摘要
从化学成分、组织、力学性能(屈服强度Rel、抗拉强度Rm、延伸率A、屈强比Rel/Rm值)、应变硬化指数n值、塑性应变比r值等方面分析了CSP HP295的冲压性能特点,对今后包钢薄板品种发展方向提出建议。
Impacting and pressing properties of CSPHH295 have been analyzed in aspects of chemical composition, structures, mechanical properties ( Rel , Rm , A , Rel / Rm values), strain hardening index value and plastic strain ratio value of sheet metal CSPHP295, and suggestions for development of Baogang sheet metal variety in the future put forward,
