cceptable subject to the following condition in addition to those conditions spe cified in the Code Case: Welding of age-hardenable alloy SA-453 Grade 660 and SA-637 Grade 688 should be performed when the material is in the solution treated condition. N-60-1 05-25-83 Material for Core Support 09-17-84 Structures, Section III, Divi sion 1 Code Case N-60-1 was acceptable subject to the following condition in addition to those conditions spe cified in the Code Case: Welding of age-hardenable alloy SA-453 Grade 660 and SA-637 Grade 688 should be performed when the material is in the solution treated condition. 18Code Case 1492 is no longer listed by ASME as a Section III Code Case and is therefore deleted from the acceptable listing 1.85-12 L N-60-2 09-17-84 Material for Core Support 09-05-85 Structures, Section III, Divi sion 1 Code Case N-60-2 was acceptable subject to the following condition in addition to those conditions spe cified in the Code Case: Welding of age-hardenable alloy SA-453 Grade 660 and SA-637 Grade 688 should be performed when the material is in the solution treated condition. For SA-479 material, the maximum yield strength should not exceed 90,000 psi in view of the susceptibility of this material to environmental cracking.
