ASTM SA283GrC/Z25 Steel Sheet inounzwa muchimiro chekupisa chakamoneredzwa SA283GrC Mamiriro ekutumira:
SA283GrC mamiriro ekutumira: Kazhinji kana zvinhu zvanyatsogadzirwa panguva yekutumira, mamiriro chaiwo ekutumira anofanira kuratidzwa muwarandi.
SA283GrC makemikari akagadzirwa nemakemikari: Cherechedza: Makemikoro chaiwo ari muwarandi yefekitori yesimbi ndiwo achashandiswa.
Kabhoni C: ≤0.24 Si: (ndiro yesimbi ≤40) ≤0.40 (ndiro yesimbi > 40) 0.15-0.40

Copper Cu: 0.20 kana pasi
Plate yesimbi yeSA283GrC yakakodzera kuturikira, kuputira nekusonerera zvivakwa zvemabhiriji nezvivakwa. Isimbi yakagadzirwa nekabhoni ine mhando yesimbi yakagadzirwa.
SA283GrC mamiriro ekutumira ndiro yesimbi: kupisa kutenderedza, kutenderedza kunodzorwa, mamiriro akajairika ekutumira
Zvinhu zvekuvaka chitofu chekupisa cheSM400ZL:
SM400ZL iplate yesimbi yakasimba ine simba shoma yekuJapan inoshandiswa pakugadzira shell ye converter. Iyi standard inotsanangura saizi, chimiro, zvinodiwa zvehunyanzvi, nzira dzekuyedza, mitemo yekuongorora, kurongedza, mamaki uye zvitupa zvemhando yepamusoro zveplate dzesimbi dze blast furnace, converter uye hot blast furnace shells. Inoshanda kune plate yesimbi ye blast furnace shell ine ukobvu hwe 8mm ~ 200mm. Kutsauka kweukobvu hwe SM400ZL steel plate kwakaganhurirwa ku -0.25mm, uye nzvimbo yekushivirira ukobvu inofanira kutevedzera GB/T709.
S355NL simbi plate [8-200 gobvu] musanganiswa wekucheka, runyorwa rwezvinhu:
S355NL executive standard: EN10025-3: zita rakazara: normalizing/normalizing rolled weldable fine grain structural steel plate. Iyi standard ne EN10025-1 pamwe chete zvinotsiva EN 10113-1:1993 hot-rolled weldable fine grain structural steel products Chikamu I: General conditions uye EN 10113-2:1993 hot-rolled weldable fine grain structural steel products Chikamu II: normalizing/normalizing rolled steel conditions. Kana tembiricha yegiredhi isiri pasi pe -20 ° C, kukosha kushoma kwesimba reimpact rakatarwa kunoratidzwa muNL; kana tembiricha isiri pasi pe -50 ° C, kukosha kushoma kwesimba reimpact rakatarwa kunoratidzwa muNL.
2. Zvinorehwa netsamba yesimbi yeS355NL inoenderana:
S: simbi yekuvaka, N: mamiriro, guta guru L: mwero wesimba reimpact shoma rakatarwa kana tembiricha isiri pasi pe - 50 ° C
Ndiro yesimbi yeS355ML [8-200mm ukobvu] inotenderedzwa nethermomechanical
Simbi yesimbi yeS355ML inounzwa iri mumamiriro ekutenderera kwemechanical
Zvinodiwa paKuumbwa kweMakemikoro eS355ML
C：≤0.14,Si：≤0.5,Mn：≤1.6，P：≤0.025，S：≤0.02,Nb：≤0.05,V:≤0.1,A 1
Ndiro yesimbi yeS355ML isimbi inogadziriswa nekupisa inokweshwa, inosanganiswa nemaplate esimbi ane simba rakaderera. Ichi chigadzirwa chakapetwa chakati sandara chine ukobvu husingapfuure 120mm uye chigadzirwa chakareba chine ukobvu husingapfuure 150mm. S zvinoreva simbi inogadziriswa, 355 inoratidza kuti kukosha kudiki kweukobvu hwakakodzera husingasviki 16mm i355MPa, uye M inomiririra kuburitswa kwayo, kureva, kutenderedza kunopisa. Mutemo ndewekuti kukanganiswa pakupisa kweasingasviki - 50 degrees kunoratidzwa nebhii guru L. S355 isimbi inogadziriswa isina alloy.
Kushandiswa kwesimbi yesimbi yeS355ML
Pamusoro pesimbi yeEN10,025-1, hurongwa hwesimbi hwakatsanangurwa zvakanyanya muchiyero ichi hunoshandiswawo kune zvikamu zvinotakura mutoro zvezvivakwa zvakasungirirwa zvinoshandiswa zvakatenderedza mabhiriji, nzvimbo dzinoyerera mvura, matangi ekuchengetera, matangi emvura, nezvimwewo uye nekupisa kwakaderera.
