This group of UNE standard specifications covers carbon and alloy steels, plates for boilers and other pressure vessels, sheets and strips, high-strength low-alloy steels, heat-treatable steels, hot and cold-rolled plates for cold forming, and non-alloy steels. Steel casting specifications call out the standard properties for pressure purposes. The group of standards for tool steels, stainless and heat resisting steels is also presented.
Review of UNE Standards for steel consists of 3 volumes. It contains formally approved UNE standard classifications, guides, practices, specifications, test methods and terminology and related material such as proposals.
Covers:
The following data is given for each standard: standard number, grade, chemical composition and mechanical properties (yield point, tensile strength, notch toughness). When deemed useful, steel type, manufacturing method, thickness of plate heat treatment and other data are described.
