I-Q245b yintsimbi eqhelekileyo ye-carbon structural ene-245 MPa enamandla, eyeyentsimbi e-semi-killed.
Umxholo wekhabhoni umalunga ne-0.05% ukuya kwi-0.70%, kwaye ezinye zingaba phezulu njenge-0.90%.Inokwahlulwa ibe ziindidi ezimbini: intsimbi eqhelekileyo ye-carbon structural kunye ne-high-quality carbon structural steel.Kukho iindlela ezininzi zokusetyenziswa kunye nomthamo omkhulu wokusetyenziswa.Isetyenziswa ikakhulu koololiwe, iibhulorho, kunye neeprojekthi ezahlukeneyo zokwakha ukuvelisa amacandelo esinyithi ahlukeneyo athwala imithwalo engatshintshiyo, kunye neenxalenye zoomatshini ezingabalulekanga ezingadingi kunyango lobushushu kunye nokuwelda ngokubanzi.
IBakala:Q195, Q215 ,Q235, Q345,A36,SS400,10#,45#,ST35,ST52,16MN Umgangatho: AISI ASTM JIS SUS DIN EN kunye ne-GB Ubungakanani: Ngokwezicelo zomthengi Ubuchwephesha: Okubandayo Kuqengqelekisiwe kwaye Kushushu Kuqengqiwe Iziqinisekiso: ISO 9001,SGS,BV
Emva kokunyanga ubushushu, iimpawu zomatshini wemveliso zigqibelele ngakumbi, kwaye amandla oxinzelelo anokufikelela kwi-1100-1300mpa (160-190ksi).Eli bakala alinakusetyenziswa kumaqondo obushushu angaphezu kwama-300 ℃ (570f) okanye amaqondo aphantsi kakhulu.Inokumelana ne-corrosion efanelekileyo kwi-atmosfera kunye ne-asidi edibeneyo okanye ityuwa.Ukumelana nokubola kwayo kuyafana naleyo ye-304 kunye ne-430.
