The Feasibility Study of 3Cr23Ni8Mn3N Used for High Power Diesel Engine Exhaust Valve Material
For the two kind of materials,3Cr23Ni8Mn3N and usually used 4Cr14Ni14W2Mo,the contrast and analysis of their mechanical property and microsructure show that 3Cr23Ni8Mn3N has superiority in structure,perfacrmance,heat treatment process,low cost with a wide solid dissolving treatment temperatures and fine grains.So 3Cr23Ni8Mn3N can satisfy the performance requirements for the high power diesel engine exhaust valve and have the feasibility of wide applications for this kind of parts.
