Frequently Asked Questions (FAQ)
-
Q: What is the typical tolerance for the diameter of these round bars?
A: Our hot-rolled round bars are manufactured to standard tolerances per AISI specifications. For diameters 12mm-250mm, typical tolerance is ±0.5mm to ±1.5mm depending on size. Please contact us for specific tolerance requirements. -
Q: Can you provide custom lengths for forging applications?
A: Yes, we offer customizable lengths up to 12 meters. Shorter lengths or specific cut lengths are available upon request to reduce waste and improve your process efficiency. -
Q: Are these bars suitable for induction hardening after forging?
A: AISI 1045 steel responds well to induction hardening, making it a popular choice for parts requiring surface hardness like gears and shafts. We recommend conducting a trial with your specific process parameters. -
Q: What packaging options do you offer for export?
A: We provide standard sea-worthy packaging including bundles with steel straps, waterproof wrapping, and wooden crates for smaller diameters. Custom packaging is also available. -
Q: How do you ensure the quality of sawn ends?
A: Each bar is cut using precision sawing equipment, and the ends are inspected for squareness and burrs. We can also provide chamfered ends upon request to facilitate handling. -
Q: What is the minimum order quantity (MOQ) for these round bars?
A: Our MOQ is typically 1 ton per diameter, but we can accommodate smaller trial orders for new customers. Please inquire for specific details. -
Q: Do you have a certificate of material test report (MTR) for each batch?
A: Yes, we provide a mill test certificate (MTC) compliant with ISO 9001 requirements for each shipment, ensuring traceability and chemical/mechanical properties. -
Q: Can you supply bars with a black surface or pickled finish?
A: The standard finish is hot-rolled black surface. Pickled and oiled finish is available as an option for applications requiring a cleaner surface. Please specify your preference.
