Steel Guides and Calculators for Buyers and Engineers
OneKaizen publishes the guides and tools our own team uses: a metal weight calculator, a Jominy hardenability estimator, a wire drawing reduction calculator and plain-language guides to bright bars and hot rolled vs cold rolled steel.
CALCULATORS
Free Steel Calculators
Each tool gives a fast estimate for early planning. Check final figures against the applicable standard and your mill test certificate.
Metal Weight Calculator
Work out the weight in kg of a round, square, hex or rectangular bar, or a sheet, in steel, cast iron or aluminium. Enter the size and length. The page shows the formula for each shape and a worked example.
Open calculator ↗02 / CALCULATORWire Drawing Reduction Ratio Calculator
Compare the starting and final cross-section areas to get the area ratio, for a round, square or rectangular final section. Useful when you plan a drawing or rolling reduction.
Open calculator ↗03 / CALCULATORJominy Hardenability Calculator
Enter a steel chemistry and see the estimated hardness in HRC at ten distances along a quenched Jominy bar, as a table and a curve. It is an estimate, not a substitute for the end-quench test.
