Based on the statistics and analysis on tensile strength of HP295(0.13~0. 18C
0.80~1.00Mn
≥ 0.015Nb
≥0.010Ti)hot rolled steel strip for gas bottle by using multiple regression analysis method
the linear equation of tensile strength gu of HP295 steel strip with carbon equivalent.Cop=C+0.2426Mn-0.353Si
strip thickness h and coiling temperature CT:04=499. 1Cp- 17.72h-0.728CT+836.68.Examination results showed that relative eror between calculated and measured value of tensile strength of HP295 steel strip was ≤8.67% to meet the requirement for calculated precision.
