Steels with lower alloy contents are often satisfactory through the use of special processing techniques. Are you an Engineering professional? Link to Active This aa400 will always route to the current Active version of the standard.

Equivalent Yield Strength, psi A. Alloyin the annealed condition, exhibits moderate strength. A hardness indicated by tests made at a location shown in Fig. Thank you for helping keep Eng-Tips Forums free from inappropriate posts. Cold working should be performed on annealed material. Note 1—Steels listed as approved for a certain section or strength may be used for lighter sections and lower strengths.

Alloy Technical Information

Hot-rolled series steels with a maximum carbon content of 0. Close this window and log in. Click Here to join Eng-Tips and talk with other members!

Normal good shop practices are assumed, with control of austenitizing and tempering temperatures, and mild agitation of the part in ashm quenching bath. Active view current version of standard.

Alloy Corrosion Resistant Nickel Alloy Plate – Sandmeyer Steel

Alloy is one of the few materials that will withstand contact with fluorine, hydrofluoric acid, hydrogen fluoride or their derivatives.

It’s easy to join and it’s free. Alloy resists stress corrosion cracking and pitting in most fresh and industrial water applications.


I don’t have the specification. Applicable sstm specifications are listed in Section 5. Join your peers on the Internet’s largest technical engineering professional community. Note 3—An H-steel with the same a040 designation as a standard SAE-AISI steel is capable of meeting the same section and strength requirements as the standard steel see Specification Aand is the preferred method of specification.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Working at lower temperatures will result asmt higher mechanical properties and smaller grain size. It is resistant to chloride stress corrosion cracking and has high strength and toughness over a wide range of temperatures.

D These steels axtm insufficient hardenability for Class P-4, because of difference in test locations, but are satisfactory for other smaller sizes. Download Now Defense manufacturing is all about project manufacturing and project accounting.

The applicable section sizes, a40 as Classes Q-1 through Q-7, are shown in Table 7. Alloy UNS N is a nickel-copper alloy with excellent resistance to a wide range of corrosive environments. The alloy is most frequently specified in environments ranging from mildly oxidizing through neutral and in moderately reducing conditions. Historical Version s – view previous versions of standard. Alloy AR is produced in the as-rolled condition to meet higher strength requirements.

4a00 Applications suggested for the materials are described only astj 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.

The criteria for placing a steel composition in one of the three general class designations, Classes P, Q, and R described in Section 4 are as follows: The steel compositions suitable for Classes Q-1 through Q-7 and various desired mechanical properties are listed in Tables 3 and 4.


The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

The Eng-Tips staff will check this out and take appropriate action.

Reasons such as off-topic, duplicates, flames, asrm, vulgar, or students posting their homework. Applicable procurement specifications are listed in Section 5. Alloy can be machined at standard rates with conventional machine tools. Welding Alloy can be welded to itself or dissimilar metals by utilizing conventional welding processes.

It would not be cost effective to buy a spec just to bid the job.

Alloy 400/400AR

Physical Properties Density 0. Steels with lower alloy contents are often satisfactory through the use of special processing techniques. Available thicknesses for Alloy Note 1—Steels listed as approved for heavier section or higher strengths a00 be used in the same conditions for lighter sections and lower strengths. The alloy has been found to offer exceptional resistance to hydrofluoric acid in all concentrations up to the boiling point.

By joining you are opting in to receive e-mail. The alloy is used extensively in many corrosive applications especially in the marine and chemical processing industries. I would not have asked the question if I had the spec. How can you prepare a quality bid when ASTM A is called out for steel composition and mechanical properties?? Nickel plus Sstm Minimum B As-Quenched Hardness.

The choice of welding product is dependent upon the materials being welded and the environment in which it occurs.
