Abstract
Abstract 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.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
101 words
A powder electrode strip for surfacing with a wear-resistant alloy comprising a steel shell filled with a powdered mixture consisting essentially of, by weight of the powder electrode strip, from 12 to 13% chromium, from 20 to 22% iron, from 0.2 to 0.3% graphite, from 1 to 1.2% ferrochromium having 0.6 to 0.8% carbon, 0.6 to 0.8% of crystalline silicon or silicocalcium with the silicon content being not less than 60& of the silicocalcium, from 14 to 16% manganese, from 0.6 to 1% titanium, from 2 to 3% titanium dioxide and the balance is the iron represented by the steel shell.
Claim 2
Dependent Claim
101 words
A powder electrode strip for surfacing with a wear-resistant alloy comprising a steel shell filled with a powdered mixture consisting essentially of, by weight of the powder electrode strip, from 12 to 13% chromium, from 20 to 22% iron, from 0.2 to 0.3% graphite, from 1 to 1.2% ferrochromium having 0.6 to 0.8% carbon, 0.6 to 0.8% of crystalline silicon or silicocalcium with the silicon content being not less than 60& of the silicocalcium, from 14 to 16% manganese, from 0.6 to 1% titanium, from 2 to 3% titanium dioxide and the balance is the iron represented by the steel shell.
