ASTM A709 ibyuma

Icyuma gikomeye-cyoroshye, icyuma-cyubatswe cyubatswe icyuma gikoreshwa cyane cyane mugukora ibiraro. Gnee ibyuma bibitse A709 Icyiciro cya 36, ​​A709 Icyiciro cya 50 na A709 Icyiciro cya 50W. Aya manota akunze kugaragara hamwe na Charpy ibizamini byerekana zone yihariye cyangwa ubushyuhe bwa serivisi buteganijwe. Ibizamini bya Charpy bisobanurwa nkibidacika intege, ni ikizamini kuri buri bushyuhe (inshuro "H"), cyangwa kuvunika cyane, ni ikizamini kuri buri sahani (Frequency "P").

Ibisobanuro:
Umubyimba: 3mm - 150mm
Ubugari: 30mm - 4000mm
Uburebure: 1000mm - 12000mm
Bisanzwe: ASTM EN10025 JIS GB
