泰国采购需求：不锈钢棒，不锈钢圆棒

I'm looking for specific rail specifications for a project. The primary requirements include centerless grinding bars with a surface finish of 16RA. The diameter should be 9mm with a tolerance of +0-0.04mm. Additionally, I require chromium plating as a surface treatment, with a chrome thickness of 10-20 microns on each side. In terms of material, I need standard steel conforming to European specifications, specifically C45. Please let me know if you can supply this type of rail and any relevant details regarding lead times, pricing, and availability. Looking forward to your prompt response!
