Where in China can 15Mo3 and 16Mo materials be produced?

I recently encountered a 15Mo3 container as well; those who are familiar with this material could please provide some information

Henan Longpeng Marine Metal Materials Co., Ltd. mainly supplies thick and wide steel plates; it can provide steel plates that meet German and European standards, as well as steel plates for boilers and containers such as 19Mn6, 15Mo3, 16Mo3, etc. Certified under the EU PED standard, with EN10204 3.1 certification available – Henan Longpeng Marine Metal Materials Co., Ltd. supplies Wuyang steel plates!

Note: 1. When yield behavior is not distinct, the specified non-proportional strain strength Rp0.2 is used in place of the yield strength. 　　2. For seamless steel tubes made from St35.8, St45.8, 15Mo3, 13CrMo44, 10CrMo910, and 14MoV63 steels, those with an outer diameter of not more than 30 mm and a wall thickness of not more than 3 mm can have a minimum yield strength that is 10 MPa lower. 　　3. For steel pipes made of 15Mo3 and 13CrMo44 with a wall thickness of not more than 10 mm, the minimum yield strength must be 15 MPa higher.

15Mo3 is a grade specified in DIN17155; its chemical composition is as follows: C Si Mn P S Al Cr Mo – 0.12~0.2, 0.1~0.35, 0.4~1.6, ≤0.035, ≤0.0350, ≥0.02, 0.025, 0.25~0.35. Its mechanical properties are as follows (for specimens of 40 mm or less): yield strength of 270, tensile strength of 440~590, elongation of ≥20%, and impact strength at room temperature of ≥31 J. Our company can supply sheets with a thickness of over 8 mm, as well as forged steel ingots, forgings, and shaped steel products. Wuhan Iron and Steel Panglong MSN: gupan777@163.com

Reply to 2# realben: Wuyang Steel Plant can produce it; call me if you need it

As for 15Mo3 and 16Mo3 steel pipes, there are many steel mills that can produce them: A. Shanghai Baosteel Group Corporation; B. Jiangxi Hongdu Steel Mill; C. Tianjin Steel Pipe Group; D. Jiangsu Chengde Steel Pipe Co., Ltd
