  9. 4130 and 4140 Heat Treatments - Industrial Heating

    For 4130 steel, the recommended heat treatment consists of heating to austenitizing temperature, typically 1600F (870C), followed by water quenching. Water quenching will achieve a higher as-quenched hardness than oil quenching. Tempering (reheating after quenching) will achieve the desired hardness range.

  12. Heat treating - Wikipedia

    Heat treatment provides an efficient way to manipulate the properties of the metal by controlling the rate of diffusion and the rate of cooling within the microstructure. Heat treating is often used to alter the mechanical properties of a metallic alloy , manipulating properties such as the hardness , strength , toughness , [1] ductility , and elasticity .

  13. AED Metals: 4130 Normalized vs. Annealed Sheet

    Both the Normalizing and Annealing of 4130 steel sheet is a heat treating process that changes microstructure of the material. The process of how to material is heated and cooled is what produces the two different material states.

  14. 4130 post heat treating welding | race-deZert

    Post heat is used after welding to reduce residual stresses but if you havent really put a bunch of heat into the surrounding metal then the weld and heat affect zone are resisting against the parent metal so this helps them relieve residual stress between the two. stress relief is similar to post heat just at different tempuratures typically below the lower transformation stage. basically speaking 4130 has a high carbon content therefore the need for heat treatment is much higher than mild heat treating 4130 process
