材料名称:合金结构钢 牌号:20Cr2Ni4A军工钢 特性及适用范围: 20Cr2Ni4A是优质合金钢,强度高,韧性及淬透性好。渗碳后不能直接淬火,以减少表层残余奥氏体。切削性及冷变形塑性一般。焊接性较差,焊前需预热到150℃左右,工时白点敏感性强,有回火脆性倾向。20Cr2Ni4A用于大截面渗碳件,如大型齿轮、轴类以及要求强度高、韧性好的调质零部件等。 20Cr2Ni4A 化学成份: 碳 C :0.17~0.23 硅 Si:0.17~0.37 锰 Mn:0.30~0.60 硫 S :≤0.03 磷 P :≤0.03 铬 Cr1.25~1.65 镍 Ni:3.25~3.65 力学性能抗拉强度 σb(MPa):1483条件屈服强度 σ0.2 (MPa):1292伸长率 δ5 (%):13 断面收缩率 ψ (%):57冲击韧性值 αk(J/cm2)75硬度 :434HB试样尺寸:某试料 热处理规范及金相组织:热处理规范:880℃油淬+780℃油淬,200℃回火。 热处理规范及金相组织:热处理规范:淬火:第一次880℃,第二次780℃,油冷;回火200℃,水冷、空冷。 交货状态:以热处理(正火、退火或高温回火)或不热处理状态交货,交货状态应在合同中注明。 20Cr2Ni4A(重特轧炼)|Φ12(轧材)淬火+精炼 军工钢 20Cr2Ni4A(重特轧炼)|Φ13(轧材)淬火+精炼 军工钢 20Cr2Ni4A(重特轧炼)|Φ14(轧材)淬火+精炼 军工钢 20Cr2Ni4A(重特轧炼)|Φ15(轧材)淬火+精炼 军工钢 20Cr2Ni4A(重特轧炼)|Φ16(轧材)淬火+精炼 军工钢 20Cr2Ni4A(重特轧炼)|Φ17(轧材)淬火+精炼 军工钢 20Cr2Ni4A(重特轧炼)|Φ18(轧材)淬火+精炼 军工钢 20Cr2Ni4A(重特轧炼)|Φ19(轧材)淬火+精炼 军工钢 20Cr2Ni4A(重特轧炼)|Φ20(轧材)淬火+精炼 军工钢 20Cr2Ni4A(重特轧炼)|Φ21(轧材)淬火+精炼 军工钢 20Cr2Ni4A(重特轧炼)|Φ22(轧材)淬火+精炼 军工钢 20Cr2Ni4A(重特轧炼)|Φ23(轧材)淬火+精炼 军工钢 20Cr2Ni4A(重特轧炼)|Φ24(轧材)淬火+精炼 军工钢 20Cr2Ni4A(重特轧炼)|Φ25(轧材)淬火+精炼 军工钢 20Cr2Ni4A(重特轧炼)|Φ26(轧材)淬火+精炼 军工钢 20Cr2Ni4A(重特轧炼)|Φ28(轧材)淬火+精炼 军工钢 20Cr2Ni4A(重特轧炼)|Φ29(轧材)淬火+精炼 军工钢 20Cr2Ni4A(重特轧炼)|Φ30(轧材)淬火+精炼 军工钢 20Cr2Ni4A(重特轧炼)|Φ32(轧材)淬火+精炼 军工钢 20Cr2Ni4A(重特轧炼)|Φ35(轧材)淬火+精炼 军工钢 20Cr2Ni4A(重特轧炼)|Φ38(轧材)淬火+精炼 军工钢 20Cr2Ni4A(重特轧炼)|Φ40(轧材)淬火+精炼 军工钢 20Cr2Ni4A(重特轧炼)|Φ42(轧材)淬火+精炼 军工钢 20Cr2Ni4A(重特轧炼)|Φ45(轧材)淬火+精炼 