The following standard is the part 1 of the BS3100 1991. Including Grade A1, A2, A3, A4, A5, A6, AL1, AL2, AL3, BL2, AM1, AM2, AW1, AW2, AW3. It is the chemical composition limits for the cast analysis of carbon, carbon manganese and low alloy steel castings. This is a British standard. Our foundry can produce all materials in this standard.
