    Rationale

    (1) Since the last revision the twin rolling process has developed and is currently producing grade 100 (690) class 1 and class 2 material. Table 1, chemical requirements, and 5, mechanical requirements need to have these two products added. (2) The current revision of table 5 incorrectly lists grade 80 class 1 having a min tensile value of 90 ksi, 620 MPa. This was an oversight and is only appropriate for HSLA class 2. The correction should list the tensile value of HSLA class 1 at 95 ksi, 655 MPa.(3)Table X2.1 Suggested Minimum Inside Radius for Cold Bending also needs to have grade 100 added.
