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.
