印度尼西亚采购需求：锻造环、锻造轴、锻造盘、锻造块

I am reaching out to inquire about the availability and pricing of 2-meter stainless martensitic rings for our upcoming project. We are particularly interested in understanding the specifications, material grades, and any available customization options that you might offer. Our intention is to find high-quality rings that meet our rigorous standards for durability and performance. Additionally, it would be great to know about your lead times for production and delivery as well as any minimum order quantities. If you could also provide information regarding your payment terms and whether there are any ongoing promotions, that would be appreciated. Looking forward to your prompt response so we can move forward efficiently!
