Cast steel wear-resistant material

"The Grader blade is made of cast steel wear-resistant material. The Grader blade is made of cast steel wear-resistant material. The effect of different heat treatment processes on the microstructure and mechanical properties of the cast Grader blade material. A normalizing or annealing preheating treatment before normalizing can improve the strength and toughness of the cast steel material for the Grader blade. After normalizing, 300 ℃ tempering heat treatment Grader blade material has high strength and impact toughness, and the heat treatment structure It is lath Bainite ferrite and residual austenite, and tempering brittleness occurs at 500 ℃.
