摘要： PURPOSE:To inexpesively manufacture a high strength bolt having high thermal expansibility by incorporating specified amounts of C, Si, Mn, Ni and V. CONSTITUTION:The compsn. of the objective steel 15 formed of, by weight, >0.65 to 1.15% C, 0.5 to 3% V and satisfying Ni+0.5XMn+30XC--5.3X>=21, and the balance substantial Fe. C is an element for forming austenite, furthermore forms vanadium carbide with V and brings about an age hardening effect. For this purpose, its addition by is needed >0.65% at the lowest. In the case its content exceeds 1.15%, its ductility is reduced, and the header workability of a bolt is deteriorated. Mn stabilizes the austenitic phase and imparts high thermal expansibility thereto. At the time of subjecting the bolt to cold header working, it is excellent in formability because of its low proof stress and high ductility, and by the subsequent aging treatment, sufficient high proof stress can be obtd.
