Description
【０００６】
この様な事情に鑑みて、 Pyrowear675（商品名＝Ｃを０．０７重量％、Ｐを０．００５重量％以下、Ｓを０．００３重量％以下、Mnを０．６５重量％、Siを０．４０重量％、Crを１３．００重量％、Ｖを０．６０重量％、Moを１．８０重量％、Niを２．６０重量％、Coを５．４０重量％含有し、残りをFeと不可避不純物とした鉄系合金）の様な、耐熱・耐蝕鋼を使用する場合がある。但し、この様な耐熱・耐蝕鋼により、転がり軸受１ａ〜１ｃの内輪２ａ〜２ｃ及び外輪５ａ〜５ｃを造ると、表面を硬化させる為に浸炭処理を施すのに伴って、これら内輪２ａ〜２ｃ及び外輪５ａ〜５ｃの表面にCr炭化物が析出し、この表面の耐蝕性が低下する為、やはり十分な耐久性を確保する事が難しくなる。
