Precision Custom Steel Fabrication: Seamless Supply Chain · Rapid Delivery
9Cr / L80-9Cr / UNS S50400 / 9Cr1Mo alloy is widely used in key equipment in the energy, petrochemical and power industries, such as hydrogenation reactors, cracking units, high-temperature and high-pressure pipelines in oil refining, and boiler superheaters, reheaters and steam pipeline systems in thermal power plants.
In addition, L80-9Cr, as one of the standard steel grades of API-5CT, is widely used in oil casing, tubing, string connection components, etc.
In terms of manufacturing process, 9Cr / L80-9Cr / UNS S50400 / 9Cr1Mo is often optimized through heat treatment (such as normalizing + tempering) and processed into complex components by welding or forging.