军工钢 20Cr2Ni4A(重特轧炼)|Φ48(轧材)淬火+精炼 军工钢 20Cr2Ni4A(重特轧炼)|Φ50(轧材)淬火+精炼 军工钢 20Cr2Ni4A(重特轧炼)|Φ52(轧材)淬火+精炼 军工钢 20Cr2Ni4A(重特轧炼)|Φ55(轧材)淬火+精炼 军工钢 20Cr2Ni4A(重特轧炼)|Φ60(轧材)淬火+精炼 军工钢 20Cr2Ni4A(重特轧炼)|Φ65(轧材)淬火+精炼 军工钢 20Cr2Ni4A(重特轧炼)|Φ75(轧材)淬火+精炼 军工钢 20Cr2Ni4A(重特轧炼)|Φ80(轧材)淬火+精炼 军工钢 20Cr2Ni4A(重特轧炼)|Φ85(轧材)淬火+精炼 军工钢 20Cr2Ni4A(重特轧炼)|Φ90(轧材)淬火+精炼 军工钢 20Cr2Ni4A(重特轧炼)|Φ95 (锻材)淬火+精炼 军工钢 20Cr2Ni4A(重特轧炼)|Φ100(锻材)淬火+精炼 军工钢 20Cr2Ni4A(重特轧炼)|Φ105(锻材)淬火+精炼 军工钢 20Cr2Ni4A(重特轧炼)|Φ110(锻材)淬火+精炼 军工钢 20Cr2Ni4A(重特轧炼)|Φ115(锻材)淬火+精炼 军工钢 20Cr2Ni4A(重特轧炼)|Φ120(锻材)淬火+精炼 军工钢 20Cr2Ni4A(重特轧炼)|Φ125(锻材)淬火+精炼 军工钢 20Cr2Ni4A(重特轧炼)|Φ130(锻材)淬火+精炼 军工钢 20Cr2Ni4A(重特轧炼)|Φ140(锻材)淬火+精炼 军工钢 20Cr2Ni4A(重特轧炼)|Φ145(锻材)淬火+精炼 军工钢 20Cr2Ni4A(重特轧炼)|Φ150(锻材)淬火+精炼 军工钢 20Cr2Ni4A(重特轧炼)|Φ155(锻材)淬火+精炼 军工钢 20Cr2Ni4A(重特轧炼)|Φ160(锻材)淬火+精炼 军工钢 20Cr2Ni4A(重特轧炼)|Φ165(锻材)淬火+精炼 军工钢 20Cr2Ni4A(重特轧炼)|Φ170(锻材)淬火+精炼 军工钢 20Cr2Ni4A(重特轧炼)|Φ175(锻材)淬火+精炼 军工钢 20Cr2Ni4A(重特轧炼)|Φ180(锻材)淬火+精炼 军工钢 20Cr2Ni4A(重特轧炼)|Φ185(锻材)淬火+精炼 军工钢 20Cr2Ni4A(重特轧炼)|Φ190(锻材)淬火+精炼 军工钢 20Cr2Ni4A(重特轧炼)|Φ195(锻材)淬火+精炼 军工钢 20Cr2Ni4A(重特轧炼)|Φ200(锻材)淬火+精炼 军工钢 20Cr2Ni4A(重特轧炼)|Φ210(锻材)淬火+精炼 军工钢 20Cr2Ni4A(重特轧炼)|Φ220(锻材)淬火+精炼 军工钢 20Cr2Ni4A(重特轧炼)|Φ230(锻材)淬火+精炼 军工钢 20Cr2Ni4A(重特轧炼)|Φ240(锻材)淬火+精炼 军工钢 20Cr2Ni4A(重特轧炼)|Φ250(锻材)淬火+精炼 军工钢 20Cr2Ni4A(重特轧炼)|Φ270(锻材)淬火+精炼 军工钢 20Cr2Ni4A(重特轧炼)|Φ280(锻材)淬火+精炼 军工钢 20Cr2Ni4A(重特轧炼)|Φ290(锻材)淬火+精炼 军工钢
