steady hand to ensure a smooth and even weld. For different applications and weld sizes, you can choose different treatment methods. You can use the weld metal right after welding, or you can further harden it through precipitation hardening. Sometimes, a solution treatment followed by precipitation hardening might be needed. As for maintenance, store the rod in a dry place to prevent rusting. If you notice any damage to the rod, don't use it as it may affect the welding quality.
