Iyiphi impahla engu-P235GH? Ihambisana yiphi impahla e-China?

I-P235GH ukusebenza kwezinga lokushisa eliphezulu I-Fihekin kanye nepayipi lensimbi ye-alloy, okuyinsimbi yesakhiwo yaseJalimane enezinga eliphezulu lokushisa. I-P235GH, EN10216-2 ingcindezi yepayipi lensimbi engenamthungo ihambisana nezinga kazwelonke 20G, 20MnG (GB 5310-2008 high-pressure boiler steel pipeless steel).

Ipayipi lensimbi eliyingxubevange le-P235GH elingenamthungo livamise ukuncibilikiswa esithandweni se-arc sikagesi nesiguquli esiphephezelwa phezulu komoyampilo. Ngezidingo eziphezulu, yamukela ukucwengwa ngaphandle kwesithando somlilo, ukuncibilikisa kwesithando sokungenisa ivacuum noma ukuncibilika kwe-vacuum okuphindwe kabili, ukuncibilika kabusha kwe-electroslag noma ukwelashwa kwe-vacuum, nokwelashwa kokushisa.

I-P235GH, EN10216-2 ipayipi lensimbi engenamthungo ilungele ukukhiqiza imikhumbi yengcindezi nezingxenye zemishini. Uma kuqhathaniswa nensimbi evamile, insimbi ye-P235GH alloy inamandla aphezulu kanye nokuqina, ukusebenza okubandayo okugoba nokusebenza kokushisela, izakhiwo zamakhemikhali, ukuhambisana kwezinto eziphilayo, izakhiwo zomzimba kanye nokusebenza kwenqubo.

Izakhiwo zemishini yepayipi yensimbi ye-P235GH alloy: amandla aqinile σb350 ~ 480 MPa; isivuno amandla σs≥215 MPa; ubude δ5≥ 25%; umthelela ukumuncwa amandla Akv≥47 J; Ubulukhuni beBrinell ≤105~140 HB100

Ukwakheka kwamakhemikhali (ingxenyana yobuningi, %) yepayipi yensimbi ye-P235GH ingxubevange: ≤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.
