ASTM A358 quvurlari turli xalqaro standartlarga, jumladan ASTM, DIN, JIS, GB, AISI va boshqalarga muvofiq ishlab chiqariladi. ASTM A358 1-sinf quvurlari elektr termoyadroviy payvandlash (EFW) jarayoni yordamida ishlab chiqariladi.
ASTM A358 TP304 ning moddiy tarkibi taxminan 18% xrom, 8% nikel, marganets, kremniy, oltingugurt va fosforni o'z ichiga oladi. Taqqoslash uchun, ASTM A358 316L molibden qo‘shilishi tufayli yuqori korroziyaga chidamliligini ta’minlaydi, bu uning xlorid ionlari hujumiga qarshi turish qobiliyatini oshiradi. TP304 muvozanatli quvvati va iqtisodiy samaradorligi tufayli eng ko'p qo'llaniladigan nav bo'lib qolsa-da, 316L tajovuzkor muhitda afzallik beriladi.
Ushbu zanglamaydigan po'lat quvurlar diametri 8 dyuymdan 72 dyuymgacha, devor qalinligi 3 mm dan 60 mm gacha bo'lgan keng o'lchamlarda mavjud. UNS S31254 kabi sinflarda ko'rinib turganidek, standart uzunliklar 6 metrgacha cho'zilishi mumkin.
ASTM A358 TP304L EFW quvurlari turli xil ilovalar ehtiyojlarini qondirish uchun turli xil sirt qoplamalari bilan ta'minlanishi mumkin, jumladan tuzlangan, yorqin tavlangan (BA), No. 4 cho'tkasi va elektropolizlangan. Bundan tashqari, bir xil sinfda 1 va 2-sinf o'rtasida farqlar mavjud: 1-sinf ko'proq qo'llanilsa-da, 2-sinf yaxshilangan mexanik xususiyatlarni taqdim etadi, bu esa uni yuqori ishlashni talab qiluvchi maxsus ilovalar uchun mos qiladi.
