Physical Properties Density 0. The locations for obtaining tension tests are described in 6.

Close this window and log in. It would not be cost effective to buy a spec just to bid the job. The alloy has a somewhat higher work hardening rate than carbon a4000, but not as high as stainless steel. The alloy has been found to offer exceptional resistance to hydrofluoric acid in all concentrations up to the boiling point. I would not have asked the question if I had the spec. If the desired mechanical properties are as set forth in 4.

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

Applicable procurement specifications are listed in Section 5. Red Flag This Post Please let us know here why this post is inappropriate. The criteria for placing a steel composition in one of the three general class designations, Classes Adtm, Q, and R described in Section 4 are as follows: Promoting, selling, recruiting, coursework and thesis posting is forbidden.

Alloy is a relatively soft material that is receptive to hot forming into almost any shape. Those in italics are no longer considered standard grades due to ashm usage. This is not a specification for the procurement of steel.

Alloy 400/400AR

Alloy is a very versatile corrosion resistant material. Applications Chemical Processing Equipment — in fluorine, hydrofluoric acid, hydrogen fluoride, hydrochloric acid, sulfuric acid, neutral and alkaline salt solutions, caustic alkalies, non-oxidizing halides and dry chlorine service. By joining you are opting in to receive e-mail. Fabrication Data Alloy is readily fabricated by conventional processing operations. This application would use a 4. It’s easy to join and it’s free.

Machining Alloy can be machined at standard rates with conventional machine tools. D These steels have insufficient hardenability for Class P-4, because of difference in test locations, but are satisfactory for other smaller sizes. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. The applicable section sizes, identified as Classes Q-1 through Q-7, are shown in Table 7.

Note 1—Steels listed as approved for a certain section or strength may be used for lighter sections and lower strengths. Nickel plus Cobalt Available thicknesses for Alloy Alloy can be machined at standard rates with conventional machine tools. Test specimens immersed in solution in storage tank.

The Eng-Tips staff will check this out and take appropriate action. Alloy is one of the few materials that will withstand contact with fluorine, hydrofluoric acid, hydrogen fluoride or their derivatives.

Normal good shop practices are 4a00, with control of austenitizing and tempering temperatures, and mild agitation of the part in the quenching bath. Alloy UNS Asrm is a ductile nickel-copper alloy with resistance to a variety of corrosive conditions.

Steels with lower alloy contents are often satisfactory through the use of special processing techniques. D These steels have insufficient hardenability for Class Q-4 parts because of different location of test specimens, but are satisfactory for smaller sections.
