ลองใช้Alloy Comparator
Compare two alloys side by side — mechanical properties, ratings, composition, and best use cases.
ลองใช้Weldability Checker
Check if an alloy is weldable and get carbon equivalent (CE) analysis for steel grades.
ลองใช้Corrosion Resistance Finder
Find alloys that resist specific corrosive environments — saltwater, acids, high temperature oxidation, and more.
ลองใช้Hardness Converter
Convert between Brinell (HB), Rockwell (HRC/HRB), Vickers (HV), and approximate tensile strength using ASTM E140.
ลองใช้Stress-Strain Calculator
Calculate engineering and true stress-strain from force, area, and elongation measurements.

Calculate dimensional change due to temperature. Input length, CTE, and temperature change.
ลองใช้Beam Deflection Calculator
Calculate maximum deflection for simply supported and cantilever beams with common load cases.
ลองใช้Fatigue Life Estimator
Estimate fatigue life (cycles to failure) using Basquin's equation from stress amplitude and material constants.
ลองใช้Metal Weight Calculator
Calculate the weight of metal shapes — plate, round bar, tube, square bar, and hex bar — from dimensions and density.
ลองใช้Carbon Equivalent Calculator
Calculate carbon equivalent (CE) for steel weldability assessment using IIW and Pcm formulas.
ลองใช้Strength-to-Weight Calculator
Calculate specific strength (strength-to-weight ratio) for material comparison in weight-critical applications.
ลองใช้Bolt Torque Calculator
Calculate recommended tightening torque for bolts based on size, grade, and lubrication condition.
ลองใช้Engineering Unit Converter
Convert common engineering units: MPa to ksi, mm to inches, g/cm³ to lb/in³, and more.
