- FERRITIC - MARTENSITIC STAINLESS STEEL
430
Description
Basic coated electrode
This electrode is suitable for assembling and hardfacing of 15-17% Cr AISI 430 steels. Particularly suitable for refilling carbon steels subject to corrosion and abrasion. During application preheating and interpass: 150 – 260°C. Recommend heat treatment after welding (760–790°C/2h) with slow cooling (55°C/h max) until 595°C in an oven then in air at room temperature. Its basic coating ensures excellent positional welding characteristics with good gap bridging ability.
