自体の耐焼付性の向上効果によるものである。The presence of carbides which particularly improves the wear resistance by additions such as (2) and the addition of Co are due to the effect of improving the seizure resistance of the base itself due to the Co dissolved in the base.
第３表 第４表に本願発明材料の抗折試験による靭性値を示す。Table 3 Table 4 shows the toughness values of the materials of the present invention as determined by bending tests.
本願発明鋼は比較鋼Ｒよりも炭化物量は多いが靭性はす

に分布しており、巨大炭化物や偏析が存在しないことに
よるもので、比較鋼よりも耐摩耗性、靭性ともにすぐれ
、有利な特性、を保持していることがわかる。The invention steel has a larger amount of carbides than Comparative Steel R, but has superior toughness. This is because the carbides of the invention material are fine and uniformly distributed, and there are no macrocarbides or segregation, and the material has superior wear resistance and toughness compared to comparative steels. I understand that.

The test piece was 101 mφ, and when the end face was repeatedly pressed against the epoxy resin in a plastic state, the limit number of times that the resin would not stick when it was pulled up was compared with the cases of comparative steel and Cr plating, and the end face was repeatedly pressed against the epoxy resin in a plastic state. The limit number of times is compared with that of comparative steel and Cr plating, and is expressed as an index with that of comparative @H set as 100. The material of the present invention exhibits resin adhesion resistance that is clearly superior to comparative steel,
It shows mold release characteristics comparable to Cr plating.

。The grindability is calculated by calculating the wear volume of the grindstone/volume removed by grinding, and is expressed as an index with that of comparative steel R set as 100. Although the material of the present invention has relatively lower grindability than Comparative Steel R, it does not decrease significantly and is within a sufficiently practical range.
