Powder electrode strip for surfacing with wear-resistant alloy

摘要

A powder electrode strip for surfacing with a wear-resistant alloy consisting of steel shell filled with a powdered mixture containing the following components in appropriate proportions to the total weight of the powder electrode strip: from 12 to 13 wt.% metallic chromium; from 20 to 22 wt.% iron powder; from 0.2 to 0.3 wt.% graphite; from 1 to 1.2 wt.% ferrochromium with a 0.6-0.8 wt.% carbon content; crystalline silicon or silicocalcium evaluated in terms of silicon at 0.6 to 0.8 wt.%; from 14 to 16 wt.% metallic manganese; from 2 to 3 wt.% titanium dioxide, from 0.6 to 1 wt.% titanium powder, and the balance is now represented by the steel shell.
