For Stainless Steels Alloys

LoTherme-475

Low heat input, universal, high strength, high alloy electrode for crack-free welds.

Characteristics

LoTherme-475 is specially designed for highly favorable for producing welds that have complete freedom from hazards of cracking on a wide variety of similar and dissimilar materials. It operates in all conventional welding positions. Extremely low spatter. Easily detachable slag. Very smooth weld finish, which takes a high polish.

Applications

LoTherme-475 is ideally suited for high strength and overlays subject to services under wear, friction, impact, heat and corrosion on mild carbon, low alloy, molybdenum-vanadium spring, tool and die, stainless and dissimilar steels. Typical applications include welding on pressure vessels, salt water pipelines, dies, tools, leaf and coil springs and similar parts and surfacing hot dies, points and crossing, gear teeth, forged shafts, earth moving equipment and machine parts.

Typical Mechanical Properties Of All Weld Metal

Ultimate Tensile Strength : 830 MPa

Elongation (L=4d) : 22%

Welding Technique

Ensure the electrodes are dry. Re-dry the electrode at 250°C for one hour before use. Clean the weld area completely free of oil, grease, paint, rust or any other foreign matter. Use low current, short arc and stringer beads. For certain high alloy tool steels preheating is recommended.

Current Conditions : DC(+)/AC
