Umehluko phakathi kwe-Q460NC steel plate kanye ne-Q460C, ukusebenza kwe-Q460NC steel plate kungaphezu kuka-80
Umehluko phakathi kwepuleti lensimbi le-Q460NC ne-Q460C ukuthi ukujiya kwepuleti lensimbi le-Q460NC kungaphezu kuka-80, futhi ipuleti lensimbi elijwayelekile i-Q460NC iyinsimbi enealloy ephezulu enamandla.I-Q ebangeni le-Q460NC imele amandla okukhiqiza ensimbi.Osonhlamvukazi;460 imele 460 MPa, mega 10 amandla 6th, futhi Pa iyunithi ingcindezi Pascal;I-Q460 isho ukuthi ukuguqulwa kwepulasitiki kuzokwenzeka kuphela lapho amandla omshini wensimbi efinyelela ku-460 MPa, okungukuthi, lapho kukhululwa amandla angaphandle, Insimbi ingakwazi ukugcina isimo samandla kuphela futhi ayikwazi ukubuyela esimweni sayo sokuqala, esinamandla kakhulu insimbi evamile.U-N umele ukugoqa okujwayelekile noma okujwayelekile, i-C—izinga lekhwalithi ngu-C (amabanga ahlukaniswe ngo-C, D, E).
Isimo sokudiliva se-Q460NC steel plate: normalizing, normalizing rolling
Ukwakheka kwamakhemikhali kweshidi lensimbi le-Q460NC Ukwakheka kwamakhemikhali kwensimbi egoqiwe evamile futhi evamile: C: ≤ 0.20, Si: ≤ 0.60, Mn: 1.00-1.70, P: ≤ 0.030, S: ≤ 0.030, Nb: 0.001-0: 0.01-0. -0.20, Ti: 0.006-0.05, Cr: ≤ 0.30, Ni: ≤ 0.80, Cu: ≤ 0.40, Mo: ≤ 0.10, N: ≤ 0.015, Als: ≥ 0.015.
