ASTM A513 Grade 1010 Mechanical Steel Tubing

ASTM A513 is a standard that outlines the manufacturing and performance criteria for electric resistance-welded carbon and alloy steel tubing utilized in mechanical applications. This standard encompasses various shapes, grades, sizes, and properties of mechanical tubing, playing a pivotal role in guaranteeing the excellence, uniformity, and dependability of such tubing.

Dimensions of ASTM A513 Grade 1010 Mechanical Steel Tubing

• Standard: ASTM A513/ASME SA513
• Grade: 1010
• Outside Diameter: 6.35mm-305mm
• Wall Thickness: 0.56mm-3.4mm
• Tube Form: Round, square, rectangular, etc.

Electric resistance welding involves placing the metal components to be welded between two electrodes. By applying a specific force through these electrodes to bring the plates into close contact, an electric current is then passed through the plates from one electrode to the other. This welding technique utilizes the resistance heat generated by the current flowing through the contact surface and surrounding regions of the joint. Notably, this method doesnt necessitate the use of additional welding materials. tubes produced through this welding process exhibit high productivity, minimal deformation in the welded sections, and are conducive to automation.

Electric Resistance Welding Process

Grade 1010, in adherence to ASTM A513 standards, belongs to the category of mild steel. The designation "1010" reflects the nominal composition of the steel. In this nomenclature, the initial digit 1 signifies that carbon is the primary alloying element in the steel. The succeeding digit 0 indicates the absence of significant alloying elements other than carbon. The final two digits represent the average carbon content of 1010 carbon steel, which is 0.10%.

The chemical composition of ASTM A513 Grade 1010 mechanical steel tubing is rigorously regulated to meet the necessary chemical specifications. The precise chemical composition is outlined as follows:

• C 0.08-0.13
• Mn 0.30-0.60
• P, max 0.035
• S, max 0.035

The minimal carbon content plays a key role in fostering exceptional weldability and formability of the steel, while the presence of manganese serves to bolster its strength and hardenability. The restricted levels of phosphorus and sulfur contribute to good machinability and enhance the overall quality of the end product.

In addition to its chemical composition, the mechanical properties of ASTM A513 Grade 1010 demonstrate its suitability for mechanical applications. Typical mechanical properties include:

• Tensile Strength: 45,000 psi [310 MPa], min
• Yield Strength: 39,000 psi [270 MPa], min
• Elongation in 2 inches: 20%, min

These figures characterize a material possessing moderate strength, underscoring its capacity to endure mechanical stress effectively. The notable elongation signifies the materials capability to undergo deformation before reaching a point of rupture, a quality particularly advantageous in procedures like bending and forming.

Manufacturing Process of ASTM A513 Grade 1010 Mechanical Steel Tubing

The production journey of ASTM A513 Grade 1010, from the raw materials to the final product, entails a meticulously planned series of manufacturing processes. At its core lies the widely utilized electric-resistance-welding (ERW) method, known for its precision and efficiency in crafting steel tubing.

Initiating the manufacturing process, a flat steel strip, known as a skelp, is unwound from coils. This skelp undergoes a transformative journey through a sequence of forming rolls, shaping it into the desired configuration—typically round, square, or rectangular. The edges of the steel strip are then heated and fused together using the electric-resistance welding technique, resulting in a seamless joint. Subsequently, sizing rolls come into play to ensure the tubing achieves the specified dimensions and wall thickness.

The concluding phases involve cutting the tubing to the required lengths and, if deemed necessary, subjecting it to additional processes such as heat treatment or surface finishing. This holistic manufacturing process is designed to guarantee that ASTM A513 Grade 1010 adheres to the stringent requirements outlined in the standard.
