その一方が焼付き防止性能を向上させる特定の鋼製である対の誘導要素
Document Type and Number:
Japanese Patent JP5363805
Kind Code:
B2
Abstract:
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.
