Steel calculators & tools
Free engineering tools for steel buyers and engineers: theoretical weight, carbon equivalent, hardness conversion and unit conversion. Results update as you type.
Grade comparison tool
Pick two or three grades and compare standards, composition, properties and heat treatment side by side.
Grade finder — filter by composition & properties
Search all grades by category, alloy content, tensile strength and hardness to shortlist the right steel.
Steel weight calculator
Theoretical weight for plate, round / square / hex / flat bar and pipe — pick a grade and its density is filled in from the database.
Carbon equivalent (CEV) calculator
CEV (IIW) and Pcm from a steel's chemical composition, with a weldability indication. Prefill any grade from the database.
Hardness converter
Convert between HRC, HV and HB for steels (SAE J417 / ASTM E140), with approximate tensile strength.
Unit converter
MPa ↔ ksi, °C ↔ °F, mm ↔ inch, kg/m ↔ lb/ft and kg ↔ lb.
