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