Description

Stainless steel electrode for repair works

Classification

AWS A5.4 : ~E 312-16
EN 1600 : E 29.9 R 32
ISO 3581 : E 29.9 R 23

Properties and application

Rutile-basic coated electrode producing an austenitic–ferritic stainless steel weld. Suitable for joining dissimilar materials (stainless steel to low-alloy steel) and welding difficult steels (tool steels, manganese steels, spring steels).

The deposited metal has good crack resistance, suitable as a buffer layer before hardfacing. Smooth weld, self-releasing slag.

Application: heavy vehicle repair, railway industry, sawmills, light industry, food and gas sectors.
