UNE 36-079-73 defines requirements for non-alloy and low-alloy steel semiproducts intended for rerolling. The standard covers symbolic and numerical designations, steel types and grades, deoxidation conditions, chemical composition, mechanical properties, impact toughness, bending requirements, surface condition, defect removal, delivery conditions, sampling, specimen preparation, heat treatment, tensile, impact, and bending tests, retesting, acceptance procedures, and required documentation.
The document includes requirements for grades A 33, A 37, A 42, A 44, A 50, A 60, and A 70, along with referenced UNE standards for steel classification, designation, testing, and general supply conditions.
Application Scope: Applicable to rolled steel semiproducts for general-purpose rerolling, including products supplied under agreed inspection, testing, and acceptance conditions.
