Eureka Colormold (Modified P20) Eureka Colormold is used to repair many types of P-20 tools and dies, whether they are die casting dies or plastic injection molds. It is often used for high strength joining of low alloy steels and Chrome Moly steels. Eureka Colormold can also be used to repair the higher alloy steels like H-11, H-12 and H-13 when machining is a prime requisite. Eureka Colormold weld deposits are a low alloy (chrome/moly) , which is similar in chemistry to P-20. Except that Carbon levels are intentionally held low to obtain hardness values in the low 25-35 HRC range as welded. At this hardness level, the deposits have the similar etching, graining, and color match characteristics as P-20 in the low 30 HRC range.

Eureka 31 A.I.S.I. Type H-13 Eureka 31 is for the welding of H-11, H-12, and H-13 hot work tools and dies. Eureka 31 is an excellent choice for press forging type dies where high heat and abrasion are encountered. It is highly resistant to heat checking when subjected to alternating heating and cooling cycles. Several high volume forgings that demand the ultimate in weld metal mechanical properties for the forging industry are connecting rods, hand tools, sleeve yoke, and cam shafts. These applications are relatively shallow and for the most part small. Other forged products would include earth moving equipment and farm implements such as pipe wrenches, crankshafts, hooks, and cam rings. Eureka 31 is an A.I.S.I. type H-13 hot working tool steel alloy that is extremely tough. This alloy displays excellent retention of hardness at elevated temperatures, yielding excellent abrasion resistance. It also displays good impact resistance imparting good notch toughness and has moderate wear resistance. Eureka 31 has an as welded hardness of 49 – 54 HRC.

Eureka 71M A.I.S.I. Type O-1 Eureka 71-M Electrodes are excellent for repair of damaged tools and dies in the oil hardening class, especially those of Manganese – Chromium types. Also good for the repair of existing oil hardened tool steels where the deposit must be annealed to facilitate machining and then be hardened and tempered for service use. Compositely fabricated dies utilizing a mild or medium carbon base metal and facing with Eureka 71-M on the work surfaces does result in lower tooling costs. Use on flange dies or form dies where only moderate abrasion is encountered. Eureka 71-M Electrode deposits are typical of an A.I.S.I. O-1 oil-hardening grade of tool steel. Weld deposits have as welded hardness range of 50- 60 Rockwell “C”. The hardness is highly dependent on preheat temperature, length of time welding, and cooling rate. The composition will respond to the full anneal and hardening cycle of A.I.S.I. O-1 to facilitate machining and re-hardening. This electrode displays excellent toughness and shock resistance with moderate wear characteristics. Stick Electrodes and Micro Tig Rods Download Here Download Here
Eureka 72 A.I.S.I. Type H-12 Eureka 72 is used for repairing or building of hot and cold trim and shearing dies, punches, extrusion dies and die casting dies. It is an excellent choice for press forging dies where high heat and abrasion are encountered. A typical application is the automobile connecting rod forging. High volume forgings that demand the ultimate in weld metal mechanical properties would be connecting rod, sleeve yoke, and hand tools. These applications are relatively shallow and usually high production. Other forged products would include earth moving equipment and farm implements, hooks and lever brake bands and other shallow impressions, such as hand tools, pipe wrenches, and crankshafts. Eureka 72 is a H-12 hot working tool steel alloy. It has excellent hot hardness, wear resistance and displays reasonable impact resistance. The as welded hardness is 50 – 55 HRC Stick Electrode, Solid MIG Wire, TIG Rods, Metal Cored Wire, Flux Cored Wire, and Micro Tig Rods Download Here Download Here
Eureka 74 A.I.S.I. Type S-7 Eureka 74 is recommended for welding A.I.S.I. S-7 tool steel, however, because its weld deposits can be tempered to various hardness values, it can also be used to repair other shock-resisting grades plus many types of water-hardening tool steel. Eureka 74 works exceptionally well on metal stamping blank trim and pierce dies where edge chipping causes burr on parts. Eureka 74 is an ideal electrode for building cutting edges on composite cold and hot trim sections and punches. Eureka 74 is a A.I.S.I. type S-7 shock resisting tool steel alloy. The as welded hardness of the deposits will typically be 55–60 HRC which can be tempered to lower hardness when necessary. This alloy works well in cutting or shearing environments at room temperature due to its unique ability of having high strength and being tough.

Eureka 88 A.I.S.I. Type H-19 Eureka 88 is used on hot punches and trim dies, hot extrusion dies, hot press forging dies and forging die inserts. It is used in areas where severe heat and abrasion will be encountered. Some forged dies would be hand tools, gears, discs and connecting rods. This alloy performs well in shallow impressions and is often use as an overlay or hard facing alloy. Eureka 88 has an as welded hardness of 55 – 60 HRC. The weld deposits are very resistant to wear at elevated temperatures, display good thermal fatigue resistance, and retains good hot hardness. This alloy is an A.I.S.I. type H-19 hot work tool steel containing high levels of Chromium, Cobalt, Tungsten, and Vanadium.
