Sagar Steel Corporation is a well-known enterprise of alloy steel round bar manufacturers that offer customers high-performance alloy steel round bars that are meant to be strong-wearing and that are hard to break. To become rough, tough, and hard, our steel bars are alloyed with quality resources such as chromium-molybdenum, nickel, vanadium, and manganese. The bars are utilized in the industries where the treatment is the most demanding, i.e., in power plants, refinery industries, oil field equipment, shafts and gears, and the forged components.
Our products and services comprise production and markets of round bars with alloy steels meeting the international standards such as ASTM A182, A335, and A479. The scope of our locations entails the provision of bars in different grades and includes, but is not limited to, EN19, EN24, 4140, and 4340 to all our B2B clients, such as OEMs, EPC contractors, and heavy engineering companies. Capabilities of custom length, heat treatment, precision machining, and surface treatment in the petrochemical, toolmaking, construction, and auto industries make us rapid, reliable, and the best to perform on time and with quality consistency on project specific needs of the customer.
Versatile chromium moly bar for oilfield, automotive, and tooling use.
High-tensile strength bar used in shafts, gears, and spindles.
What are the advantages of using alloy steel round bars in heavy-duty applications?
Alloy steel round bars are engineered for high strength, fatigue resistance, and durability under heat and pressure. With alloying elements like chromium, molybdenum, and nickel, these bars exhibit enhanced hardenability, wear resistance, and tensile strength. Their performance under extreme temperatures makes them ideal for power generation, heavy machinery, automotive transmission, and oilfield drilling components.
Which grades of Alloy Steel Round Bars are most commonly used, and what are their applications?
Common grades include EN19 (also known as 4140), EN24 (4340), and A182 F11/F22. EN19 is popular for shafts, bolts, and gears due to its excellent tensile strength and machinability. EN24 offers higher toughness and is used for aircraft components and heavy-duty gears. A182 grades are used for flanges and fittings in high-temperature service. These grades are selected based on the specific strength, heat resistance, and wear properties required by industries like oil & gas, tool-making, and heavy fabrication.
What is the material grade of round bar?
Round bars are available in various material grades depending on their intended application and required properties. Common materials include carbon steel, stainless steel, and alloy steel. Examples include ASTM A36, 1045, 304, 316, and 4140.
