Titre
(EN) Improved bearing steel
(ZH) 改进型轴承钢
Abrégé
(EN) The present invention relates to a bearing steel comprising at least 0.6 percent by weight of carbon, 0.007 percent by weight or less of phosphorous, and optionally other alloying element(s); the balance being iron, or iron and impurities. The present invention also relates to a bearing consisting of the bearing steel.
(ZH) 本发明涉及一种轴承钢,其包括至少0.6重量%的碳、0.007重量%或者更少的磷和任选其它合金元素(一种或多种),余量为铁或铁和杂质。本发明也涉及以一种由该轴承钢构成的轴承。
