The results show that these semi-high speed steels can be hardened remarkably by secondary hardening to meet the hardness requirements of cold rolling. The secondary hardness of the tested steels is increased with the contents of alloying elements such as Mo, V, Si and changed with quenching temperature to show two peaks.

研究结果表明，新型半高速钢有显著的二次硬化效应，能满足冷轧工作辊的硬度要求；随Mo、V和Si等合金元素含量升高钢的二次硬度升高，随淬火温度升高钢的二次硬度出现两次峰值。

In this context, Baosteel announced in November the price policy, a general lowering of plate 400, down 400 ship plate, boiler plate container drop 500; mainstream products in the hot-rolled carbon down 400 yuan / ton, machinery and steel and other varieties of steel cut 500 yuan / ton; is 2.75-3.0mmSPHC price of 3942 yuan / ton; and the general drop in cold-rolled 400 yuan / ton, is now 1.0mmSPCC price of 4776 yuan / ton; hot-dip galvanizing is also generally down 400 yuan / ton.
