| Forged Steel Ring Application | Gear/Transmission,Metallurgy Field,Oi1&Gas Field,Ship-buil ding,Wind Energy,Chemi stry/PRV&Pipe,Mining,Sugar Plant Machinery,Construction,Power Generation/Motors and Others |
18CrMo4 (1.7243) alloy structure steel has good process performance and welding performance, and has a high persistence at 500 ~ 550 ° C. When the temperature exceeds 550 ° C, the antioxidant performance deteriorates, and the peristaltic strength is significantly reduced. When it is 500 ~ 550 ° C for a long time, the thermal strength of 18CrMo4 steel is reduced and the strength is reduced. 18CrMo4 is used to create a high, high-pressure steam catheter, set and tube wall temperature of 550 ° C at 510 ° C
