FAQ
Q: Is 11SMnPb30 RoHS compliant for European customers?
A: No, it contains lead and is restricted under RoHS. If your product must be RoHS compliant, you should switch to lead-free 1215 or 1212. We stock 1215 and can supply it with a material certificate showing zero lead. (Substitution approval must be confirmed by your design engineer.)
Q: Does 11SMnPb30 machine the same as 12L14 on automatic screw machines?
A: Yes, they machine almost identically. Both are leaded free-cutting steels. The lead acts as a lubricant, breaking chips into small pieces. You can run 11SMnPb30 on a setup designed for 12L14 without changing feeds and speeds.
Q: What is the surface finish of your cold-drawn bars?
A: We supply bright, smooth cold-drawn bars with tight tolerances (h11 or better). The smooth surface from our in-house cold drawing process reduces wear on guide bushings and collets during high-speed machining.
Q: What lead-free grades do you recommend for the US market?
A: For the US market, we recommend 1215 or 1212. Leaded steels face increasing restrictions, so using lead-free grades clears customs and customer audits safely. We can supply 1215 directly from stock.
Q: Can you provide short hex bars to test machinability?
A: Yes, we can cut 1–2 meter lengths of hex bar for your trial. Machinability depends heavily on your tooling and speeds, so testing is always recommended before ordering a full production batch.
