回答（1）：

TMCP(Thermo Mechanical Control Process:热机械控制工艺）即为控轧控冷状态交货正火一般在空气中自然冷却 2者工艺不同材质体现不尽相同。S460N欧标高强度板，强度高，特别是在正火或正火加回火状态有较高的综合力学性能。主要用于大型船舶，桥梁，电站设备，中、高压锅炉，高压容器，机车车辆，起重机械，矿山机械及其他大型焊接结构件。S460N执行标准：EN10025-3 同类别还有S460N、S460NL、S460Q、S460QL、S460QL1、S460M、S460ML.等牌号。

回答（2）：

区别主要是热处理工艺不同，TMCP和正火轧制指的都是钢板的热处理状态
TMCP一般指的是热机械轧制，正火轧制一般用N表示
外采纳，谢谢！
