New ASTM A580/A580M 2012 Edition, Standard Specification for Stainless Steel Wire

ASTM A580/A580M, 2012 Edition, “Standard Specification for Stainless Steel Wire,” has just been released and is now available from Document Center Inc.  The document was editorially corrected within weeks, so that the new correct edition is the ASTM A580/A580M-12(e1) Edition.

This specification covers stainless steel wire, except the free-machining types. It includes round, square, octagon, hexagon, and shape wire in coils only for the more commonly used types of stainless steels for general corrosion resistance and high-temperature service.

ASTM A580/A580M steel specimens undergo the following conditions: (1) annealed as a final heat treatment; (2) cold worked to higher strength; (3) heat treated to an intermediate temper; or (4) heat treated to a hard temper by austenitizing, quenching, and tempering at a relatively low temperature.  The materials are cold drawn, annealed, and pickled.

The steel wires are expected to conform to the required chemical compositions of carbon, manganese, phosphorus, sulfur, silicon, chromium, nickel, molybdenum, nitrogen, and other elements such as niobium , vanadium, copper, tantalum, titanium and cobalt as defined in Table 1.

Table 2 covers mechanical test requirements that verify that the steel specimens conform to the required values of tensile strength, yield strength, and elongation. The martensitic grades conform to the required values of hardness after heat treatment.

The original changes to the standard include the addition of new grades to both table 1 and table 2.  The editorial change that followed corrected Table 2 only.

New MIL-STD-1130 Revision C, “Connections, Electrical, Solderless Wrapped,” replaces MIL-STD-1130B

The U.S. Defense Department released the new Revision C for MIL-STD-1130, “Connections, Electrical, Solderless Wrapped.”  The 21 page standard replaces MIL-STD-1130B and is now available from Document Center Inc.  The document identifies the requirements for proper wire wrapping techniques to ensure adequate connection between wire and wrappost terminations for military wire wrap connector applications.

The standard was actually canceled in 1999 and only reinstated on August 16, 2010.  This new revision is the first change to the standard since that time.

MIL-STD-1130C establishes the requirements to produce mechanically and electrically stable, solderless wrapped, electrical connections made with single, solid, round wire and appropriately designed wrapposts (terminals).

This standard includes:
a. Classes and requirements for solderless wrapped connections.
b. Description and requirements for the wire used in making the solderless wrapped connections.
c. Description and requirements for the wrappost used in making the solderless wrapped connections.

MIL-STD-1130 also covers the following classes of solderless wrapped, electrical connections:
Class A – Solderless wrapped, electrical connections.
Class B – Conventional solderless wrapped, electrical connections. FYI: Class A will be used whenever possible.

Changes in the new revision are extensive, so there’s no notation in the margins of the new standard to highlight areas where revisions were made.
