Alloy Steel Round Bars: Versatile and High-Performance Solutions

Alloy steel round bars are crafted from various material grades like A-182, F5, F9, F11, F12, F22, and F91. These materials are composed of corrosion-resistant and robust metal alloys, each with unique compositions and specifications that adhere to specific standards. Whether you're looking for durability or resistance against harsh conditions, these bars cater to a wide range of industrial needs.

One notable example is the SAE 4140 rod, which features a blend of carbon, silicon, nickel, phosphorus, manganese, chromium, and sulfur. This combination ensures excellent strength and resilience. The alloy steel round bars are renowned for their exceptional properties, including high tensile strength, which typically ranges between 850MPa and 1000MPa, making them ideal for demanding applications. Additionally, they possess superior wear resistance, ensuring longevity even under challenging conditions.

These alloy steel round bars offer several key advantages:

  • High mechanical strength
  • Excellent corrosion resistance
  • Superior dimensional stability
  • Longer operational lifespan
  • Resistance to extreme temperatures

In terms of specifications, alloy steel round bars conform to standards such as ASTM A182 and ASME SA182. Their dimensions can vary widely, with diameters ranging from 5mm to 500mm and lengths from 100mm to 6000mm. Common diameters include options from 10mm to 200mm, while thicknesses can extend up to 500mm. Available grades include High Speed Steel (HSS) varieties like M2, M3, M35, M42, T-1, T-4, T-15, T-42, D2, D3, H11, H13, OHNS-01, and EN52. Surface finishes may include black finish, bright polishing, rough turning, No.4 finish, matte finish, or BA finish. Lengths typically range from 1000mm to 6000mm, and forms include round, square, hexagonal (A/F), rectangular, billet, ingot, and forged options.

Applications span across industries, including welding companies, oil and gas sectors, chemical plants, laboratories, and more. They are particularly suited for high-temperature and cryogenic environments, making them indispensable in diverse fields.
