The shear modulus (also known as the modulus of rigidity) for EN24 steel typically ranges between 80 to 85 GPa (gigapascals). EN24 is a high-strength alloy steel known for its excellent mechanical properties, including high tensile strength and toughness. The exact value can vary based on the specific heat treatment and processing of the material.
En8 is low carbon steel and it can be toughned. En24 is medium carbon steel and it is generally called forged steel.
the yield strength of EN8 material is 465MPa.

mechnical properties of hardened steel
EN24 is a high quality, high tensile, alloy steel . Usually supplied readily machineable in 'T' condition, it combines hightensile strength, shock resistance, good ductility and resistance to wear. EN24 is available from stock in round bar, flat barand plate.TYPICAL ANALYSISEN24C.Si.MnNi.Cr.Mo.0.40%0.30%0.60%1.50%1.20%0.25%Hardening:Heat uniformly to 823/850°C until heated through. Quench in oil.Tempering:Heat uniformly and thoroughly at the selected tempering temperature, up to 660°C and hold at heat for two hours per inch oftotal thickness. Tempering between 250-375°C in not recommended as this can seriously reduce the steels impact value.Stress Relieving:Heat slowly to 650-670°C, soak well before cooling the EN24 tool in a furnace or in air.Mechanical PropertiesHeatTreatmentTensileStrengthRm N/mm²YieldStressRe N/mm²a% on5.665ÖSoImpactIzod JImpactKCV JProofStressrp0.2HardnessHBSizemmT850/1000654134035635248/302>150≤250T850/1000680135450665248/302>63≤250U925/1075755124754740269/331>29≤100V1000/1150850124742835293/352>13≤63W1075/1225940114035925311/375>6≤29X1150/130010201034281005345/401>6≤29Z1550123551091125444>6≤29
The density of EN8 steel is approximately 7.85 g/cm^3.
Well, when it comes to welding EN24 steel, you'll want to use a welding rod that matches its strength and composition, like an E11018 electrode. Pre-heating the steel can help reduce the risk of cracking and improve the overall weld quality, especially for thicker sections. Just remember, take your time, breathe, and trust in your skills - you've got this!
