抗张强度

For processing the high tensile metals:carbon stell common alloy stell,hard bronze forgeable castiron.etc.

加工高抗张金属:碳素钢、硬青铜和可锻铸铁等。

Properties determined by mechanical testing, such as yield strength, ductility, ultimate tensile strength, hardness, bendability, impact strength, etc.

由机械试验决性，如屈服、延展、极抗张、硬、弯曲性、冲等。
