Cromaflux 380

Classification

EN ISO 14174-A S F CS 2 DC H5

Flux for submerged arc welding

Description

Cromaflux 380 is a fused, calcium-silicate flux intended for use with Ni-base wires where it provides

excellent slag detachability, even in restricted joints, and clean, bright deposit finish with low bead

profile and smooth tie-in. Cromaflux 380 is also suitable for use in combination with austenitic and

duplex stainless steel wires for high speed fillet welding, using the single or twin-arc process, or where

welding at the lower current range is required, e.g. thinner material. Being non-hygroscopic (fused), it

can further be used to weld low alloy-high strength steels where very low hydrogen levels are critical.

Cromaflux 380 is for use on DC only and is suitable for butt welding 9% Ni steels in combination with

Cromasaw 625, butt welding with alloy 59 and alloy C276 wires, cladding with Ni-base wires, high

productivity fillet welding with austenitic and duplex stainless steel wires and power generation fin-tube

walls in P91 steel.
