| Abstract Scope |
Alloy 12Cr is one of the iron-based high-alloys used for multiple industrial sectors with several derivatives. Alloys J152 and J160 were developed 25-year ago to meet ever-increased challenges in internal-combustion-engine industry to achieve higher power output, lower combustion emission, and product cost reduction. While J160 is a higher end of version to address the new challenge of wear and corrosion resistant, J152 has an advantage of lower cost.A comparative study using alloys J152 and J160 was carried out to define high-temperature capability for engine valvetrain applications. Basic alloy design applied along with microstructural characterization, property test, and hot hardness comparison was discussed. The project was also adopted to support effort of sustainable-materials-engineering involving high-alloy industry. |
