1.渗碳钢的特性：钢是一种高强度的高档渗碳钢，归于系列合金结构钢，渗碳钢强度高于，塑性及耐性稍低，钢淬火回火后有杰出的归纳力学功能和低温冲击韧度，淬透性及力学功能比钢较高，与钢恰当，比钢稍低；钢渗碳淬火后具有较高的抗弯强度和耐磨功能，渗碳后其剩余奥氏体含量较高，不宜直接淬火；钢的功能与日本合金结构钢附近，钢用于制作要求外表硬度高、耐磨功能好的重要渗碳件，如齿轮、凸轮轴连杆、销等；钢热加工功能杰出，正火后切削加工功能好，切削加工性优于钢和钢，但磨削时易发生裂纹，焊接功能较差，钢合适于电阻焊接，焊前要恰当预热，焊后应及时回火。 steel is a kind of to Cr Mn Mo alloy steel. steel has than lower and . After and steel has good and and than to lower than steel; steel has and After it has high and wear and the of is high, so it is not to be ; the of steel is to that of alloy steel. Henan iron and Steel Co., Ltd. steel to be used for parts with high and good wear such as rods, pins, etc.; steel hot After the is than steel and but it is easy to and the is poor. steel is for . it be and in time.
