20CrMnTi-GB/T 3077-2015 Alloy Round Steel Bar Krobo Steel

The main characteristics and application areas of 20CrMoTi round steel

1)Strength and hardness: 20CrMoTi round steel has high yield strength, tensile strength and hardness, and can withstand large static and dynamic loads.This makes it very suitable for manufacturing parts that require high strength and wear resistance.


2)Heat treatment performance: 20CrMoTi round steel has good heat treatment performance, and its structure and performance can be adjusted by heat treatment methods (such as normalizing, quenching, and tempering) to meet specific engineering requirements.


3)Corrosion resistance: Due to the chromium content, 20CrMoTi round steel has good corrosion resistance and performs well in some applications with corrosive environments.


  • Application areas: 20CrMoTi round steel is widely used in the manufacture of high-strength and high-load parts and mechanical components such as construction machinery, automobile transmission parts, ship parts, oil drilling rigs, agricultural machinery, etc.
