Embodiment 1
[0014] Embodiment 1: adopt the material of following chemical composition content to make engine exhaust valve seat: (weight percentage)
[0015] C: 1.08%, Mo: 6.58%, Cr: 3.5%, Co: 5.51%, Ni: 2.28%, V: 0.72%, Cu0.56%, and the rest Fe.
[0016] The production process is:
[0017] Ingredients → forming → sintering → machining → external inspection → packaging.
[0018] 250 times the metallographic structure of the exhaust valve seat made by figure 1 shown.
Embodiment 2
[0019] Example 2: C: 1.12%, Mo: 6.6%, Cr: 3.55%, Co: 5.54%, Ni: 2.31%, V: 0.7%, Cu0.55%, and the rest Fe.
[0020] The manufacturing process is the same as example 1.
