Chrome plated rods are the chief part of the hydraulic piston rods & penumatic Piston rods, which are widely applied in many industries, especially in the machinery industry, where almost all products are used. It is precisely because of the wide application of chrome plated rods that people pay more and more attention to the choice of materials for the production of chrome plated rods, because if the chrome plated rods are made of inferior steel, it will directly affect the service life of the product. And if you choose different production materials, the performance and characteristics of the chrome plated rods made by them are also different, so do you know what materials are commonly used for the production of chrome plated rods?
The popular steel materials for making chrome plated rods are as follows:
1. CK45 / SAE 1045 / C45 / 45# steel.
CK45 steel is known as SA1045, C45, C45E, 45 # steel also, they are defined in different standards of different countries, but they are actually with the same chemical composition and mechanical properties, so treated as the same material.
This material is a high-quality carbon structural steel. It has good hot and cold processing properties, good mechanical properties and high strength. CK45 steel is qualified if its hardness is greater than HRC55 after quenching and not tempering. After heat treatment and re-quenching, it can reach HRC42-46, which can not only have good mechanical properties, but also meet the hardness requirements of the surface. CK45 chrome plated bar is the most popular material of chrome plated rods, it is known as 1045 Varilla De Acero Cromado in America.
2. 42CrMo / 42CrMo4 / SAE 4140
42CrMo is an high strength German standard alloy steel, 42CrMo is also famous and broadly used in China, and in America, this material is known as SAE 4140, also very famous material.
42CrMo/SAE 4140 is a quenched and tempered alloy steel. After proper heat treatment, certain toughness, plasticity and wear resistance can be obtained. And after quenching and tempering, it can have good comprehensive mechanical properties, good low temperature impact toughness and low notch sensitivity. In addition, this steel is suitable for cyanidation and induction hardening in addition to quenching and tempering.

3. Gcr15.
GCr15 steel is a kind of high carbon chromium bearing steel with less alloy content, which has relatively high hardenability, and can obtain high and uniform hardness after heat treatment. When it is quenched and tempered at low temperature, it can have high hardness, uniform structure, good wear resistance and relatively high contact fatigue performance, and it is sensitive to the formation of white spots and has tempering brittleness.
4. 27SiMn
5. ST52 /ST52.3 /E355 / Q345
ST52 is known as E355, and in China, it is equal to steel grade Q345, while in America, SAE 1026 usually can be treated as same with ST52 /ST52.3.
Not many chrome plated bars are made of ST52/ST52.3, but this material is usely used to make chrome plated hollow bar.
6. Stainless steel 304.
304 stainless steel, which is a grade of stainless steel produced according to the American ASTM standard. 304 Stainless steel has relatively high corrosion resistance, and can have high plasticity and toughness at low temperature, room temperature and high temperature, as well as good cold forming and weldability. However, since its austenite has no phase transformation during heating, it cannot be strengthened by heat treatment, and can only be heat treated to improve the corrosion resistance of steel.
Skyline is one of the first class and professional China chrome plated bar suppliers & manufacturers, it can produce chrome plated bars with all the above materials.
