42CrMo Alloy Steel Cast Iron Sheave Pulley Wheel High Quality Crane Wheel

1. Crane wheel forgings are usually made of high-strength metal materials. Common materials include the following:

(1) Alloy steel: Alloy steel is a steel material whose properties are improved by adding alloy elements. Common alloying elements include chromium, nickel, molybdenum, etc. Alloy steel has excellent strength, hardness and wear resistance, making it suitable for crane wheels that can withstand high loads and harsh working conditions.

(2) Carbon steel: Carbon steel is a steel with a high carbon content. It has good strength and rigidity, and can obtain good hardness with appropriate heat treatment. Carbon steel is relatively cheap and widely used in the manufacture of crane wheels.

(3) High alloy steel: High alloy steel is steel containing a higher proportion of alloy elements (such as chromium, nickel, molybdenum, titanium, etc.). High alloy steel has higher strength, corrosion resistance and wear resistance, and is suitable for crane wheels that withstand high temperatures, corrosion or special working conditions.

(4) Stainless steel: Stainless steel is a metal material with good corrosion resistance, and the main alloying element is chromium. Stainless steel has good strength, wear resistance and corrosion resistance, and is suitable for crane wheels used in humid and corrosive environments.

2. The following are some common steel grades suitable for the manufacture of crane wheel forgings:

(1) 45# steel (GB 45, ASTM/AISI 1045): 45# steel is a carbon structural steel with moderate strength and toughness. It is more commonly used under medium load and general working conditions.

(2) 42CrMo alloy steel (GB 42CrMo, ASTM/AISI 4140): 42CrMo steel is a low-alloy quenched and tempered steel with high strength and hardness, as well as good toughness and wear resistance. Suitable for crane wheels withstanding high loads and harsh working conditions.

(3) 34CrNiMo6 alloy steel (EN 34CrNiMo6, ASTM/AISI 4340): 34CrNiMo6 steel is a high-strength low alloy steel with high strength, hardness and toughness. Suitable for crane wheels requiring higher strength and greater wear resistance.

(4) 30CrNiMo8 alloy steel (EN 30CrNiMo8): 30CrNiMo8 steel is a high-strength low-alloy steel with good strength and toughness. It is suitable for crane wheels with medium to high loads and high toughness requirements.
