土耳其采购需求：因科乃尔合金、哈氏合金、Inconel 718、Invar 36、Haynes 188、蒙乃尔合金

We are currently in need of expansion joints and looking to order a total of 500 pieces across two different items. It's essential for us to secure these products promptly, as they are critical to our operations. If fulfilling the order for the expansion joints is not feasible, we would like to explore the option of acquiring the raw material, specifically Inconel X-750, instead. Please provide us with your availability, pricing, and lead times for both the expansion joints and the raw materials. We would appreciate a quick response, as we aim to finalize our procurement decisions shortly. Thank you for your assistance!
