StarBlaze Prime 410-17
AWS A5.4: E410-17
Rutile Coated | Ferritic-Martensitic | Air Hardening
StarBlaze Prime 410-17 is a semi-basic rutile MMA electrode suited for welding 11–13.5% Cr ferritic martensitic stainless steels (AISI 410). It provides a stable arc and clean bead finish for applications requiring post-weld heat treatment (PWHT) to achieve ductility. Suitable for both fabrication and repair, particularly where mechanical working follows welding.
