In this study , the resistance to high impact , corrosion and abrasive wear was determined for low carbon high alloy steel , and for comparison , the high manganese steel and the medium carbon alloy steel are also tested 腐蚀磨损试验机的转速400转分。在不同的介质( ph 3 )和不同的时间内，对低碳高合金钢、高锰钢和中碳合金钢进行了冲击腐蚀磨损性能的研究。
Continuous casters are capable of producing square shape billet square billet , rectangle billet slab billet and round shape billet round billet , and the steel brands consist of common carbon steel , high carbon steel , low alloy steel , high alloy steel , stainless steel and etc 连铸机可生产方型钢坯方坯矩型钢坯板坯圆型钢坯圆坯。生产的钢种有：普碳钢高碳钢低合金钢高合金钢不锈钢等。
And we also discovered there is no decreasing of the hardness on the surface of cr12 steel . it is due to dispersion harden by plentiful of alloy carbide and decreasing of residual austcnitc . these research work should provide some useful references for technicians in practice . at last , the program was also introduced 但在高合金钢cr12中发现硬度回落现象并不明显，这是因为本身该钢种的激光加工硬化带硬度并不大，另外高合金含量产生的弥散强化以及残余奥氏体的减少也是硬度回落小的一个原因。
We discussed the behavior of corrosion - abrasion of the liner of wet - grinding machine in simulated metallurgical conditions . the results show that under the simulated slurry , the corrosion rate and the wear loss of the low carbon high alloy steel is better than the high manganese steel and the medium carbon alloy steel 实验表明，在模拟冶金矿山的实际工况条件下，低碳高合金钢具有优良的综合性能，寿命最长，是比高锰钢和中碳合金钢更适合冶金矿山的严酷工况条件的湿式磨机衬板新材质。
And with the increased test time , the superiority of the low carbon high alloy steel was well illuminated . the worn surfaces of the three steels show that the mechanism of the low carbon high alloy steel is impact abrasion , the high manganese steel is impact - corrosion , and the medium carbon alloy steel is the heaviest impact - corrosion 最后通过hitachi - x - 650扫描电子显微镜考察了低碳高合金钢、高锰钢和中碳合金钢试样的冲击腐蚀磨损表面形貌，并用olympus光学显微镜进行了光学金相分析，对这三种钢的磨损机理进行一定的探讨。
