Chemical composition of 13MnNiMo54, simulated post-welding properties of 13MnNiMo54

Thread Content

13MnNiMo5-4 is mainly used for manufacturing the drum of steam drums in power plant boilers with capacities of 100,000 to 300,000 watts and above. In the 1980s, Wugang took on a key national research project to achieve domestic production of 145mm-thick BHW35 (13MnNiMo5-4) boiler drum plates. The 13MnNiMo5-4 series of plates specifically designed for boiler drum use come in thicknesses such as 65mm, 95mm, 135mm, 145mm, etc. The chemical composition of 13MnNiMo54 steel plates shall meet the requirements in Table 1, and the control of trace elements shall be carried out in accordance with GB713-1997.

No cracks allowed. For values >125, ≤145: 375. Note 1: The impact values listed in the table are the averages of 3 specimens. It is acceptable for one impact value to be lower than the specified value, but it must not be lower than 27 J.

The simulated post-weld heat treatment process involves heating to 600±10°C and holding at that temperature for 7 hours, after which the temperature is reduced to 400°C at a rate of less than 100°C/hour, followed by cooling in air outside the furnace. Applications of 613mnnimo54: Thanks to the uniqueness of its applications and its advanced product technology, 13mnnimo54 is already being exported in large quantities to other regions, including Southeast Asia, the Middle East, and Africa. At the end of 2010, Wugang Yicheng Trading Co., Ltd. entered into a cooperation agreement with Wuyang Iron and Steel Co., Ltd. for the exclusive distribution of hydrogen-resistant chromium-molybdenum steel.
