抗张强度

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

加工高抗张的金属: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.

由机械试验决定的特性，如、延展、极抗张、硬、性、冲击等。
