Weld Star Weldstar Dual Core HF600-G MIG Wire 1.2MM - 15KG

Weldstar Dual Core HF600-G MIG Wire 1.2MM - 15KG Features and Applications Seamless high fill copper coated tubular wire for semi-automatic applications. Ideal for hardfacing components subject to abrasion and moderate impact. Unique welder appeal. Deposition rate increased by up to 20% when compared to solid wire. Martensitic weld metal contains finely dispersed hard carbides ensuring an optimal balance between abrasion, friction and impact resistance. Abrasion resistance at service temperatures up to 450°C. Preheat will be determined by the application and whether micro cracking in the deposit is acceptable. According to the base material preheating in the range 150°C - 300°C may be necessary. Precision layer wound for superior wire feeding characteristics. Typically used on bucket teeth, bucket lips, bulldozer blades, crusher jaws, scraper blades, chutes, pump housings, conveyor screws, slide plates, gear teeth, crusher hammers, drilling bits, ploughshares, reamers etc. Test Certificates can be found online @wilkinsonstar247.com    Standards EN ISO 14700 - T Fe2   Chemical Composition % (Typical) C% Mn% Si% P% S% Cr%  Ni% 0.5 1.2 0.6 0.010 0.013 5.7 0.05               Mo% Cu% Fe% Co% V% W%   0.80 0.10 Bal 0.006 0.010 <0.09     Hardness (HRC) Current Type Hardness - First Layer Hardness - Third Layer DC+ 52-55 54-57 DC- 55-57 57-60 Peak hardness in the range 50-62 HRC could be achieved in three layers.

Weld Star Weldstar Dual Core HF55-0 MIG Wire 15KG

Features and Applications Metal cored tubular wire for self-shielded metal arc hardfacing. High chromium cast iron deposit containing a high proportion of hard primary chromium carbides in a tough austenitic matrix. The deposit is suitable for hardfacing components subject to extremely severe abrasive wear and moderate impact. Relief checking is normal and does not affect the properties of the deposit. However it is recommended putting down only two layers unless impact loading is small. Multi-layer deposits are possible in specific applications. Precision layer wound for superior wire feeding characteristics. Typically used on gyratory crusher cones and mantles, catalyst pipes and valves, slurry pipes and valve bodies, dredge pump bodies, sand dredge parts, extruder screws, “barmac” crushers, mining and earthmoving equipment, blast furnace bells, brick muller tyres, crusher hammers and rolls, riddle plates, wear plates, drag line components, screw conveyors for cement, cone knives and shredders, etc Test Certificates can be found online @wilkinsonstar247.com    Standards EN ISO 14700 - T Fe15   Chemical Composition % (Typical) C% Mn% Si% P% S% 5.5 1.2 1.7 0.008 0.010           Cr% Ni% Mo% Fe% Nb% 28.0 0.15 0.04 Bal 0.020 Structure is primary carbides and eutectic carbides of the M7C3 type in an austenitic matrix.   Hardness (HRC) Current Type Hardness - Third Layer DC+ 58-64 Mechanical properties are approximate and may vary based on the heat, welding parameters and other factors.   Wear Type Suitability   Welding Parameters Ømm Current (A) Voltage (V) 1.20 mm 100-250 21-28 1.60 mm 160-320 24-30   Welding Positions EN ISO 6947 - PA
