Similar to ER410, except for slightly higher chromium and carbon contents, it is used for many surfacing operations requiring corrosion resistance provided by 12 percent chromium along with
somewhat higher hardness that increases wear resistance. Predominantly used for surfacing of sealing faces
of valves for gas, water, and steam piping systems at service temperatures up to +450 °C. Application include welding of similar parental metal, weld overlay and thermal spraying. Suitable for cladding of continuous casting rolls. If
parts are to be used in the “as-welded“
condition, a ductile joint can be achieved
by using austenitic fillers such as 22 12 L/309, 18 8 Mn/307 or 25 20/310.
Ferritic martensitic stainless steels.
microstructure comprises tempered
martensite and some carbide.
Materials to be welded
Corrosion resistant Cr-steels as well as other similar-alloyed steels with C-contents
≤ 0.30 % (repair welding), heat resistant Cr-steels of similar chemical composition. EN W.Nr.: 1.4006 (X12Cr13), 1.4021 (X20Cr13),
+ ASTM: 410, 420.
