Steel sheet has three actual pairings of requested length with width ranges900–1500mm. Reference thickness2.0–3.5mm needs an exact selected value.

Resolve grade designations

Q345B/C/D/E andQ390/B/C are material references. Ambiguous Q345BC/BD/BE andQ420 title labels require actual clarification rather than silent correction.

• Flat-sheet shape.
• Non-alloy designation.
• ±1% tolerance reference.
• Multiple standard names.
• Ship/boiler application contexts.

Specify mechanical evidence

High-strength wording gives no measured yield, tensile or toughness result. Select actual material and test criteria.

Agree project acceptance

High-pressure-vessel context does not establish approved pressure material, design stress or structural capacity. Request actual composition, mechanical tests and blank dimensions for the intended project. Specify impact-test temperature and acceptance scope when toughness evidence is required.
