Frequently Asked Questions

Q: What is the difference between VIM and VAR smelting processes?
A: VIM (Vacuum Induction Melting) is used for initial melting to ensure high purity, while VAR (Vacuum Arc Remelting) further refines the material by removing impurities and improving homogeneity, resulting in superior mechanical properties.
Q: Can you provide material test reports for this product?
A: Yes, we provide EN 10204 3.1 material test certificates with every shipment, detailing chemical composition, mechanical properties, and other relevant test results.
Q: What is the typical lead time for custom sizes?
A: For custom sizes, the lead time is typically 14-21 working days, depending on the specific requirements and our production schedule. We'll provide an accurate estimate after receiving your inquiry.
Q: Is this material suitable for welding applications?
A: Yes, 17-4PH stainless steel has good weldability in the solution treated condition. However, post-weld heat treatment may be required to achieve optimal mechanical properties.
