苏联乌克兰特钢研究所研究了低温回火后的CT3ПС钢板的性能。在生产实践中,往往有采用高强度和一定塑性的冷轧薄钢板冲制零件和制品。苏联一般采用标定性能:б_b=500～700N/mm~2,δ_10≥17％的09Г2、14Г2、17ГС、25ХГСА、30ХГСА等钢种。由于合金元素的短缺,不可能都采用合金钢或低合金钢板。乌克兰特钢研究所试验采用厚度为3.0mm的CT3ПС(0.17％C;0.37％Mn;0.13％Cr;0.1％Ni;0.01％Si;0.028％S;0.009％P;0.14％Cu;0.02％Al)热轧薄钢板作为轧材,在连续式四机架薄板轧机上冷轧到1.2毫米(终轧温度为870～880℃,卷板温度
The Ukrainian Special Steel Institute of the Soviet Union studied the properties of CT3ПС steel after tempering at low temperatures. In production practice, often have the use of high strength and a certain degree of ductility of cold-rolled steel sheet punching parts and products. The Soviet Union generally uses the calibration performance: б_b = 500 ~ 700N / mm ~ 2, δ_10 ≥ 17% 09Г2,14Г2,17ГС, 25ХГСА, 30ХГСА and other steel species. Due to the shortage of alloying elements, it is impossible to use alloy steel or low alloy steel plate. Ukrainian Special Steel Institute tests using CT3ПС (0.17% C; 0.37% Mn; 0.13% Cr; 0.1% Ni; 0.01% Si; 0.028% S; 0.009% P; 0.14% Cu; 0.02% Al) The hot-rolled steel sheet was rolled as a rolled material and was cold-rolled to 1.2 mm in a continuous four-stand plate mill (finish temperature 870 to 880 ° C, coiling temperature
