Qurilish uchun ASTM A992 keng gardishli H nuri

ASTM A992 po'latdirHozirgi vaqtda butun dunyo bo'ylab keng gardishli nurlar uchun eng mavjud po'lat navi deb tan olingan. U vanadiy yoki kolumbiy, mis, nikel, xrom va molibden kabi bir nechta qotishma elementlarni o'z ichiga oladi, bularning barchasi uning kuchini va boshqa xususiyatlarini sezilarli darajada yaxshilaydi. Mexanik xususiyatlar, masalan, A572-50 va A36 - valentlik kuchi 65ksi va oqish kuchi 65ksi dan ancha yaxshi. Shunday qilib, A992 keng gardish nurlari (H nurlari) odatda A572-50 o'rnini egallaydi.

Mahsulot tavsifi:

Element: A992 Vt-nur (yoki H-nur).

Texnologiya: issiq haddelenmiş.

Yuzaki ishlov berish: qora, galvanizli yoki astarlangan.

O'lchamlari: HEA, HEB va HEM.

Eslatma: Nostandart H nurlarining o'lchamlari buyurtma asosida mavjud.
