Known for its rigorous quality control and state-of-the-art production methods, Dang Steel guarantees that each AISI 4130 Bar adheres to international standards. Their products have earned a solid reputation in the automotive, aerospace, and engineering sectors for their durability and performance. By blending innovative technology with skilled craftsmanship, Dang Steel produces bars that boast excellent consistency, corrosion resistance, and mechanical strength, making them the go-to choice for manufacturers in search of premium alloy steel solutions.
Alloy Steel AISI 4130 Bars are primarily made up of chromium (0.8–1.1%), molybdenum (0.15–0.25%), and carbon (0.28–0.33%), along with iron and trace amounts of manganese, silicon, and phosphorus. This carefully balanced composition provides a mix of toughness, hardness, and tensile strength. Typically, AISI 4130 Bars show a tensile strength ranging from 560 to 690 MPa and a yield strength of 460 MPa, along with impressive fatigue resistance. They also have an elongation of about 25%, which offers enough ductility, while the steel remains easy to weld and machine. Heat treatment further boosts hardness and impact resistance, making these bars ideal for demanding applications.
