Metallic materials — Steel — Method of test for the determination of brittle crack arrest toughness,...
This document specifies a test method for the determination of brittle crack arrest toughness.
It is applicable to ferritic steel base metals exhibiting ductile to brittle transition behaviour. Applicable materials are rolled steel plates. It is intended for materials with a tensile strength of 950 MPa or less and a test piece thickness of 200 mm or less. The range of arrest temperatures is…
High yield strength steel plates and wide flats for cold forming — Delivery conditions
This document specifies the requirements for weldable high yield strength plates and wide flats for cold forming.
It does not apply to weldable structural steels, whether or not of special quality, which are covered by other International Standards, namely:
— structural steels: ISO 630 (all parts);
— high yield strength flat steel products: ISO 4950-1, ISO 4950-2 and ISO 4950-3…
