Yintoni imathiriyeli ye-P235GH? Yeyiphi imathiriyeli ehambelana nayo eTshayina?

I-P235GH yi-high-temperature performance Fihekin kunye ne-alloy steel pipe, eyintsimbi yesakhiwo saseJamani esinobushushu obuphezulu. I-P235GH, i-EN10216-2 yoxinzelelo lombhobho wentsimbi engenamthungo ihambelana nomgangatho wesizwe we-20G, 20MnG (GB 5310-2008 ibhoyili ephezulu yoxinzelelo lombhobho wentsimbi ongenamthungo).

Umbhobho wentsimbi ye-alloy we-P235GH ongenamthungo uhlala unyibilikiswa kwiziko lombane le-arc kunye nesiguquli esivuthelwa phezulu ngeoksijini. Ngeemfuno eziphezulu, ithatha ukucocwa ngaphandle kwesithando somlilo, ukunyibilika kwesithando somlilo okanye ukunyibilika kwe-vacuum kabini, ukunyibilika kwe-electroslag okanye unyango lwe-vacuum, kunye nonyango lobushushu.

I-P235GH, EN10216-2 umbhobho wensimbi ongenamthungo ulungele ukwenza iinqanawa zoxinzelelo kunye namacandelo ezixhobo. Xa kuthelekiswa nentsimbi eqhelekileyo, intsimbi ye-P235GH ye-alloy inamandla aphezulu kunye nokuqina, ukugoba okubandayo kunye nokusebenza kwe-welding, iipropathi zeekhemikhali, ukuhambelana kwezinto eziphilayo, iipropati zomzimba kunye nokusebenza kwenkqubo.

Iipropati ze-Mechanical ze-P235GH i-alloy steel pipe: amandla okuqina σb350 ~ 480 MPa; isivuno samandla σs≥215 MPa; ubude δ5≥ 25%; impembelelo yokufunxa amandla Akv≥47 J; Ukuqina kweBrinell ≤105~140 HB100

Ukubunjwa kweekhemikhali (iqhekeza elikhulu,%) ye-P235GH i-alloy steel pipe: ≤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.
