welding-alloys.com 17 Thermal fatigue Hot oxidation Corrosion Cutting Work hardening Machining Description and applications u u u u u Tubular wire for gas shielded arc welding giving a tough high speed steel deposit (precipitated fine carbides in a martensitic matrix). Exceptional wear resistance in cold cutting operations. Keeps its properties at temperatures up to 600°C (hardness may be increased to ~65 HRC after tempering for 2 hours at 500°C). Applications: cold shearing blades, machine tools, milling cutters, knives and wire guides. u u u u u Martensitic alloyed steel providing very good resistance to metal-to-metal and low stress abrasive wear. The higher the carbon content, the better the resistance to heavy impact and compressive stresses. HARDFACE W provides a hard deposit that keeps its properties over a long period of exposure to temperatures up to 500°C. HARDFACE W is slightly overalloying AISI H12 tool steels. HARDFACE WLC has low cracking sensitivity, which makes it suitable for rebuilding and buffering on very large components and alloyed steels. Applications: tooling for hot shearing, mill rolls, bells and hopper seats in blast furnaces, forging dies, deburring dies. u u u u u u u u u u u u Martensitic steel deposit with a medium hardness of 47 HRC. Exceptional oxidation resistance and toughness at high temperatures - up to 600°C. Applications: repairing and hardfacing of tools undergoing thermal shock, mechanical fatigue and adhesive wear. u u u u u u Martensitic welding deposit providing hardness in the range of 52 HRC. The high content of vanadium, tungsten, and chromium improves resistance to heat checking, and provides overall improvement to mechanical properties at elevated temperatures - up to 600°C. The welding deposit is an overalloyed version of AISI H13 tool steels. Applications: tooling for hot shearing, hot punches, hot extrusions dies, mill guides. uuuu u uu u u Special martensitic alloyed steel deposit offering similar performance to cobalt based alloys. This Fe-Cr-Co-Mo welding deposit is especially suited to resist metal-to-metal wear, oxidation, cavitation and corrosion at temperatures up to 550°C. u u u u u Copper coated and non-copper coated wires available. The higher the carbon content, the better the resistance to heavy impact and compressive stresses. ROBOTOOL wires are suitable for hardfacing parts undergoing metal-to-metal wear, compression and moderate impact loads at high temperatures. Applications: tooling for hot shearing, mill rolls, bells and hopper seats in blast furnaces, forging dies, deburring dies. u u u u u u u u u u Products with less harmful fumes or manufactured using a more sustainable process.
