J55 API korpusi yoki quvurlari neft burg'ilashda nisbatan keng tarqalgan. J55 ning past po'lat darajasi tufayli,
u sayoz neft va gaz qazib olish uchun ishlatiladi. Boshqa po'lat navlari orasida past narxi tufayli u kengroq zavqlanadi
ilovalar. J55 API korpusi yoki quvurlari tabiiy gaz va ko'mir metanini qazib olishda keng qo'llaniladi,
va odatda sayoz quduqlarda, geotermal quduqlarda va suv quduqlarida topilishi mumkin.
