Hardalloy 140 deposits a high chromium carbide alloy steel. It is an excellent general purpose alloy for high abrasion applications coupled with some impact. It maintains its wear resistance to a temperature of 1200°F and offers some corrosion resistance. Hardalloy 140 is designed for overlay on carbon, low alloy, or austenitic manganese base metals or a weld metal base of Hardalloy 32, Hardalloy 118, or Chrome-Mang. Some relief check will occur. The cracking is not detrimental to the wear properties of the deposit and provides some degree of stress relief for the weld metal

• Hardalloy 140 is an exceptionally smooth operating electrode with a quiet, stable arc
• It has good restrike characteristics and easily removed slag
• It produces a smooth, almost ripple-free bead surface
• It operates well on AC
• When welding vertical, the smaller diameters have better operating characteristics
• Can be used successfully by building a series of horizontal beads on a "shelf" using a weave technique
• 3.5 lb/hr at 120 amp deposition rate
• Physical state: cored wire, form: round wire, color: gray
