Jis Scr440 Steel Round Bar For Machinery Manufacturing - China

JIS SCr440 steel round bar is a chromium steel specified in the Japanese Industrial Standard (JIS G 4105) and is classified as a structural steel with guaranteed hardenability.

Key Features:

* Compositional Characteristics: Containing approximately 1% chromium (Cr), this significantly improves the hardenability of JIS SCr440 steel round bar, meaning that even the core of larger cross-section parts can maintain good mechanical properties during heat treatment.

* Core Properties: After quenching and tempering, it exhibits excellent comprehensive mechanical properties—combining high strength and fatigue limit with good ductility and toughness.

* Machinability: Machinability is excellent in the annealed state.

After quenching and tempering, JIS SCr440 steel round bar exhibits a high hardness, making it difficult to cut, typically requiring grinding or the use of carbide tools.

Application Examples

JIS SCr440 steel round bar is widely used in the manufacture of high-strength, fatigue-resistant parts for medium-sized machinery, such as:

* Drive shafts, connecting rods, axles, and spline shafts for automobiles and tractors

* Gears, spindles, and worm gears for machine tools

* Gear teeth and drill bit joints for petroleum machinery

* High-strength bolts and nuts Songshun specialized in Special Steel for almost 20 years.
