Pressure vessel and boiler projects depend on traceable material. When you inquire, mention the design code your engineer works to (ASME, GB, EN) and the grade on the drawing—such as SA516 Grade 70 or equivalent domestic grades.
Documents
Standard quotations should clarify:
- Mill test certificate (MTC) with heat number
- Chemical and mechanical results matching the ordered grade
- Ultrasonic test level if your spec requires it
We coordinate with mills that can issue proper certificates for export. Include required thickness and impact test temperature if your spec is low-temperature service.
