材料牌号: A29 4145
标准：A29/A29M (2005) 热锻及冷加工碳素钢和合金钢棒
国家与地区： USA
钢组： 结构钢
化学成分 (%)
C 0.4300 － 0.4800
Mn 0.7500 － 1.0000
P ≤ 0.0350
S ≤ 0.0400
Si (*) 0.1500 － 0.3500
Cr 0.8000 － 1.1000
Mo 0.1500 － 0.2500
＊Si Silicon may be specified by the purchaser as 0.10 % maximum. The need for 0.10% maximum generally relates to severe cold-formed parts
