    Rationale

    This revision changes Yield Point in Table S14.1 to Yield Strength at 0.2% Offset. The alloys in this specification do not exhibit a yield point as defined by ASTM A370. Specifications A351/A351M and A608/A608M contain several of the same alloys and use Yield Strength. Grade HU in Table 1 use the lower-case letter L in 19Cr-39Ni. This has been editorially corrected to 19Cr-39Ni. Corrected the MPa conversion of 63 ksi in Table S14.1 for grade HP15Nb from 450 MPa to 435 MPa.
