Heat Treatment of Carbon and Low-Alloy Steel Parts Minimum Tensile Strength Below 220 ksi (1517 MPa)
This specification, in conjunction with the general requirements for steel heat treatment covered in AMS2759, establishes the requirements for heat treatment of carbon and low-alloy steel parts to minimum ultimate tensile strengths below 220 ksi (1517 MPa). Parts are defined in AMS2759. Due to limited hardenability in these materials, there are size limits in this specification.
AMS2759/1J adds clarification to surface contamination (126.96.36.199) and to periodic test (4.2) regarding Type 1 parts; adds reference to a new note 8.6 in surface contamination (188.8.131.52); separates hardness and surface contamination in acceptance tests (4.1); adds reference to new note 8.7 in acceptance tests (4.1); adds new notes 8.6 and 8.7; updates Tables 2 and 3 to include specific alloys that were listed in Table 6, but inadvertently left out; corrects Table 4 to delete a line separating alloys that should not have been there; corrects Table 6 by moving 4137 to be in line with 4135 and 8735.
