Yeyiphi into esetyenziswa yiP235GH? Yeyiphi into esetyenziswa yiTshayina?

I-P235GH ngumbhobho wentsimbi ye-Fihekin kunye ne-alloy esebenza ngobushushu obuphezulu, oyintsimbi yesakhiwo yaseJamani enobushushu obuphezulu. Umbhobho wentsimbi engenamthungo we-P235GH, EN10216-2 ohambelana nomgangatho wesizwe we-20G, 20MnG (GB 5310-2008 wombhobho wentsimbi engenamthungo).

Umbhobho wentsimbi ye-alloy ye-P235GH umbhobho ongenamthungo uhlala unyibilikiswa kwisithando sombane se-arc kunye nesiguquli se-oxygen esiphezulu. Ngenxa yeemfuno eziphezulu, isebenzisa ukucocwa ngaphandle kwesithando somlilo, ukunyibilikiswa kwesithando somlilo se-vacuum induction okanye ukunyibilikiswa kwesithando somlilo kabini, ukunyibilikiswa kwe-electroslag okanye unyango lwe-vacuum, kunye nonyango lobushushu.

Umbhobho wentsimbi engenamthungo ye-P235GH, EN10216-2 ufanelekile ukuvelisa izitya zoxinzelelo kunye nezixhobo. Xa kuthelekiswa nentsimbi eqhelekileyo, intsimbi ye-alloy ye-P235GH inamandla aphezulu kunye nokuqina, ukusebenza kokugoba okubandayo kunye nokusebenza kokuwelda, iipropati zeekhemikhali, ukuhambelana kwezinto eziphilayo, iipropati zomzimba kunye nokusebenza kwenkqubo.

Iipropati zoomatshini zombhobho wentsimbi ye-alloy ye-P235GH: amandla okutsalwa σb350~480 MPa; amandla okukhupha σs≥215 MPa; ubude δ5≥ 25%; amandla okufunxa impembelelo Akv≥47 J; Ubulukhuni beBrinell ≤105~140 HB100

Ulwakhiwo lweekhemikhali (iqhezu lobunzima, %) lombhobho wentsimbi ye-alloy ye-P235GH: ≤0.16 Si; 0.60~1.20 Mn; ≤0.025 Cr; ≤0.30 Ni; ≤0.30 Cu; ≤0.08 Mo; ≤0.02 V; ≤0.02 Nb; ≤0.012 N; P; ≤0.010 S; ≤0.30, ≤0.020 Al; C; ≤0.35, ≤0.03 Ti.
