45th steel surface induction hardening - HAIRUITUO

The high temperature tempering of No. 45 steel after quenching, the heating temperature is usually 560~600 °C, and the hardness requirement is HRC22~34. Because the purpose of quenching and tempering is to obtain comprehensive mechanical properties, the hardness range is relatively wide. AISI 1045 Carbon SteelAISI 1045 steel is characterized by good weldability, good machinability, and high strength and impact properties in either the normalized or hot-rolled condition. AISI 1045 steel has a low through-hardening capability with only sections of around 60 mm in size being recommended as suitable for tempering and through-hardening.
