Validation of Methodology for Selecting Charpy Toughness Criteria for Old ThinLow Stength Steels

摘要

A methodology for selecting the minimum usage temperature for ferritic steels haspreviously been developed. The methodology is based on the statistical correlation between fracture toughness and Charpy-V, and has been verified for modern extra high strength steels. In this report, the methodology is verified experimentally with different test geometries for old (post Second World War quality) thin low strength steels.
