Based in Hyderabad, India, Dhruv Metals is a top producer and supplier of premium alloy steel AISI 4340 bars and rods, which are known for their remarkable strength, durability, and resistance to fatigue. These bars and rods are made to exacting mechanical and structural specifications using premium raw materials and precise forging techniques. Dhruv Metals serves a variety of industries, such as heavy engineering, oil and gas, automotive, aerospace, and defence. The company, which is well-known for its reliable quality, precise dimensions, and prompt delivery, is dedicated to offering customers in India and abroad long-lasting, high-performance alloy steel solutions.
The base elements of Alloy Steel AISI 4340 Bars/Rods are iron, molybdenum (0.20–0.30%), manganese (0.60–0.80%), chromium (0.70–0.90%), nickel (1.65–2.00%), and carbon (0.38–0.43%). These components improve toughness, wear resistance, and hardenability. The alloy has outstanding ductility and impact resistance, as well as a tensile strength of 850–1000 MPa and a yield strength of roughly 700 MPa. The mechanical performance of AISI 4340 in high-stress applications is further improved by its exceptional fatigue strength and good response to heat treatment procedures like quenching and tempering.
