Kam uglerodli, molibden o'z ichiga olgan ostenitik zanglamaydigan po'latdan qotishma ASTM A182 F316L hisoblanadi. Yuqori korroziyaga chidamliligi tufayli u korroziy muhitda yoki suyuqliklarda kimyoviy ishlov berish, dengizda neft va gazni qidirish va dengiz ilovalarida qo'llanilishi mumkin. F316L past uglerodli tarkibga ega, bu uning payvandlanishini yaxshilaydi va donalararo korroziya va sezuvchanlik xavfini kamaytiradi. ASME B16.47 standarti gardishning o'lchami, bosim va harorat ko'rsatkichlari, yuz turlari, materiallari, bardoshliklari va gardishning yuqori sifati va foydaliligini kafolatlaydigan boshqa omillarga oid xususiyatlarni taqdim etadi.
ASTM A182 F316L spetsifikatsiyalari bo'yicha tayyorlangan payvandlangan bo'yin troyniklari qattiq va oqishsiz ulanishni taklif qilish uchun mo'ljallangan. Diqqatga sazovor xususiyatlarga mos keladigan qistirmalarni joylashtirishga yordam beradigan ko'tarilgan sirtlar, oqimning silliq o'tishlari uchun konusli uyalar va tez va aniq payvandlash uchun payvand choklari kiradi. Uzun bo'yinning mustahkamlanishi va stress kontsentratsiyasining kamayishi tufayli gardish yuqori bosim va yuqori haroratli ilovalar uchun javob beradi.
