Mechanical Properties

Tensile testing is performed in the transverse direction in accordance with ASTM A20. Specimens for tensile testing are prepared from material in the condition specified for plate use such as as-rolled, normalized, or post weld heat treated. The required tensile property requirements are tablulated below:
