GB/T 3077 15Cr3 alloy steel is a commonly used medium carbon quenched and tempered steel. Its strength, hardness and wear resistance are higher than 15Cr steel. It is used in the manufacture of shaft, gear, connecting rod, connecting rod, spring, sleeve, etc.
15Cr3 alloy steel has good comprehensive performance, due to its moderate carbon content, good hardenability, no temper brittleness, good mechanical properties, good plasticity and stability. 15Cr3 alloy steel can be made into a variety of parts, such as axle parts, springs, bearings, gears, fork parts, and etc., which are widely used in various industries.
It can be used to make the parts of various machines, vehicles and mechanical devices with good performance and is suitable for various productions, such as the manufacture of agricultural machinery, automotive parts, machine-building industry and so on. The mechanical properties of 15Cr3 alloy steel can be improved by proper heat treatment, such as quenching and tempering, so that its strength, hardness and wear resistance can be better.
15Cr3 alloy steel can be used as a material for various welding parts. The welding performance of 15Cr3 alloy steel is good, which can ensure that the welding parts have good mechanical properties and performance. Due to its high wear resistance, 15Cr3 alloy steel is also suitable for the manufacture of surface hardening parts, such as rolling bearing rings and so on.
In addition, 15Cr3 alloy steel is also suitable for making medium and high pressure components (tubes, pans and cylinders). For example, when higher strength is required in pressure vessels, the 15Cr3 alloy steel can be selected with higher carbon content.
15Cr3 alloy steel also has good machinability. It is easy to machine, and the cutting speed is high. It is suitable for various machining parts, such as valves, pump parts and other machined parts requiring high surface finish.
15Cr3 alloy steel is widely used and has a wide range of applications. It can be used for various industries, such as automotive, machine-building, engineering and manufacturing industry. And it has good comprehensive performance, so it can meet the requirements of different production conditions for material selection.
