        5CrNiMo

        2019-10-31
        5CrNiMo
        詳細介紹:

        5CrNiMo鋼具有良好的韌性、強度和高耐磨性,屬熱作模具鋼。它在室溫和500~600℃時的力學性能幾乎相同。在加熱到500℃時,仍能保持住HB300左右的硬度。由于鋼中含有鉬,因而對回火脆性并不敏感。從600℃緩慢冷卻下來以后,沖擊韌性僅稍有降低。


        化學成份


        碳 C :0.50~0.60

        硅 Si:≤0.40

        錳 Mn:0.50~0.80

        硫 S :≤0.030

        磷 P :≤0.030

        鉻 Cr:0.50~0.80

        鎳 Ni:1.40-1.80

        銅 Cu:允許殘余含量≤0.30

        鉬 Mo:0.15~0.30


        硬度:退火,241~197HB,壓痕直徑3.9~4.3mm


        技術參數


        淬火后 :58

        淬火溫度℃ :830~860

        交貨狀態 :退火HB≤241

        冷卻劑 :油Oil

        5CrNiMo steel has good toughness, strength and high wear resistance, and is a hot work die steel. It has almost the same mechanical properties at room temperature and 500 to 600 °C. When heated to 500 ° C, it can still maintain the hardness of HB300. Because steel contains molybdenum, it is not sensitive to temper brittleness. After slowly cooling from 600 ° C, the impact toughness was only slightly reduced.
