Quality Assurance
Testing: Includes mechanical tests (tensile, impact), non-destructive tests (ultrasonic, radiographic), and chemical composition analysis.
Certification: Often required from recognized bodies to ensure compliance with standards and specifications.
Considerations
Thickness: Must be chosen based on the pressure and temperature requirements of the application.
Welding: The steel must be weldable; different grades have varying weldability.
Impact Toughness: Critical for low-temperature applications to prevent brittle failure.
