Frequently Asked Questions

Q: What is the typical tensile strength of your stainless steel 304 spring wire?
A: Typical tensile strength ranges from 700 MPa to 1200 MPa, depending on the diameter and temper. We can adjust the tensile strength within this range to match your spring design. Please specify your requirement when ordering.
Q: Can you supply wire with a diameter smaller than 0.3mm or larger than 3mm?
A: Our standard range is 0.3mm to 3mm. For diameters outside this range, please contact us to discuss feasibility. We can produce custom sizes based on minimum order quantities.
Q: What packaging options are available?
A: We offer wire in coils, spools, or wound on carriers. Coil weight can be from 5 kg to 50 kg. We can also provide wooden spools, steel spools, or custom packaging for export. Please advise your preferred method.
Q: Is the wire suitable for automatic spring coiling machines?
A: Yes, our cold-drawn spring wire is designed to run smoothly on automatic spring coiling machines. The consistent diameter and surface finish reduce machine downtime and improve product quality.
Q: Do you provide samples for testing?
A: Yes, we can provide free samples within a reasonable length. You only need to cover the shipping cost. Contact us with your specifications to request a sample.
Q: What is your lead time for bulk orders?
A: Typical lead time is 15-30 days after order confirmation, depending on the quantity and specification. For urgent orders, we can expedite production upon request.
