I-ASTM A709 Ibanga le-HPS 50W ipuleti lensimbi

I-ASTM A709 Itholakala kumabanga ajwayelekile: 36, 50 kanye no-50W. Itholakala kumabanga asebenza kahle kakhulu: i-HPS 50W ne-HPS 70W. Izitifiketi ze-Dual ASTM kanye ne-AASHTO ziyatholakala. Amakhasimende angacacisa amamaki angu-A709 ukuze ahlangabezane nemfuneko yokuhlolwa kwe-Charpy yezindawo ezithile nesimo sezulu.

Ulwazi lomkhiqizo

I-ASTM A 709/A 709M A709 Ibanga le-HPS 50W iwuhlobo lwepuleti lensimbi lesimo sezulu eline-Cr,Ni,Mo ialloy lapho liginqika. I-low alloy steel plate A709 GR HPS 50W izoba ne-atmospheric corrosion resistance index of 6.0 noma ngaphezulu ebalwa kusukela ekuhlaziyeni ukushisa ngendlela yensimbi engu-G 101-predictive method esekelwe osukwini lwe-larabee ne-Coburn.Uma ivezwe kahle emkhathini. ,lawa mashidi ensimbi yesimo sezulu A709 Grade HPS 50W angasetshenziswa angenalutho futhi angapendiwe.

Izidingo Zobuchwepheshe Nezinsizakalo Ezengeziwe:

Ukuhlolwa kwengcindezi ephezulu
Ukuhlolwa okunomthelela kwezinga lokushisa eliphansi
Ukwelashwa kokushisa kwangemuva kwe-welded (PWHT)
Isitifiketi sokuhlola se-Orginal Mill esikhishwe ngaphansi kwe-EN 10204 FORMAT 3.1/3.2
Lapho i-cooper steel icaciswa ku-A709 Gr36, okuqukethwe ngu-Cu≥0.20%
Ukudubula nokupenda, Ukusika kanye nokushisela njengezidingo zomsebenzisi ngamunye

Ukwakheka kwamakhemikhali kanye nempahla yemishini

Impahla engumshini ye-A709 Grade HPS 50W low alloy steel:

Amandla esivuno (≥Mpa)	Amandla okuqina (≥Mpa)	Ukwelula ku-≥,%
345	485	200mm	50mm
		18	21

Ukwakheka kwamakhemikhali kwe-A709GrHPS 50W insimbi ye-alloy ephansi (Ukuhlaziywa Kokushisa Okuphezulu%)

Ukwakhiwa kwezakhi zamakhemikhali eziyinhloko ze-A709GrHPS 50W
C	Si	UMn	P	S	Ni	Cr	Cu	V	Mo	Al	N
0.11	0.30-0.50	1.10-1.35	0.02	0.006	0.25-0.40	0.45-0.70	0.25-0.40	0.04-0.08	0.02-0.08	0.01-0.04	0.015

Uhlolojikelele:

Ibanga elivamile lepuleti lensimbi elisetshenziswa ngokuyinhloko ekwenzeni amabhuloho.
Ugqinsi olusindayo (amayintshi angu-3 noma ugqinsi) olutholakala ezikhungweni eziningi zokusabalalisa ze-Leeco Steel.
Itholakala kumabanga ajwayelekile: 36, 50 kanye no-50W.
Itholakala kumabanga asebenza kahle kakhulu: i-HPS 50W ne-HPS 70W.
Amakhasimende angacacisa amamaki angu-A709 ukuze ahlangabezane nemfuneko yokuhlolwa kwe-Charpy yezindawo ezithile nesimo sezulu.
