Insimbi ye-ASTM A709

Ipuleti lensimbi elinamandla amakhulu, elinengxubevange ephansi elisetshenziswa ngokuyinhloko ekwenzeni amabhuloho. I-Gnee steel stocks A709 Grade 36, A709 Grade 50 and A709 Grade 50W. Lawa mabanga avame ukucaciswa ngokuhlolwa kwe-Charpy okubhekisela endaweni ethile noma izinga lokushisa eliphansi elilindelwe lesevisi. Ukuhlola kwe-Charpy kucaciswa njengokubalulekile okunganqamuki, okuwukuhlolwa kokushisa ngakunye (imvamisa ethi "H"), noma ubucayi bokuphuka, okuwukuhlola kwepuleti ngalinye (Imvamisa "P").

Imininingwane:
Ubukhulu: 3mm-150mm
Ububanzi: 30mm-4000mm
Ubude: 1000mm--12000mm
Okujwayelekile: ASTM EN10025 JIS GB
