I-Q245b iyinsimbi evamile yesakhiwo sekhabhoni enamandla okukhiqiza angama-245 MPa, okuyingxenye yensimbi ebulewe kancane.
Okuqukethwe kwekhabhoni cishe ku-0.05% kuya ku-0.70%, kanti okunye kungaba phezulu ku-0.90%.Ingahlukaniswa ngezinhlobo ezimbili: insimbi evamile ye-carbon structural kanye nekhwalithi ephezulu ye-carbon structural steel.Kukhona ukusetshenziswa okuningi kanye nenani elikhulu lokusetshenziswa.Isetshenziswa kakhulu kojantshi wesitimela, amabhuloho, kanye namaphrojekthi wokwakha ahlukahlukene ukwenza izingxenye zensimbi ezahlukahlukene ezithwala imithwalo engashintshi, kanye nezingxenye ezingabalulekile zemishini ezingadingi ukwelashwa kokushisa kanye nokushiselwa okujwayelekile.
Ibanga:Q195, Q215 ,Q235, Q345,A36,SS400,10#,45#,ST35,ST52,16MN Okujwayelekile: AISI ASTM JIS SUS DIN EN kanye ne-GB Usayizi: Ngokwezicelo zekhasimende Isu: Okubandayo Kugoqe futhi Kushiswe Izitifiketi: ISO 9001,SGS,BV
Ngemuva kokwelashwa kokushisa, izakhiwo zemishini zomkhiqizo ziphelele kakhulu, futhi amandla okucindezela angafinyelela ku-1100-1300mpa (160-190ksi).Leli banga alikwazi ukusetshenziswa emazingeni okushisa angaphezu kuka-300 ℃ (570f) noma amazinga okushisa aphansi kakhulu.Inokumelana nokugqwala okuhle emkhathini kanye ne-asidi ehlanjululwe noma usawoti.Ukumelana nokugqwala kwayo kuyafana nokuka-304 no-430.
