Alloy material for carbon strong cooler ploughshare shovel for aluminum

The invention discloses an alloy material for a carbon strong cooler ploughshare shovel for aluminum. The alloy material comprises, by mass, 0.15-0.30% of C, 0.20-0.35% of Si, 0.35-0.75% of Mn, 12-18%of Cr, 2.5-3.5% of Mo, 0-0.040% of P, 0-0.030% of S, 0-0.030% of Ni, 0.8-1.2% of Cu and 76.8-83.9% of Fe. Compared with the prior art, by adopting the alloy material with the ingredients for manufacturing the carbon strong cooler ploughshare shovel for aluminum, the hardness and strength are both improved, the service life can be prolonged by four times, and the purpose is achieved. 本发明的目的在于公开种用于铝用炭素强力冷却机犁铧铲的合金材料，它包括如下质量百分比的成分：C:0.15-0.30％，Si:0.20-0.35％，Mn:0.35-0.75％，Cr:12-18％，Mo:2.5-3.5％，P:0-0.040％，S:0-0.030％，Ni:0-0.030％，Cu:0.8-1.2％，Fe：76.8％-83.9％；与现有技术相比，采用上述成分的合金材料制作铝用炭素混捏机犁铧铲，硬度和强度得到提高，使用寿命可提高4倍，实现本发明的目的。
