韩国采购需求：中国钢丸，喷丸钢丸

I'm looking to procure steel shot within the size range of 1mm to 2mm. It's crucial that the gravity specification matches around 5, as this is key for our intended application. We need a reliable supplier who can provide a consistent quality of this material for our production processes. Additionally, please include information regarding your pricing, minimum order quantities, and lead times for delivery. If you have different grades or variations of steel shot available within the specified size and gravity, I'd appreciate any details on those options as well. Looking forward to your prompt response.
