ASTM A276/A276M, “Standard Specification for Stainless Steel Bars and Shapes,” has been updated. The new 2016 Edition has just been released and it replaces all earlier editions, including the previous 2015 Edition from January 2015. This is an essential standard covering hot- or cold-finished stainless steel bars and shapes. Reforging and free-machining types are not included.
As with all ASTM standards with a dual designation (A276 and A276M), the specification provides you with measurements both in inch-pound and SI units. Since values are not exact equivalents in moving from one to the other, you will need to be consistent in which measurement system to use.
The specification is divided into two major sections, each with it’s own table. First comes the chemical requirements, listed by UNS numbers. This gives you the percentage of the various metals that compose each UNS metal alloy type. Table two provides you with the mechanical requirements, again listed by UNS number. A short Table 3 covers the response to heat treatment. And of course, there’s the balance of the technical information — ordering information, manufacture, magnetic permeability, certification and the like.
Those of you who use the ASTM A276/A276M will want to know where to find the changes. Your committee A01 has provided you with a “Summary of Changes” at the end of the publication. This is your guide to where to look for your updates.
First, there is a new UNS type added to both Tables 1 and 2. You’ll find this also in section 22.214.171.124 as a stabilized anneal condition. There is also a new footnote K in Table 1. And another revision to Table 1 has been made to Grade S32750 (the additional of footnote L).
Of course, if you use this specification you’ll want a copy of the new 2016 Edition. You can purchase it in paper format or for pdf download at the Document Center Inc. webstore, www.document-center.com. Here is the direct link to the ASTM A276/A276M order page.
