这是美国的材料牌号，是易切削钢，类似20号钢，用Q235也可，本站可找到相应的对照资料

是含炭量为0.18%的低碳钢，一般对应我国材料为18#~20#钢。

CF应该表示是易切削钢

如果是美标切削钢的话打头是“11”，这个可能与宝钢（日本标准）SWRCH18A更接近一些。

与之相对应的是HR steel ，就是hot roll steel，
Any steel, alloy, low carbon or high that is rolled at the mill and left with the scaled finish and in the "as rolled" condition (not heat treated) is "hot roll steel",HR Steel or HR bar. In the past "mild steel" HR bar was SAE 1018-1020 but today common HR mild steel is structural grade ASTM A36 or similar.
