FAQ's
What is EN 4130 steel and why is it widely used?
EN 4130, also known as AISI 4130, is a low-alloy steel containing chromium and molybdenum, which provide excellent strength, toughness, and weldability. It is valued for its high strength-to-weight ratio and fatigue resistance, making it suitable for demanding structural and mechanical applications. Due to its ability to be heat-treated for enhanced mechanical properties, EN 4130 is extensively used in aerospace, automotive, and oil & gas industries.
What are the chemical and mechanical properties of EN 4130 steel?
EN 4130 steel has a chemical composition that includes carbon (0.28–0.33%), manganese (0.40–0.60%), chromium (0.80–1.10%), and molybdenum (0.15–0.25%), along with small amounts of silicon, phosphorus, and sulfur. Mechanically, it offers tensile strength between 552–896 MPa and yield strength between 345–724 MPa, depending on the product form and heat treatment. With elongation up to 30% and hardness ranging from 150–260 Brinell, EN 4130 is strong, ductile, and highly versatile.
