Materials of Metric Roller Chain Sprocket

The raw material of the Metric Roller Chain Sprocket should ensure that the gear teeth have sufficient strength and wear resistance.Carbon steel,alloy steel,etc.are commonly used materials.

Forged steel:This material(generally with a carbon content of 0.15-1.6%)has good toughness and impact resistance,and can be heat-treated or chemically treated to improve its performance.This method can improve the hardness of the tooth surface, making it more suitable for gear transmission of heavy-duty and precision machines. For example,if small sprocket teeth participate in meshing many times and are prone to wear,you can choose high tooth surface hardness

Cast steel:Cast steel has excellent mechanical strength and hardness.It can be annealed,normalized,etc.,and is generally used to make larger gears.At the same time,its good corrosion resistance makes it suitable for use in different environments

cast iron:Gray cast iron is relatively brittle and not impact-resistant,but its chemical composition is stable,so it resists gluing,and pitting corrosion,and is not easily deformed.Chain sprockets made of this material are generally used in applications with low speed and low power
