ASTM A682
Basic Info
ASTM A682 STEEL is a standard specification for cold-rolled steel strip. In terms of carbon content, it typically contains low to medium levels of carbon, depending on the grade specified within the standard. The mechanical performance of ASTM A682 STEEL can vary based on factors such as the grade, processing, and heat treatment. Generally, it offers good formability, strength, and surface finish suitable for a wide range of applications including automotive, appliances, and electronics.
Characteristics
Good Formability: It can be easily formed into various shapes without sacrificing its structural integrity, making it suitable for complex manufacturing processes.
High Strength: Despite its formability, ASTM A682 steel maintains excellent strength properties, ensuring structural integrity and durability in applications subject to mechanical stress.
Excellent Surface Finish: The cold-rolled process results in a smooth and uniform surface finish, ideal for applications where aesthetics are important, such as automotive panels and appliances.

Fabrication and Welding
Formability
- Fabrication Considerations: ASTM A682 steel exhibits excellent formability, making it suitable for various cold forming processes such as bending, stamping, and drawing.
- Welding Considerations: Weldability of ASTM A682 steel is generally good, but proper preheating and control of interpass temperatures may be necessary for thick sections to prevent cracking.
Machinability
- Fabrication Considerations: ASTM A682 steel typically has good machinability characteristics, allowing for ease of machining operations such as drilling, milling, and turning.
- Welding Considerations: ASTM A682 steel can be welded using commonly used welding methods such as shielded metal arc welding (SMAW), gas metal arc welding (GMAW), and gas tungsten arc welding (GTAW). Preheating and post-weld heat treatment may be required for thick sections to minimize the risk of weld cracking.
Heat Treatment
- Fabrication Considerations: Heat treatment processes such as annealing or stress relieving may be required for certain applications to improve the material’s properties or relieve internal stresses.
- Welding Considerations: Proper edge preparation is essential for quality welds, and the weld area should be clean and free of contaminants to ensure sound welds.
Surface Finish
- Fabrication Considerations: ASTM A682 steel typically has a smooth surface finish after cold rolling, which may require additional surface treatment such as pickling or coating for specific applications.
- Welding Considerations: Welded joints should be carefully inspected for defects such as porosity, cracking, or incomplete fusion, and appropriate non-destructive testing methods may be employed to ensure weld quality.
Edge Condition
- Fabrication Considerations: ASTM A682 steel is available with either mill edge or slit edge conditions, and proper edge preparation is crucial for subsequent fabrication processes such as welding or forming.
- Welding Considerations: Welding parameters, including welding currents, voltages, travel speeds, and electrode or filler metal selections, should be carefully controlled to achieve desired weld properties and minimize the risk of defects.
