A practical evidence checklist for RFQ preparation and supplier evaluation.
CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
According to GB/T 709, the typical thickness range is 6 to 120 mm. However, the exact thickness available depends on the supplier and the specific grade. Always confirm the required thickness with the manufacturer or supplier.
Per GB/T 1591, the yield strength is typically 235–345 MPa, tensile strength 370–630 MPa, and elongation 20–30%. Carbon content ranges from 0.12% to 0.20%. These are reference values; actual properties vary by grade and heat treatment.
Yes, it is commonly used for pressure vessels and storage tanks. For pressure vessel grades, ultrasonic testing per GB/T 2970 is required. However, compliance with specific standards must be verified with the supplier, as certification is not implied.
The maximum service temperature is typically 400 °C, above which creep becomes significant. For lower temperatures, the minimum service temperature is -20 °C for standard grades, but lower temperatures may be available for special grades. Confirm with the supplier.
