Yiluphi uhlobo lwe-P235GH? Luhlobo luni lwe-P235GH oluhambisana nalo eShayina?

I-P235GH iyipayipi lensimbi ye-Fihekin ne-alloy esebenza kahle kakhulu ekushiseni okuphezulu, okuyinsimbi yesakhiwo yaseJalimane eshisa kakhulu. Ipayipi lensimbi engenamthungo ye-P235GH, EN10216-2 lihambisana nepayipi lensimbi elingenamthungo le-20G, 20MnG (GB 5310-2008 elisezingeni likazwelonke).

Ipayipi lensimbi ye-alloy ye-P235GH ipayipi elingenamthungo ngokuvamile lincibilikiswa ku-electric arc furnace kanye ne-oxygen top-blown converter. Ngenxa yezidingo eziphezulu, isebenzisa ukucwengisisa ngaphandle kwesithando, ukuncibilikisa isithando sokungenisa i-vacuum noma ukuncibilikisa i-vacuum kabili, ukuncibilikisa i-electroslag noma ukwelashwa nge-vacuum, kanye nokwelashwa ngokushisa.

Ipayipi lensimbi engenamthungo ye-P235GH, EN10216-2 lifanelekela ukukhiqiza imikhumbi yokucindezela kanye nezingxenye zemishini. Uma kuqhathaniswa nensimbi evamile, insimbi ye-alloy ye-P235GH inamandla aphezulu kanye nokuqina, ukusebenza kokugoba okubandayo kanye nokusebenza kokushisela, izakhiwo zamakhemikhali, ukuhambisana kwezinto eziphilayo, izakhiwo zomzimba kanye nokusebenza kwenqubo.

Izakhiwo zemishini zepayipi lensimbi ye-alloy ye-P235GH: amandla okudonsa σb350~480 MPa; amandla okukhiqiza σs≥215 MPa; ukunwebeka δ5≥ 25%; amandla okumunca umthelela Akv≥47 J; Ubulukhuni beBrinell ≤105~140 HB100

Ukwakheka kwamakhemikhali (ingxenye yesisindo, %) yepayipi lensimbi 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.
