国外材料转化表2.pdf

Some Chinese standard material which performance is similar to the foreign material is listed below for reference for material substitution. 现将部分性能与下列材料性能接近的国内牌号列表如下,供材料转换时参考。 1. Ck45N As per the former drawing, the material “CK45” can be substituted by the CHINESE standard “45”. So, the material “Ck45N” can be substituted by “45 processed by heat treatment N” “Ck45N” 可用经正火处理的45 号钢代替。 2 ．C35 Note: steel to be used for mechanical purposes with machining features as shafts, bolts and so on. 2-1 C35 特性 performance for C35 材料化学成分 Chemical composition 钢号 P S Als Ti Cr Ni Mo 其它 C Si Mn Nb V Cu Designation ≤ ≤ ≥ ≤ ≤ ≤ Others C35 0.32~0.39 ≤ 0.4 0.5~0.8 0.045 0.045 0.4 0.4 0.1 材料机械性能 Mechanical properties 钢号 Designation 板厚 t 屈服强度σ MPa 拉伸强度 σ MPa 伸长率 δ ≥ % 面收缩率 ψ ≥ % 冲击吸收功A / J ≥ s b KV ≤ 16 430 630~780 17 35 C35 17~40 370 600~750 19 40 41~100 320 550~700 20 45 2-2 可对应国内牌号 corresponding Chinese standard 材料化学成分 Chemical composition
