Din 17175 ko'tarilgan harorat uchun changsiz po'lat quvurlar
Nov 04, 2025
Ushbu standart changdan yasalgan po'lat naychalarga, shu jumladan isitmadan qilingan - 1-jadvalda keltirilgan, sarlavhalar uchun ishlatiladigan 1-jadvalda keltirilgan tikuv po'latlarga qo'llaniladi. Ushbu naychalar bug 'qozonlari, quvurlar, bosimli kemalar, bosimli tomirlar va haroratda ishlaydigan asbobsozlik uchun 600 daraja. Umumiy yuk va o'ziga xos oksizing sharoitlarining o'zgarishi tufayli belgilangan harorat chegaralari mos ravishda kamayishi yoki ko'payishi mumkin.
