Frequently Asked Questions (FAQ)
-
Q: What is ST52-3 steel equivalent to in other standards?
A: ST52-3 is a German standard (DIN 17100) structural steel. It is roughly equivalent to ASTM A572 Grade 50 or EN 10025 S355JR, though exact mechanical properties may vary. Always check the specific requirements of your project. -
Q: Can this plate be welded without preheating?
A: Yes, ST52-3 has good weldability for most common welding processes (MIG, TIG, stick). For thicker sections (over 20mm) or high constraint joints, a preheat of 100-150°C may be recommended to avoid hydrogen cracking. Consult your welding engineer. -
Q: What is the standard tolerance for thickness?
A: According to DIN 17100, the thickness tolerance for a 20mm plate is typically ±0.5mm to ±1.0mm, depending on the width and rolling conditions. We provide mill certificates with actual measurements. -
Q: Do you offer cutting services for non-standard sizes?
A: Yes, we can cut the plates to custom dimensions using plasma or shearing. Please inquire about processing fees and lead times. -
Q: Is this plate suitable for outdoor structures exposed to weather?
A: ST52-3 is not a weathering steel; it will rust if unprotected. For outdoor use, we recommend applying a suitable paint or coating system. Alternatively, we can supply with a primer upon request. -
Q: How do you pack the plates for export?
A: Plates are packed in bundles with steel straps, protected with waterproof paper and plastic film, or wooden crates for smaller quantities. The packaging meets international shipping standards. -
Q: What is the minimum order quantity?
A: For standard sizes (1500x3000x20mm), our MOQ is 10 tons. For custom sizes, please contact our sales team to discuss feasibility. -
Q: Can you provide a sample for testing?
A: Yes, sample plates (e.g., 300x300mm) can be provided at a nominal cost. Please reach out to arrange a sample request.
