SteelAtlas: Steel Grades

SteelAtlas is a fast, offline reference for mechanical, materials and manufacturing engineers, students and technicians. Look up a grade, compare two materials, run a quick calculation, or read a worked guide — all without a network connection and without ads. WHAT'S INSIDE • 540+ materials — carbon and alloy steels, stainless, tool steels, cast irons, powder-metallurgy materials and non-ferrous alloys. Chemical composition, mechanical properties, heat-treatment data and equivalent international standards, each traceable to a listed reference. • Standards section — 12 standards bodies (EN/DIN, AISI/SAE, JIS, ISO, GOST, BS, IS and more), designation anatomy, key specs, and live links to the grades they cover. • Engineering calculators — fatigue (S-N / Goodman), press-fit interference, bolt preload and torque, thermal expansion, case-depth, unit and hardness conversion. Pure formulas, with the assumptions stated. • Compare — put two grades side by side: composition, properties, Jominy and tempering curves, and a plain-language read on whether one can substitute for the other. • Engineering Library — 57 practical articles, including in-depth guides on heat treatment, hardenability, surface hardening, fatigue and failure analysis, organised into task-led learning paths. • Universal search across materials, the library, standards and tools from one box. • English and Turkish. Light and dark themes. PRIVACY SteelAtlas works fully offline. It has no analytics, no advertising and no tracking, and makes no network requests. Your favourites, bookmarks, reading position and (optional) account are stored only on your device. NOTE SteelAtlas is an educational reference. Material and standard data should be verified against the governing standard and your own engineering analysis before use in design.
