Fluxes for electroslag strip cladding with
stainless and Ni-base alloys
Cromaflux 480 ESC
Cromaflux 480 ESC is a non-alloying agglomerated fluoride-basic flux designed for electroslag strip
cladding with stainless steel alloys at standard travel speeds (15-25cm/min.). Slag detachment is
excellent, leaving a bright deposit finish with smooth inter-bead tie-in.
Classification: EN ISO 14174 ES A FB 2B 5644 DC
Flux type: Fluoride-basic
Basicity index: 2.6
Flux density: 1.1kg/dm3
Grain size: 2-16
Welding current: DC+
Redrying temperature: 300-350° C/2h
Packaging: 25kg hermetically sealed plastic bags
Cromaflux 450 ESC
Cromaflux 450 ESC is a non-alloying agglomerated fluoride-basic flux designed for electroslag strip
cladding with stainless steel alloys at high travel speeds (25-35cm/min.). Suitable for large diameter
vessels and flat surfaces. Excellent slag detachment, leaving a bright deposit finish with smooth interbead tie-in.
Classification: EN ISO 14174 ES A FB 2B 5644 DC
Flux type: Fluoride-basic
Basicity index: 4.5
Flux density: 1.0kg/dm3
Grain size: 2-16
Welding current: DC+
Redrying temperature: 300-350° C/2h
Packaging: 25kg hermetically sealed plastic bags
Cromaflux 650 ESC
Cromaflux 650 ESC is a non-alloying agglomerated fluoride-basic flux designed for electroslag strip
cladding with Ni-base alloys, e.g NiCr3 and NiCrMo-3 types. Slag detachment is excellent, leaving a
bright deposit finish with smooth inter-bead tie-in. The flux operates over a wide range of travel speeds
and is suitable for both single layer and two layer techniques.
In combination with Cromastrip 625 a single layer deposit of type NiCrMo-3 can be achieved with
around 10%Fe. With the same combination a two layer deposit, 6.5-7.0mm total thickness, can be
achieved with 5%Fe max. at a depth of 3mm below the top surface.
