简要阐述塔机用钢材的硬度和抗拉强度的换算问题,对两种力学试验的类似点和差别、影响钢材现场硬度值检测的因素、结合实际对换算的标准选择和换算局限性分别做以简要的讨论。
A brief account of the conversion of hardness and tensile strength of tower crane steel is made. The similarities and differences between the two kinds of mechanical tests, the factors that affect the on-site hardness testing of steel are analyzed. The standard selection and conversion limitations of the conversion are respectively Brief discussion.
