Description
ASTM A285 Steel Plate
ASTM A285 is a standard specification from ASTM International (formerly known as the American Society for Testing and Materials) that covers pressure vessel platesmade of carbon steel. Its low to intermediate tensile strength makes it ideal for non-critical pressure vessel applications.
Key Features:
- Excellent weldability and formability
- Suitable for fabrication of pressure vessels and tanks
- Cost-effective for non-critical applications
- Available in as-rolled condition
