AISI 1030 Carbon Steel Chemical Composition, Grade, Chart and Online Pdf

AISI 1030 carbon steel is a medium-to-high-carbon steel, having decent breaking strength and malleability. The chemical elements that comprise it, carbon 0.28% to 0.34%, manganese 0.60% to 0.90%, phosphorus 0.04%, and sulfur 0.05% respectively, are a primary part of it. This steel grade has excellent machining and welding attributes and, therefore, works well for use on hundreds of applications in machine parts, discards, shafts, gears, and automotive components. AISI 1030 is extensively used in rolling states, specified normalization or re-rolling state. Due to its middle strength and hardness, it delivers from forming to forging and to heat treatment operations easily. Engineers and manufacturers are highly dependent on its consistency. These characteristics can be extracted from tables, labeled charts through PDF documents available online for accurate material specifications and operational instructions.

AISI 1030 Carbon Steel Chemical Composition And Grade Table

АISI 1030 is medium alloy structural steel positioned in the middle of strength/ductility duet. It is characterized by carbon content ranging between 0.28 to 0.34 % and manganese 0.60 to 0.90%, as well as phosphorus with 0.040% and sulfur of 0.050%. Also, it may have other elements such as silicon, which implies low copper concentration. The combination of iron and carbon results in a steel grade which has easy machining, welding, and conversion to different parts like shafts, gears, and machinery parts. With its carbon content yet not too high, it can be hardened to improve mechanical properties of the material, thus finding its meaning in the fabrication of complicated engineering devices.

Advantages and Disadvantages of AISI 1030 Carbon Steel

    Advantages:

  • Heat Treatable: Can be heat treated to improve strength and hardness.

  • Good Machinability: Easier to machine by conventional techniques compared to other materials in this group.

  • Moderate Toughness: Combines strength and shear/tensile wall strength while providing impact protection.

  • Weldable: Possible with proper preheating methods and welding procedures.

    Disadvantages:

  • Corrosion Susceptibility: Needs protection against rusting to serve its intended use.

  • Limited Hardenability: Only hardens to a certain depth.

  • Wear Resistance: Easier to deform than higher carbon steels due to reduced wear resistance.

  • Distortion: May deform during heat treatment processes.
