德国采购需求：锻造、自由模锻、自由模锻、钢锻、热锻、重型锻造

I'm looking to purchase a forging roll for a hot forging application and need your expertise on what steel grade would be best suited for high-temperature and high-stress conditions. Additionally, could you provide the chemical composition and the heat treatment details for the recommended material? I also need information on your estimated delivery timeline from order confirmation to arrival at our location, including the shipping method you'll be using. Lastly, please let me know if quality certificates such as chemical analysis, hardness, and microstructure are available. I appreciate your attention to these details and look forward to your response.
