Gauge: .004-.125 (inches) Width: .250-60 (inches)
ID: 16 or 20 (inches) standard OD: 78 (inches) maximum
Coil Weight: 40,000 pound maximum

Camber:

Over 1/2" to 1 1/2" (1/2" in any 8')
Over 1 1/2" to 24" (1/4" in any 8')

* Camber is to be determined by placing an 8ft. straight edge against the concave edge of the strip.

* Camber is the greatest deviation of the side edge from a straight line; the measurement being taken on the concave side with a straight edge.

* (1) When silicon is required, the following ranges and limits are commonly used:
                    Per Cent
Up to 1015, excl.        0.10 max.
1015 to 1025, incl.      0.10 max., 0.10-0.25 or 0.15-0.30
Over 1025                 0.10-0.25 or 0.15-0.30

* (2) The chemical compositions shown in this table are the same as shown in SAE J402b, 1977 except for AISI numbers 1006 and 1008. Formerly 1006 had a manganese range of .25-.45 and 1008 was shown with a .25-.50 range.
