Icwecwe leNsimbi le-ASTM SA283GrC/Z25 linikezelwe kwimeko eHot eqengqelekayo ye-SA283GrC imo yokuhanjiswa:
Imo yokuhanjiswa kwe-SA283GrC: Ngokubanzi kwimeko yokuhanjiswa eshushu, imeko yonikezelo ethile kufuneka iboniswe kwiwaranti.
Ixabiso loluhlu lwemichiza ye-SA283GrC: Qaphela: Eyona mveliso yekhemikhali kwiwaranti yefektri yentsimbi iya kuphumelela.
ICarbon C: ≤0.24 Si: (ipleyiti yentsimbi ≤40) ≤0.40 (ipleyiti yentsimbi> 40) 0.15-0.40
IManganese uMn: ≤0.90 iSulfur S: ≤0.040 Phosphorus P: ≤0.035
Copper Cu: 0.20 okanye ngaphantsi
I-SA283GrC ipleyiti yentsimbi ifanelekile kwi-riveting, bolting kunye nezakhiwo ze-welding kwiiBridges kunye nezakhiwo.Yinjongo eqhelekileyo ye-carbon structural steel kunye ne-structural steel quality.
I-SA283GrC imeko yokuhanjiswa kwepleyiti yentsimbi: ukuqengqeleka okushushu, ukuqengqeleka okulawulwayo, imeko eqhelekileyo yokuhanjiswa
Isixhobo sokwakha isithando somlilo SM400ZL ipleyiti yentsimbi:
I-SM400ZL yipleyiti yentsimbi ekumgangatho ophantsi waseJapan esezantsi-amandla aphezulu kwiqokobhe lomguquli.Lo mgangatho uchaza ubungakanani, imilo, iimfuno zobugcisa, iindlela zovavanyo, imithetho yokuhlola, ukupakishwa, amanqaku kunye nezatifikethi zomgangatho weepleyiti zentsimbi zesithando somlilo, isiguquli kunye namaqokobhe omlilo oqhumayo.Isebenza kwipleyiti yentsimbi yeqokobhe leziko elinobukhulu be-8mm ~ 200mm.Ukuphambuka kobunzima obungalunganga be-SM400ZL ipleyiti yensimbi ikhawulelwe kwi-0.25mm, kwaye indawo yokunyamezela ukutyeba iya kuhambelana ne-GB/T709.
Ipleyiti yentsimbi ye-S355NL [8-200 eshinyeneyo] yokusika ukwakheka, uluhlu lwezinto eziphathekayo:
Umgangatho wesigqeba se-S355NL: EN10025-3: igama elipheleleyo: ukuqheleka/ukulungelelanisa ipleyiti yentsimbi eqengqelekayo eqengqelekayo.Lo mgangatho kunye ne-EN 10025-1 kunye kunye endaweni ye-EN 10113-1: 1993 imveliso yentsimbi ethambileyo eqengqelekayo eqengqelekayo eqengqelekayo edityanisiweyo, icandelo 1: Imiqathango ngokubanzi kunye ne-EN 10113-2:1993 iimveliso zentsimbi yolwakhiwo olushushu oluqengqelekayo oluqengqelekayo oluqengqelekayo, Icandelo II: ukuqheleka/ukuqheleka iimeko zentsimbi eziqengqelekayo.Xa ubushushu bebakala bungekho ngaphantsi kwe-20 ° C, ixabiso elincinci lamandla empembelelo echaziweyo libonakaliswe kwi-N;xa iqondo lobushushu lingekho ngaphantsi kwe-50 ° C, ixabiso elincinci lamandla empembelelo echaziweyo libonakaliswe kwi-NL.
2. Intsingiselo ehambelanayo ye-S355NL ye-steel plate grade letter:
S: intsimbi yolwakhiwo, N: iphondo, ikomkhulu L: inqanaba lefuthe elisezantsi elikhankanyiweyo xa ubushushu bungekho ngaphantsi kwe-50 ° C.
S355ML ipleyiti yentsimbi [8-200mm ubukhulu] thermomechanical rolling
Ipleyiti yentsimbi ye-S355ML ihanjiswa kwimeko yokuqengqeleka komatshini we-thermo
I-S355ML yeeMfuno zokuBunjwa kweMichiza
C: ≤0.14,Si:≤0.5,Mn:≤1.6，P:≤0.025，S:≤0.02,Nb:≤0.05,V:≤0.1,Al:≤0.02,Ti:≤0.05,Cr:3,≤0,Cr:. NONE
Ipleyiti yentsimbi ye-S355ML yintsimbi yolwakhiwo lwenkozo ecikizekileyo eqengqelekayo eqengqelekayo, eyeyoluhlu lweepleyiti zentsimbi ezinomgangatho ophantsi wealloyi.Yimveliso ejikeleziweyo ecaba kunye nobukhulu obungekho ngaphezu kwe-120mm kunye nemveliso ende kunye nobukhulu obungekho ngaphezu kwe-150mm.I-S ithetha insimbi yesakhiwo, i-355 ibonisa ukuba ixabiso elincinci lesivuno sobunzima obuchaphazelekayo obungaphantsi kwe-16mm yi-355MPa, kwaye i-M imele ukuhanjiswa kwayo, oko kukuthi, ukutshisa okutshisa.Umgaqo kukuba impembelelo kwiqondo lokushisa elingekho ngaphantsi kwe-50 degrees iboniswa ngonobumba omkhulu u-L. S355 i-non alloy structural steel.
Umda wokusetyenziswa kwepleyiti yensimbi ye-S355ML
Ukongeza kwi-EN10,025-1 yensimbi, iplani yensimbi echazwe ngokukodwa kulo mgangatho iphinda isetyenziswe kwiindawo ezithwala imithwalo yezakhiwo ezidibeneyo ezisetyenziselwa ukujikeleza amabhuloho, i-sluices, iitanki zokugcina, iitanki zokuhambisa amanzi, njl kunye nokushisa okuphantsi.
