5、产上需要一个比较准确 的硬度和强度的换算关系。实践证明， 金属材料的各种硬度值之间， 硬度值与强度值之间具有近似的相应关系。 因为硬度值是由起始塑性变形抗力和继续 塑性变形抗力决定的，材料的强度越高，塑性变形抗力越高，硬度值也就越高。仅供个人用于学习、研究；不得用于商业用途For personal use only in study and research; not for commercial use.Nur fur den pers?nlichen fur Studien, Forschung, zu kommerziellen Zwecken verwendet werden.Pour
