Pair of guiding elements of which one is made of specific steel leading to improved anti-seizing performances
摘要：
A pair of guiding elements is characterized in that at least one of its elements is made of a steel containing at least 0.15 to 0.3% by weight of carbon, 2 to 5% (preferably 2 to 3%) by weight of chromium, at least 0.45% (preferably no greater than 0.9%) by weight of molybdenum, and at least 0.01% by weight and no greater than 0.5% (preferably no greater than 0.3%) of vanadium. This steel is nitrided after being shaped whereby obtaining a compound layer consisting of iron and nitrogen atoms of a thickness ranging from 5 to 50 micrometers. The steel can also contain 0.4% to 1.5% by weight of manganese.
摘要（中）：

一对引导元件的特征在于，其元件中的至少一个由至少含有0.15至0.3重量％的碳，2至5重量％（优选2至3重量％）的铬，至少包含 0.45重量％（优选不大于0.9重量％）的钼，至少0.01重量％且不大于0.5重量％（优选不大于0.3重量％）的钒。 该钢在成型后氮化，由此获得由铁和氮原子组成的化合物层，其厚度为5至50微米。 钢还可以含有0.4重量％至1.5重量％的锰。
