What is 4140 steel?

Steel 4140 is AISI standard grade, it is a kind of alloy structural steel, equivalent to China standard GB 42CrMo.
SAE 4140 alloy steel has high fatigue strength and low notch sensitivity, high low temperature impact toughness, no obvious temper brittleness, and is mainly used in the quenched and tempered state. It is used to manufacture high-strength parts and parts with large cross-sections and other stress-bearing components under impact load. Such as high strength Hydraulic cylinder rods, penaumatic cylinder rods, the transmission eccentric shaft of the horizontal forging machine, the crankshaft of the forging press, etc.

Here below is the material specifications of steel grade SAE 4140.

Besides 4140 honed cylinder barrel tubes, we also produce 4140 chrome bar, this product is the cromo de varilla de los cilindros hidráulicos made of steel SAE 4140, which is mostly used to produce hydraulic piston rods.
