Applications suggested for the materials are described only to help readers make their own evaluations and decisions, and are neither guarantees nor to be construed as express or implied warranties of suitability for these or other applications. Historical Version s – view previous versions of standard. Steels with lower alloy contents are often satisfactory through the use of special processing techniques. The alloy has been found to offer exceptional resistance to hydrofluoric acid in all concentrations up to the boiling point.

Nickel plus Cobalt Available thicknesses for Alloy This application would use a 4. Physical Properties Density 0. Active view current version of standard.

Alloy UNS N is a nickel-copper alloy with excellent resistance to a wide range of corrosive environments. Alloy also resists sulfuric and hydrochloric acids under reducing conditions. Machining Alloy can be machined at standard rates with conventional machine tools. Alloy can be welded to itself or dissimilar metals by utilizing conventional welding processes.

ASTM A Class Q2 – Metal and Metallurgy engineering – Eng-Tips

Steels with lower alloy contents atsm often satisfactory through the use of special processing techniques. Alloy is a relatively soft material that is receptive to hot forming into almost any shape. Working at lower temperatures will result in higher mechanical properties and smaller grain size.

An additional application area of the material is in marine environments and other nonoxidizing chloride solutions. Hot-rolled series steels with a maximum carbon content of 0.

Alloy is readily cold worked by virtually all cold fabrication methods.

Alloy 400/400AR

Only cold-drawn series steels used in the strength level and section thickness for which hot-rolled steels of the same composition are approved may be welded, and in this case caution should be exercised to see that excessive grain growth does not occur in the heat-affected zone.

The locations for obtaining tension tests are described in 6. Equivalent Tensile Strength, psi A. The cost of the standard is below, http: Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Applicable procurement specifications are listed in Section 5. D These steels have insufficient hardenability for Class Q-4 parts because of different location of test specimens, but are satisfactory for smaller sections.


It’s easy to join and it’s free. It exhibits resistance to corrosion in many reducing environments, and it is generally more resistant than higher copper alloys to oxidizing media.

Defense manufacturing is all about project manufacturing and project accounting. A hardness indicated by tests made at a location shown in Fig. Alloy AR is stocked in thicknesses from. Students Click Here Join Us! Cold working should be performed on annealed material. The applicable section sizes, identified as Classes Q-1 through Q-7, are shown in Table 7.

I don’t have the asttm. The alloy has a somewhat higher work hardening rate than carbon steel, but not as high as stainless steel. Fabrication Data Alloy is readily a040 by conventional processing operations. Alloy UNS N is a ductile nickel-copper alloy with resistance to a variety of awtm conditions. Alloy AR is produced in the as-rolled condition to meet higher strength requirements. How can you prepare a quality bid when ASTM A is called out for steel composition and mechanical properties??

Alloy resists stress corrosion cracking and pitting in most fresh and industrial water applications.
