SAE 4340 chrome plated rod is a type of round steel rod used in many different industries, such as automotive, construction, aerospace, and especially telescopic custom hydraulic cylinder applications. It has a high tensile strength, so it will not deform when put under pressure. This steel also has a low carbon content, making it solid and durable but lightweight.
4340 steel is one of the most common grades of steel used for machine and manufacturing cylinders applications due to the excellent strength/weight ratio makes it a popular choice for many machinery, vehicles, and structures. The 4340 steel is a type of steel with high strength and toughness. The 4340 round bar Steel is also called “chrome molybdenum” because it has a higher content of chromium and molybdenum than other types of steel.
The SAE4340 cylinder round bar after hard chromed has a yield strength of about 100,000 psi, whereas the yield strength for other types of steel ranges from about 60,000 to 80,000 psi. As a professional SAE4340 chrome plated bar supplier, manufacturer,exporter in China, YUTONG INDUSTRY has more than 20 years production experience, we sell induction hardened chromed bar,hard chrome rod/shaft to customers and provide full range of technical support.
