ASTM A709 steel hlau

Lub zog muaj zog, qis-alloy steel phaj siv feem ntau hauv kev tsim cov choj. Gnee steel stocks A709 Qib 36, A709 Qib 50 thiab A709 Qib 50W. Cov qhab nia no feem ntau teev nrog Charpy cov kev xeem xa mus rau thaj chaw tshwj xeeb lossis qhov ntsuas kub qis tshaj qhov kev pabcuam. Cov kev ntsuam xyuas Charpy tau teev tseg tias tsis muaj kev puas tsuaj tseem ceeb, uas yog ib qho kev ntsuas kub ib zaug (frequency "H"), lossis kev puas tsuaj tseem ceeb, uas yog ib qho kev sim ib phaj (Frequency "P").

Cov specifications:
Thickness: 3mm-150mm
Dav: 30mm-4000mm
Ntev: 1000mm-12000mm
Txuj: ASTM EN10025 JIS GB
