Tá pláta cruach SA302GrB de chineál amháin cruach cóimhiotail moluibdín i ASME SA302/SA302M, tá SA302 Grád B comhionann go hiomlán leA302 Grád Bi sonraíocht cruach ASTM A302/A302.
Cur síos ar Tháirgí
Is pláta cruach cóimhiotal moluibdín mangainéise é A302 Grád B atá deartha go sonrach le haghaidh coirí táthaithe agus soithí brú eile. Úsáidtear é i dtionscail cosúil le peitriliam, ceimiceacha agus giniúint cumhachta chun trealamh a mhonarú mar imoibreoirí, malartóirí teasa agus umair stórála. Tá neart toraidh íosta de 345 MPa ag an ábhar agus neart teanntachta de 550-690 MPa.
Is é SA302 Grád B amangainéis-pláta cruach cóimhiotail moluibdín a úsáidtear le haghaidh coirí táthaithe agus soithí brú eile. Tá íos-neart toraidh aige de 345 MPa (50 ksi) agus neart teanntachta 550-690 MPa (80−100 ksi). De ghnáth soláthraítear an cruach i riocht rollta, cé gur féidir é a normalú nó faoiseamh ó strus má shonraítear é.
