SPCC Commercial quality is the most widely used of all cold rolled steel products and is best suited for moderate forming or drawing Household electrical appliances, furniture, drums, automotive parts, base metal for galvanized sheets and other coated products. CR1 CR1 Bj DC SPCC
SPCD Drawing quality features chemical composition and mechanical properties. It is suited to applications where drawing is involved. Automotive parts, household, oil filters, electrical appliances. CR2 CR2 Bj DD1 SPCD
SPCE Deep drawing properties and uniform quality features. Non intricate deep drawing parts. CR3 CR3 Bj DD2 SPCE
SPCF Steel of this quality is specially killed and has as extremely uniform grain structure. This makes it particularly suitable for the manufacture of parts requiring severe and intricate deep drawing with a non-ageing quality. Furthermore, steel of this quality is free from stretcher-strain, even after prolonged storage. Automotive bodies and parts, eletrical machinery parts, other products requiring intricate drawing. CR4 CR4 Bj DD3 SPCEN
SPCG Extra deep drawing non-ageing quality is excellent in formability and is suitable for complicated deep drawing. Automobile outer panels, fenders, hoods, complicated floor boards, oil sump tanks, etc. CR5 CR5 - -
