EN19 Bars

Super Metal Manufacturing Co. is a leading manufacturer and exporter of premium-quality EN19 Bars, delivering high-strength alloy steel solutions to industries worldwide. With decades of experience in metallurgy and steel processing, the company has established itself as a reliable source for EN19 grade bars, offering exceptional performance in high-load and high-impact applications. The company maintains strict quality controls and compliance with global standards, making them a preferred supplier across multiple sectors.

EN19 Bars, also referred to as 4140 or 42CrMo4 in international standards, are chromium-molybdenum alloy steel bars known for their high tensile strength, ductility, and shock resistance. These properties make EN19 ideal for heavy-duty applications such as gears, shafts, axles, spindles, studs, bolts, and connecting rods. Super Metal supplies EN19 Bars in various heat-treated conditions like normalized, hardened and tempered, or annealed, depending on the application needs.


Super Metal offers EN19 Bars in a wide range of sizes—from 20 mm to 800 mm diameter—and in multiple forms such as round, hexagonal, square, or flat bars. Surface finish options include black, bright, peeled, or machined. These bars are manufactured as per BS 970 709M40, ASTM A29 4140, and DIN 42CrMo4 standards. Each bar is tested for dimensional accuracy, mechanical properties, and surface defects to ensure high performance and reliability.
