steel materials
Material standards define chemistry, mechanical properties, tolerances and delivery condition for plate, sections and hollow sections. They are the reference point for what a grade such as S355J2, A992 or Q355 actually guarantees, and for the impact toughness that governs thickness limits in cold conditions.
