①A structure is usually defined first, followed by heat treatment (e.g., K+V). When the sequence is reversed, especially for steels such as 45S20, 45SPb20, and 60SPb20, the values to be complied with must be agreed upon.
②The minimum transverse elongation in a tensile test applies to steels 9Mn28, 9SMnPb28, 15S10, 10S20, and 10SPb20 in structural or heat-treated states U+SH and K+S.
③Round bars exceeding 50mm in diameter are generally supplied in a peeled condition rather than cold-drawn.
