Welding consumable used to produce non-magnetic welds or hard facings for drill strings or ship construction comprises a high strength iron-manganese-chromium welding alloy or a self-fluxing nickel-chromium hard facing alloy

摘要

A welding consumable comprises an antimagnetic high strength iron-manganese-chromium welding alloy or a self-fluxing nickel-chromium hard facing alloy of specified compositions. A novel welding consumable comprises an antimagnetic high strength iron alloy containing (by wt.) 20% Mn, 15% Cr, 0.3% Mo, 0.4% N and 0.03% C. An Independent claim is also included for a welding consumable for producing hard, wear resistant, self-fluxing nickel base hard facings, containing 25-40 wt.% Cr and optionally Mo to achieve a non-magnetic coating.
