Material Selector
Input your requirements — strength, corrosion resistance, weight, and application — to get recommended alloys.
試してみるAlloy Comparator
Compare two alloys side by side — mechanical properties, ratings, composition, and best use cases.
試してみるWeldability Checker
Check if an alloy is weldable and get carbon equivalent (CE) analysis for steel grades.
試してみるCorrosion Resistance Finder
Find alloys that resist specific corrosive environments — saltwater, acids, high temperature oxidation, and more.
試してみるHardness Converter
Convert between Brinell (HB), Rockwell (HRC/HRB), Vickers (HV), and approximate tensile strength using ASTM E140.
試してみるStress-Strain Calculator
Calculate engineering and true stress-strain from force, area, and elongation measurements.
試してみるThermal Expansion Calculator
Calculate dimensional change due to temperature. Input length, CTE, and temperature change.
試してみるBeam Deflection Calculator
Calculate maximum deflection for simply supported and cantilever beams with common load cases.
試してみるFatigue Life Estimator
Estimate fatigue life (cycles to failure) using Basquin's equation from stress amplitude and material constants.
試してみるMetal Weight Calculator
Calculate the weight of metal shapes — plate, round bar, tube, square bar, and hex bar — from dimensions and density.
試してみるCarbon Equivalent Calculator
Calculate carbon equivalent (CE) for steel weldability assessment using IIW and Pcm formulas.
試してみるStrength-to-Weight Calculator
Calculate specific strength (strength-to-weight ratio) for material comparison in weight-critical applications.
試してみるBolt Torque Calculator
Calculate recommended tightening torque for bolts based on size, grade, and lubrication condition.
試してみるEngineering Unit Converter
Convert common engineering units: MPa to ksi, mm to inches, g/cm³ to lb/in³, and more.
試してみるMetallurgical Temp Converter
Convert temperatures between °C, °F, K, and °R with color reference for steel heat treatment.
試してみるDensity Converter
Convert density between g/cm³, kg/m³, lb/in³, and lb/ft³ for material specifications.
試してみるSteel Grade Identifier
Look up a steel grade designation to find its properties, equivalent grades in other standards, and common uses.
試してみるDrill & Tap Size Chart
Find the correct drill bit size for tapping metric and imperial threads. Includes tap drill and clearance hole sizes.
試してみるComposition Analyzer
Analyze an alloy's chemical composition. See element breakdown, identify the alloy family, and compare to specifications.
試してみるHeat Treatment Guide
Get heat treatment parameters for common steel grades — annealing, normalizing, quenching, and tempering temperatures.
