arllwys: ①. Lleihau'r terfyn uchaf gan {{0}}.01 y cant carbon, gan ganiatáu 0.04 y cant manganîs ychwanegol. Ar gyfer ZG 200 ~ 400 manganîs hyd at 1.00 y cant, y pedwar gradd arall manganîs uchel i 1.20 y cant.
②. Ni fydd cyfanswm yr elfennau gweddilliol yn fwy nag 1.00 y cant . Os nad oes angen y prynwr, efallai na fydd yr elfennau gweddilliol yn cael eu dadansoddi.
③. Pan ddefnyddir ffwrnais asid i gynhyrchu castiau, rhaid i'r ddau barti gytuno ar gynnwys S a P.

Nodyn: 1. Y rhif mewn cromfachau yw'r rhif traddodiadol.2. Cynnwys elfennau gweddilliol: Ni 0.30 y cant , Cr 0.30 y cant , Cu { {10}}.25 y cant , Mo 0.15 y cant , V 0.05 y cant, cyfanswm yr elfennau gweddilliol 1 y cant. Os nad oes gan y sawl sy'n mynnu unrhyw ofynion, ni fydd yr elfennau gweddilliol yn cael eu defnyddio fel sail ar gyfer derbyn.
