Effects of Normalizing and Tempering Temperature on Mechanical Properties and Microstructure of Low Alloy Wear Resistant Steel Casting

Abstract:

Influences of normalizing and tempering temperature on mechanical properties and microstructure of steel casting were investigated in this paper. The results showed that as the normalizing temperature increased, tensile strength increased, while tensile stretch increased slowly at first and decreased at last. Steel casting got best comprehensive mechanical properties after a 970°C normalizing treatment. Normalized at 970°C and tempered at the rage of 500 °C and 550°C, steel casting got best comprehensive mechanical properties. The relation between mechanical properties and temperature was gotten using Matlab Software. The microstructure was ferrite and pearlite after normalizing, and tempered sorbite after high tempering.
