Cad é ábhar A672 C65?
A672 GrC65 CL22 belongs to the carbon-manganese-silicon steel series. Its chemical composition is meticulously designed, with carbon content controlled below 0.22%, manganese content between 1.0-1.5%, and appropriate silicon added to enhance strength and toughness. This alloy formulation enables the steel pipe to maintain good plasticity while possessing high yield strength (>415MPa) agus neart teanntachta (Níos mó ná nó cothrom le 485MPa).
Is díol suntais go háirithe, tar éis dul faoi phróisis rollta agus fuaraithe rialaithe speisialta, go n-éiríonn leis an ábhar éifeachtaí scagtha gráin suntasacha agus cruas tionchair íseal teochta den scoth, a chomhlíonann riachtanais seirbhíse go hiomlán ag -46 céim . Maidir le friotaíocht creimeadh, trí eilimintí micrea-chóimhiotail a chur leis agus rialú docht ar ábhar sulfair agus fosfair, comhlíonann a fhriotaíocht HIC (Scáineadh Ionduchtaithe Hidrigin) agus SSC (Creimeadh Creimthe Strus Sulfíd) caighdeáin NACE MR0175, rud a fhágann go bhfuil sé oiriúnach go háirithe do choinníollacha oibriúcháin crua ina bhfuil suilfíd hidrigine.
