Free Interactive Tools
SteelOnTheNet provides free interactive tools designed for engineers, metallurgists, procurement specialists, analysts and anyone working with steel specifications and sustainability data. Our tools are built on industry-standard references and are regularly updated to reflect current practice across international markets.
Whether you need to identify the European equivalent of a North American steel grade, estimate the carbon footprint of a steelmaking process route, plan strip width requirements for large diameter pipe production, or look up gauge and size ranges for long or flat products, these tools provide a practical starting point backed by clear explanatory notes and appropriate caveats.

๐ Steel Grade Cross-Reference & Equivalent Finder
The steel grade cross-reference tool allows you to search for equivalent designations across the major international standards in use today. Enter any grade designation โ whether ASTM, EN, DIN, JIS, BS, ISO, GB or GOST โ and the tool returns all known equivalents in a compact summary row, with full detail available on expansion.
Coverage includes:
- Structural steels โ S235, S275, S355, S460, A36, A572, A992, A709 bridge grades
- Engineering / alloy steels โ 4140, 4340, 8620, 1045, 1018, 4130 and more
- Stainless steels โ austenitic, ferritic, martensitic, duplex (2101, 2304, 2205, 2507) and precipitation hardening
- Tool steels โ cold work (D2, O1, A2), hot work (H11, H13, H21), shock resisting (S1, S5, S7), plastic mould (P20, P21/NAK80, Stavax)
- High speed steels โ full T-series and M-series coverage including M2, M35, M42, T15
- Bearing steels โ 52100/100Cr6/ะจะฅ15, carburising grades, M50 aerospace bearing
- Spring, pipe, automotive AHSS, aerospace and nuclear grades
- GOST (Russian/CIS) equivalents across all categories, with appropriate caveats
โ Steel Production Emissions Calculator
The emissions calculator estimates Scope 1 and Scope 2 carbon emissions for steel production based on your selected process route. It covers the full range of primary and secondary steelmaking routes in use globally, and allows emission factors to be overridden with site-specific data where available.
Process routes covered:
- BF/BOF (blast furnace / basic oxygen furnace) integrated route
- EAF (electric arc furnace) โ 100% scrap or scrap/DRI blend
- DRI production routes โ coal-based, natural gas-based and hydrogen-based
- Induction furnace
- Secondary steelmaking โ ladle furnace, continuous casting, ingot casting
- Rolling and finishing โ flat products (HRC, CRC, galvanised, coated, tinplate), long products and tubular products
Grid carbon intensity is adjustable by region to correctly reflect Scope 2 emissions for EAF and other electricity-intensive processes.
๐ซ Large Diameter Pipe Planner
The large diameter pipe planner is a practical engineering tool for pipeline and tube mill professionals. It solves in both directions: derive the pipe OD achievable from a given strip or coil width, or calculate the strip width required to produce a target pipe OD.
Pipe types covered:
- ERW (electric resistance welded) โ longitudinal seam; tight, predictable OD/strip relationship
- LSAW (longitudinal submerged arc welded) โ plate-formed; larger diameter range with forming allowance
- HSAW (helical/spiral submerged arc welded) โ strip-fed spiral weld; variable OD achievable from a fixed strip width by adjusting the helix angle
Outputs include pipe OD or strip width (depending on solve direction), wall thickness, weight per metre, and lb/ft โ available in both metric and imperial units.
๐ Steel Long Product Size Guide
The long product size guide covers the full diameter and cross-section range of steel long products, from fine wire (0.04mm) through wire rod, rebar, cold drawn bar, merchant and special bar, primary rounds, structural sections, rail, and the semi-finished products billet and bloom.
