ASTM A709 intsimbi

Ipleyiti yentsimbi enomgangatho ophezulu, ephantsi-alloy esetyenziswa ikakhulu ekwenzeni iibhulorho. I-Gnee steel stocks A709 Grade 36, A709 Grade 50 and A709 Grade 50W. La mabanga ahlala ecaciswa ngovavanyo lwe-Charpy olubhekiselele kwindawo ethile okanye ubushushu benkonzo obulindelekileyo obusezantsi. Iimvavanyo ze-Charpy zichazwe njenge-non-fracture ebaluleke kakhulu, i-test-heat test (i-frequency "H"), okanye i-fracture ebalulekileyo, i-per-plate test (Frequency "P").

Iinkcukacha:
Ukutyeba: 3mm--150mm
Ububanzi: 30mm--4000mm
Ubude: 1000mm--12000mm
Umgangatho: ASTM EN10025 JIS GB
