Tagraíonn A203 Grád B do chineál sonrach depláta cruach cóimhiotail nicil-i gcomhréir le caighdeán ASTM A203, a úsáidtear go príomha le haghaidh soithí brú táthaithe a oibríonn i dtimpeallachtaí íseal-teochta. Déantar idirdhealú a dhéanamh air ag a neart íosta toraidh de 275 MPa agus neart teanntachta níos mó ná 480 MPa, chomh maith le cion nicil 2.25%.
Tá toradh agus neart teanntachta A203 Grád B beagán níos airde ná A203 Grád A.
