E195 机械性能

交货状态	抗拉强度 σ_b Mpa	屈服点 σ_s Mpa	断后伸长率或延伸率 δ %
+C	≥420	≥0.8σb	≥6
+LC	≥370	≥0.7σb	≥10
+SR	≥370	≥260	≥18
+A	≥290	≥0.5σb	≥28
+N	300~440	* ≥195	≥28

① +C=Cold drawn / hard(冷拔/硬化)；② +LC =Cold drawn / soft(冷拔/软化)；③ +SR=Cold drawn and stress relieved(冷拔并去除应力)；④ +A=Annealed(退火)；⑤ +N=Normalized(正火)
*For tubes with outside diameter ≤ 30 mm and wall thickness ≤ 3 mm the ReH minimum values are 10 MPa lower than the values given in this Table.
注：表中σs为上屈服强度ReH
