Isishwankathelo

Yonke into esiyenzayo idla ngokunxulunyaniswa netenet yethu " Umthengi kuqala, Thembela kuqala, uzinikele ekupakishweni kokutya kunye nokhuseleko lokusingqongileyo kuMgangatho oPhezulu ongenamthungo kunye nombhobho wentsimbi odityanisiweyo, Sibeka ukunyaniseka kunye nempilo njengoxanduva oluphambili. Ngoku sinengcali yobungcali. Iqela lezorhwebo lamazwe ngamazwe eliphumelele eMelika sibe liqabane lakho leshishini elilandelayo Ukubambelela kumgaqo othi "Ukufuna Inyaniso, Ukuchaneka kunye noManyano", kunye neteknoloji njengengundoqo, inkampani yethu iyaqhubeka nokwenza izinto ezintsha, ezizinikeleyo ekuboneleleni. ngezona mveliso zinexabiso eliphezulu kunye nenkonzo ecokisekileyo emva kokuthengisa.

Phakathi kwezinto eziqhelekileyo zemibhobho yensimbi engenamthungo, i-DIN1629 ST52 yenye yezona zinto zisetyenziswa ngokuqhelekileyo. Kwimigangatho yaseTshayina, ngokuqhelekileyo ihambelana ne-GB/T8162 Q345B. Ezi zimbini zinokuthathelwa indawo enye kwenye, kodwa azihambelani ngokupheleleyo. .

Ngokokwakheka kweekhemikhali:

I-DIN 1629 ST52: C: 0.17% max; P: 0.04% max; S:: 0.04% max; N: 0.009% max

GB/T 8162 Q345B: C: 0.2% max; P: 0.035% max; S:: 0.035% max; N: 0.012% max

Kuyabonakala ukuba le migangatho mibini idibanisa ukuba umxholo wemichiza uyafana.

Ukusebenza koomatshini:

I-DIN 1629 ST52: Amandla okuqina: 500 ~ 650Mpa; Amandla esivuno: 335 ~ 355Mpa; Ubude (longitudinal): 21%min

I-GB/T 8162 Q345B: Amandla e-Tensile: 470 ~ 630Mpa; Amandla esivuno: 295 ~ 345Mpa; Ubude (longitudinal): 20% min

Iimfuno zeempawu zoomatshini zezi zimbini nazo ziphantse zifane

Izinto zovavanyo:

I-DIN 1629 idinga uvavanyo lokuxinana, uvavanyo oluthambileyo, uvavanyo lokuqina, ukuhlolwa komphezulu, ukuhlolwa komda; uhlalutyo lwemveliso egqityiweyo

I-GB/T8162 Q345B ifuna ukuhlolwa kokwakheka kweekhemikhali, uvavanyo lwe-tensile, uvavanyo lokuqina, uvavanyo lwempembelelo engama-20℃, uvavanyo olucwebezelayo, uvavanyo lokugoba, uvavanyo lombane olungonakalisi.

Inokubonwa ukuba iimfuno zeprojekthi yovavanyo ye-GB/T8162 Q345B ngokusisiseko igubungela i-DIN1629

Iimfuno zokunyamezela:

I-DIN1629 ithi:

OD ukunyamezela:

OD≤100mm, ±1% okanye±0.5mm
100mm＜OD≤200mm, ±1%
OD＞200mm, ±1%
Ukunyamezela kwe-WT:

OD≤130mm: ≤2* iWT eqhelekileyo: + 15% -10%
2*standard WT＜s≤4*standard WT:+12.5% -10%
＞4* iWT eqhelekileyo: ±9%
130mm＜OD≤320mm:≤0.05*WT eqhelekileyo:+17% -12.5%
0.05*i-WT eqhelekileyo＜s≤0.11*i-WT eqhelekileyo: ±12.5%
＞0.11* iWT eqhelekileyo: ±10%
320mm＜OD≤660mm:≤0.05*WT eqhelekileyo: +20% -15%
0.05 * i-WT eqhelekileyo＜s≤0.09* i-WT eqhelekileyo: + 15% -12.5%
＞0.09* iWT eqhelekileyo: +12.5% -10%

I-GB/T8162 imisela:

OD ukunyamezela:

±1% okanye ±0.5mm enkulu
Unyamezelo lwe-WT:

OD≤102mm: ± 12.5% okanye ± 0.4mm enkulu
OD＞102mm:WT≤0.05mm, ±15% okanye ±0.4mm enkulu
0.05mm＜WT≤0.1mm, ±12.5% okanye ±0.4mm enkulu
WT-0.1mm, +12.5% -10%

Ukunyamezela kwezi zibini kukwafana ngokufanayo

Ngoko ke, i-Q345B kunye ne-ST52 inokutshintshwa omnye komnye xa isetyenziswe kwindawo eqhelekileyo kwaye akukho mfuneko ekhethekileyo. Xa okusingqongileyo okanye iimfuno zingqongqo, uthelekiso kufuneka luqwalaselwe ngononophelo.
