Thermal conductivity is a measure of the heat energy transferred through a material in a given time. The thermal conductivity of GB/T 3077 18CrMnNiMo steel is about 35.4 W/(mK). This thermal conductivity is considered quite high for a steel alloy, which is indicative of its good heat dissipation properties.

The specific heat capacity for GB/T 3077 30CrNiMo steel is about 462 J/(kg K). This indicates that the material is able hold a considerable amount of heat energy without undergoing substantial changes in temperature.

The mechanical properties of GB/T 3077 20CrMn steel, including its strength, ductility.
Strength: GB/T 3077 20CrMn steel is renowned for its high strength and ability to withstand loads and stresses. It has a tensile strength of over 500 MPa, and an ultimate tensile strength of 600 MPa. It's an excellent material for structures that must support heavy loads or experience frequent shock or impact.
Ductility: GB/T 3077 20CrMn steel has a high ductility and is highly malleable. It can be bent, cut, and pressed into a variety of shapes without cracking or breaking. This is critical for applications such as auto body parts and construction components, where the steel must be able to withstand constant mechanical stress without becoming brittle.

GB/T 3077 40-B is one of the most commonly used Chinese structural steels especially for low to medium strength applications. It is well suited for hot forming and cold forming, and it is often used for medium strength mechanical parts. Its tensile strength is from 370 to 500MPa and yield strength from 310 to 390MPa. GB/T 3077 40-B is widely used for the production of hot rolled steels for machine building, brakes and press components, crankshafts, gears, shafts for engines, hydraulic power units and parts for oil-field industry. It is also suitable for manufacturing heat-resistant parts, vehicle load components, shafts, and such.
