Description
Jiangsu Liangyi professional manufacturer of 23H12MNF open die forging parts and seamless rolled rings factory from china
23H12MNF is a tempered stainless, high-temperature chromium steel with molybdenum addition, which is used as a standard steel for components in steam turbines and high-temperature bolts. The vanadium addition increases the creep and creep rupture strength. Scale resistance up to approx. 600°C is given.
Its application owes to its high resistance to fatigue stress. 23H12MNF also features elements and parts of aircraft construction,
components in the chemical, petrochemical and petrochemical industries, as well as parts used in the power industry.
