Product Q&A
Q:Can you provide the Mill Test Certificate (MTC)?
A:
Yes, we provide EN 10204 3.1 MTC with every shipment, detailing chemical composition and mechanical properties. Third-party inspection (SGS/BV) is also welcome.
Q:What is the difference between Hot Rolled and Forged bars?
A:
Hot rolled bars are generally for smaller diameters (usually <100mm). Forged bars are for larger diameters (>100mm) and offer better internal density and mechanical properties for critical parts.
Q:Do you offer heat treatment services?
A:
Yes, we can provide Quenching and Tempering (Q+T), Annealing, or Normalizing services according to your required hardness (e.g., HB 250-300).
Q:Can I visit your factory before placing an order?
A:
Absolutely! We encourage factory visits. It is the best way to verify our quality and capacity. We have a dedicated team to handle visa invitation letters, airport pick-up, and accommodation arrangements. Whether you are checking the raw materials or inspecting the finished 40CrNiMoA bars, we will accompany you throughout the process.
Q:Do you provide samples for testing?
A:
Yes. For standard sizes, we can provide free samples (freight collect). For customized specifications or large forged bars, we can produce a sample batch for your approval before mass production.
