Abstract: The analysis on elements content in 58 heats stainless steel 1Cr15Ni4Mo3N (/% : 0. 11 ~0. 16C, 0. 50 〜 1. 25Mn, W0. 70Si, 4. 0 ~5. 0Ni, 14. 5 ~ 15. 5Cr, 2. 3 ~2. 8Mo, 0. 05 ~0. IN) random sampling from φ60 ~90 mm bars are carried out, while the longitudinal mechanical properties of each heat products heat-treated with 1 070 ℃ 1 h, air cooling, 一70℃ 4 h cold treatment then 200℃ 2 h tempering are measured. The regression equations between the chemical composition and the mechanical properties of steel are obtained by statistic regression analysis.
