4 로 계산되는 J 파라미터와, 볼트 직경을 사용하여, 한랭지에서의 사용 가부를 판별한다.
The created bolt using a chromium molybdenum steel, inspection of the wind bolts without conducting Charpy impact test for performing a troublesome operation, and a bolt that can be used for cold, can be classified as not available for the cold vault to provide the method, the created bolt by using the heat treatment is a chrome-molybdenum steel embodiment, in the inspection method of the bolt to determine use permitted in the cold region, phosphorus (P), silicon described in the chromium molybdenum steel steel inspection certificate (Si), manganese (Mn), tin (Sn) P% of each of the content (mass%), Si%, Mn%, by using Sn% J = (Si% + Mn%) × (P% + Sn%) and using the parameters J, bolt diameter that is calculated to × 10
4, and determines whether or use in cold district.
