Hard chrome plated Rods CK45, 4140

4140 hard chrome plated rod is a kind of high strength hard chrome plate bar made of material SAE 4140 steel bar. Our factory is a leading China 4140 chrome plated rod supplier, we manufacturer and supply a broad range of hard chrome plated 4140 steel bars, from metric size 6mm to 760 mm (imperial inch size 1/4″ to 30″).

What is 4140 steel?

Steel 4140 is AISI standard grade, it is a kind of alloy structural steel, equivalent to China standard GB 42CrMo.

4140 steel is a type of low alloy steel that is commonly used in various industries, including construction, manufacturing, and the oil and gas industries. It is made up of chromium, molybdenum, and manganese, and is known for its toughness, strength, and high resistance to impact and abrasion. It is also easy to forge, machine, and heat treat, making it a versatile material for many applications. 4140 steel is commonly used to make various products such as shafts, gears, bolts, and other machine components, as well as for making drill collars, tool joints, and heavy-duty machinery components.

The SAE 4140 alloy steel boasts high fatigue strength and low sensitivity to notches, with excellent low-temperature impact toughness and no significant temper brittleness. It is primarily used in the quenched and tempered state to manufacture parts that are subjected to high stress and impact loads, including hydraulic cylinder rods, pneumatic cylinder rods, the transmission eccentric shafts of horizontal forging machines, and crankshafts of forging presses.

4140 Chrome Plated Rod: Product Descriptions

The 4140 Chrome Plated Rod is manufactured by using high-quality SAE 4140 steel bar, which is then polished and ground to a high precision with centerless grinding. This rod is then plated with a minimum thickness of 20 microns (0.0008 inches) or 25 microns (0.001 inches) of chrome, which provides excellent corrosion resistance and a gleaming, reflective appearance. The 4140 Chrome Plated Rod is highly sought after by hydraulic and pneumatic industries due to its high yield strength and tensile strength and is commonly used for applications that require these properties.
