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

Monday, May 7th, 2012

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 ASTM F899 2011 Edition on Wrought Stainless Steels for Surgical Instruments

Thursday, May 19th, 2011

New ASTM F899:2011, “Standard Specification for Wrought Stainless Steels for Surgical Instruments,” has just been released.  The document covers the chemistry requirements for wrought stainless steels used for the manufacture of surgical instruments.

Classes of stainless steels covered are Class 3 (austenitic stainless steel), Class 4 (martensitic stainless steel), Class 5 (precipitation hardening stainless steel), and Class 6 (ferritic stainless steel).  The data contained in this specification are for reference only and include typical hardness values, common heat treating cycles, and examples of selected stainless steels that have been used for surgical instruments.  Mechanical property, heat treatment, hardness, and all other requirements except for chemical composition, are governed by the appropriate material standards as specified or as agreed upon between purchaser and supplier.

Previous editions of ASTM-F899 include ASTM F899:2010, ASTM F899:2009(e1), ASTM F899:2009, ASTM F899:2007, ASTM F899:2002, ASTM F899:1995, ASTM F899:1994, ASTM F899:1984.  All these editions, and all ASTM standards, can be purchased from Document Center Inc. using our website, www.document-center.com.  Or contact us by phone (650-591-7600), fax (650-591-7617) or email (info@document-center.com).  We’re happy to assist you with all your standards needs.

New ASTM A240 2010A Edition Released

Friday, November 12th, 2010

ASTM A240 / A240M – 10a, Standard Specification for Chromium and Chromium-Nickel Stainless Steel Plate, Sheet, and Strip for Pressure Vessels and for General Applications, has just been released by ASTM International. The standard is a widely used specification for Chromium and Chromium-Nickel Stainless Steel.

It covers chromium, chromium-nickel, and chromium-manganese-nickel stainless steel plate, sheet, and strip for pressure vessels and for general applications. The steel described by the standard shall conform to the requirements as to chemical composition specified. Additionally, it shall conform to the mechanical properties specified.

The document features both inch-pound and metric measurements. This is notated in the document number (the A240/A240M means A240 inch-pound units/A240 Metric units).

All current ASTM standards and many obsolete revisions are available from Document Center Inc. on the website www.document-center.com, and by phone (650-591-7600), fax (650-591-7617) and email (info@document-center.com).
