Stainless Steel Electrodes

ES 318 17 A5.4: E 318- 17 / EN 1600: E 19 12 3 Nb R 32

Description

ES 318 17 It is a low carbon rutile coated electrode. It gives a filler metal of the Cr-Ni-Mo type. It can also be used in the welding of niobium or titanium stabilised AISI 318 or similar quality stainless steels. Excellent quality smooth weld beads are highly resistant to acids and to inter granular corrosion at operating temperatures up to 350°C. It gives a stable arc and the slag is easy to remove. Re-drying is 300°C min. 2 h
