Elehard® 55-G

General Description

An all position rutile/basic coated electrode that produces a high carbon heat treatable martensitic deposit

Designed for operator appeal and weld quality

Excellent arc characteristics, good restriking and low spatter

The electrode can be used with drag or contact welding technique as well as out of position

Current type

AC/DC electr. +

Application

Elehard® 55-G produces a crack-free wear resistant deposit with a hardness of 55-57 HRc depending on dilution and number of layers. It is particularly suitable for applications involving sliding, rolling and metal to metal wear, combined with resistance to mild abrasion.

Typical applications include:

Crane and mine car wheels

Sprockets and gear teeth

Skip guides

Dredger buckets

Scrapper blades

Transfer tables

Cable sheaves
