Q420 ipuleti lensimbi

I-Q420 Steel Isingeniso
I-Q420 steel izinga lensimbi lesiShayina le-Low Alloy High Strength Structural Steel, Amandla Okukhiqiza angu-420 MPa, amapharamitha ahlolwa ngamabha ensimbi angu-16mm ububanzi noma amapuleti ensimbi, futhi amandla aqinile ngu-520-680 Mpa, ukuminyana kwezinto kungu-7.85 g/ /cm3. Ngokuya nge-GB/T 1591-2008, i-Q420 inamazinga ekhwalithi angu-5: Q420A, Q420B, Q420C, Q420D ne-Q420E. Ngokulingana kwensimbi ye-Q420, ukwakheka kwamakhemikhali kanye nezakhiwo zemishini, sicela ubheke amathebula angezansi kokuqukethwe.
Izici kanye nokusetshenziswa
Insimbi ye-Q420 inamandla amakhulu, ikakhulukazi esimweni esijwayelekile noma esijwayelekile kanye nesithambile, esinezakhiwo ezibanzi zemishini, ingasetshenziswa emikhunjini emikhulu, amabhuloho, imishini yesiteshi samandla kagesi, ama-boilers aphakathi nendawo naphezulu, imikhumbi enengcindezi ephezulu, imishini yokuphakamisa, imishini yezimayini kanye ezinye izingxenye ezinkulu zesakhiwo ezishiselwe.
