We use better mechanical qualities and precise production to make our AISI 4130 round bars operate under demanding situations.

AISI 4130 Round Bars

The intense chemical makeup of the 4130 alloy steel round bar contains manganese, carbon, chromium, and molybdenum. Although carbon content (0.28%) adds to exceptional hardness and wear resistance, chromium (0.80%) increases corrosion resistance and oxidation protection. Manganese (0.40%) increases toughness and durability; molybdenum (0.15%) improves strength and heat resistance. This unique combination guarantees exceptional performance from our CS 4130 round bars for various uses.

One of the key advantages of 4130 AISI round bars is their exceptional heat resistance. These bars are perfect for use when they need constant strength and minor deformation, as they keep stability under high temperatures. The alloy's excellent tensile strength, fatigue resistance, and chemical stability further guarantee dependability in essential parts such as structural elements, gears, and shafts.

Comparable mechanical and chemical qualities of the alloy steel 4130 round bar are those of worldwide counterparts, including EN19, 25CrMo4, and SCM430. Engineers extensively employ these bars to fabricate engine components, drilling tools, and aerospace fittings due to their remarkable machinability and weldability. Engineers and fabricators primarily choose these bars due to their versatility and consistent performance. Our first priorities at Piyush Steel are precision and quality so that every 4130 round rod meets exact industry standards. As a leading 4130 round bar supplier, we provide custom sizes to meet your project needs, heat treatments, and coatings.
