FAQ

Round Bar Chrome Plated Rod AISI 4140 Steel Annealed Forging Hot Rolled Steel

Our company is a premier supplier of high-quality round bars and chrome plated rods made from AISI 4140 steel. We offer these products in various forms, including annealed, forged, and hot rolled, catering to the demanding requirements of multiple industrial applications.

AISI 4140 Steel Overview

AISI 4140 steel is a chromium-molybdenum alloy steel known for its excellent mechanical properties, including high tensile strength, toughness, and wear resistance. Its balanced composition makes it an ideal choice for components subjected to high stress and demanding conditions.

Product Forms and Processing

Round Bar

Our AISI 4140 round bars are manufactured to stringent standards, ensuring consistent quality and performance. These bars are available in various diameters and lengths, making them suitable for a wide range of applications.

• Properties: High tensile strength, good ductility, and excellent wear resistance.
• Applications: Commonly used in the production of shafts, gears, bolts, and other critical machine components.

Chrome Plated Rod

The AISI 4140 chrome plated rods are designed to provide superior surface hardness and corrosion resistance. The hard chrome plating process involves electroplating a thin layer of chromium onto the steel rod, enhancing its surface properties.

• Benefits: Improved wear and corrosion resistance, reduced friction, and enhanced lifespan.
• Applications: Ideal for hydraulic cylinders, piston rods, and various industrial machinery parts.

Annealed AISI 4140 Steel

Annealing AISI 4140 steel involves heating the steel to a specific temperature and then slowly cooling it. This process softens the steel, improving its machinability and ductility while maintaining adequate strength.

• Characteristics: Enhanced machinability, increased ductility, and reduced hardness.
• Uses: Suitable for applications requiring extensive machining or forming, such as tool and die making.

Forging

Forged AISI 4140 steel provides exceptional strength and toughness, making it ideal for heavy-duty applications. The forging process aligns the grain structure of the steel, resulting in superior mechanical properties.

• Advantages: Enhanced strength, improved impact resistance, and excellent fatigue properties.
• Applications: Commonly used in the production of crankshafts, connecting rods, and high-stress components in heavy machinery.

Hot Rolled Steel

Hot rolling AISI 4140 steel involves rolling the steel at high temperatures, which improves its formability and surface finish. This process is used to produce large quantities of steel bars with consistent dimensions and properties.

• Key Features: Improved surface finish, consistent mechanical properties, and good formability.
• Typical Uses: Suitable for construction, automotive, and general engineering applications.

Quality Assurance

We adhere to strict quality control measures to ensure that our AISI 4140 steel products meet the highest standards of performance and reliability. Each product undergoes rigorous testing to verify its mechanical properties, dimensional accuracy, and surface quality.

• Testing Methods: Our quality assurance process includes hardness testing, tensile testing, impact testing, and non-destructive testing methods.
• Certifications: We provide material test certificates (MTC) and other relevant documentation to verify the quality and traceability of our products.
