8 welding-alloys.com Tool steels Product Welding process Standard diameters [mm] AISI nearest correspondance EN 14700 standard Description and applications ROBOFIL M 700 -G 1.2 - 1.6 - High-strength alloy deposit with good toughness. Used for joining and repair of high strength or low and medium alloyed steels. Applications: Build-up prior to hardfacing. HARDFACE 40 -G 1.2 - 2.4 T Z Fe3 Medium alloyed bainitic steel deposit. Suited for the repair and rebuilding of forging dies. Offers a crack-resistant deposit with excellent resistance to low abrasion and moderate impact. Applications: Rebuilding die and sow blocks, rams, die holders. HARDFACE 45 -G 1.2 - 2.4 P20 T Fe2 Bainitic alloyed steel offering a crack-resistant deposit with a similar chemical analysis and matching colour to AISI P20 tool steel. HARDFACE 45 is fully compatible when polishing or etching is required. Can easily be used on lower-grade base metal to provide better wear performance. Applications: Casting dies, plastic injection moulds. HARDFACE 45W -G 1.2 - 2.4 T Fe3 HARDFACE 50W is a martensitic alloyed steel compatible with AISI H11, H12, and overalloying the H13 tool steels, guaranteeing high performance. The high content of tungsten, vanadium, molybdenum, and chromium makes this wire highly resistant to temperature and thermal fatigue when subjected to heating and cooling cycles. Withstands high temperatures without softening for consistent wear resistance. HARDFACE 45W is the low carbon equivalent product with low cracking sensitivity, making it suitable for rebuilding and/or buffering on very large components. Applications: Shallow impressions, hot and cold trim dies, shearing dies, extrusion dies, plastic injection moulds, punches. HARDFACE 50W -G 1.2 - 2.4 H11 T Fe3 H12 H13 HARDFACE 55WCO -G 1.2 - 2.4 H19 T Z Fe3 HARDFACE 55WCO is fully compatible with AISI H19 hot work tool steel. This weld metal provides excellent hot hardness combined with abrasion resistance. Applications: Shallow press dies, hot punches, trim dies. HARDFACE DCO -O 1.6 - 2.4 T Z Fe3 Special martensitic alloyed steel deposit offering similar performance to cobalt based alloys. The Fe-Cr-Co-Mo welding deposit is especially suited to resist metal-to-metal wear, oxidation, and corrosion at temperatures up to 600 °C. Economic alternative to cobalt based alloys. Applications: Hot stamping punches, press dies, casting rollers. -G 1.2 - 2.4 -S 2.4 - 3.2 HARDFACE 50Cr -G 1.2 - 2.4 T Z Fe8 Martensitic alloyed steel deposit. High strength and good toughness. Outstanding resistance to hot oxidation thanks to the high chromium level. Preferred solution for the lower half of impressions (buffer layer). Applications: Connecting rods, crankshafts and yokes. HARDFACE 55Cr -G 1.2 - 2.4 T Fe3 Martensitic alloyed steel deposit. High strength and outstanding resistance to hot oxidation due to its high chromium content. Additionally, the inclusion of vanadium and tungsten enhances its resistance to heat checking. The welding deposit is advantageous for intricate impressions where toughness is required. Applications: Shallow hammer dies, press dies. HARDFACE 60Mo -G 1.2 - 2.4 M2 T Fe4 Martensitic alloyed steel deposit giving a near-matching AISI M2 high-speed tool steel, maintaining high hardness even at high temperatures. The welding deposit remains hard, giving excellent properties on cutting edges, draw beads, and radii. Applications: Draw dies, shear blades, stamping dies.
