Alloy 400/400AR

I would not have asked the question if I had the spec. Equivalent Yield Strength, psi A. The locations for obtaining tension tests asttm described in 6.

The criteria for placing a steel astj in one of the three general class designations, Classes P, Q, and R described in Section 4 are as follows: Note 1—Steels listed as approved for heavier sections or higher strengths may be used in the same conditions for lighter sections and lower strengths. Thickness of Flat Sections, in.

Hot Working Alloy is a relatively soft material that is receptive to hot forming into almost any shape. Digital Transformation may be defined in a number of different ways by analysts or enterprise software vendors. Register now while it’s still free! Applicable procurement specifications are listed in Section 5. Note 5—Parts made of steel with a carbon content of 0.


Alloy is a relatively soft material that is receptive to hot forming into almost any shape. The information and data in this product data sheet are accurate to the best of our knowledge and belief, but are intended for informational purposes only, and may be revised at any time without notice.

An additional application area of the material is in marine environments and other nonoxidizing chloride solutions. However, under stagnant conditions, the alloy can encounter crevice and pitting corrosion. Nickel plus Cobalt Steels with lower alloy contents are often satisfactory through the use of special processing techniques.

The Eng-Tips staff will check this out and take appropriate action. Defense manufacturing is all about project manufacturing and project accounting. Ast, for the reply. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

This application would use a 4. Only cold-drawn series steels used in the strength level and section thickness for which hot-rolled steels of the same composition z400 approved may be welded, and in this w400 caution should be exercised to see that excessive grain growth does not occur in the heat-affected zone. Normal good shop practices are assumed, with control of austenitizing and tempering temperatures, and mild agitation of the part in the quenching bath.

Alloy can be welded to itself or dissimilar metals by utilizing conventional welding processes. The alloy is most frequently specified in environments ranging from 4a00 oxidizing through neutral and in moderately reducing conditions. Applicable procurement specifications are listed in Section 5. Are you an Engineering professional? It exhibits resistance to corrosion in many reducing environments, and it is aa400 more resistant than higher copper alloys to oxidizing media.


Physical Properties Density 0. Alloy is one of the few materials that will withstand contact with fluorine, hydrofluoric acid, hydrogen fluoride or their derivatives. The alloy has been found to offer exceptional resistance to hydrofluoric acid in all concentrations up to the boiling point. Request Quote Contact Us.

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

Alloy is a very versatile corrosion resistant material. Equivalent Tensile Strength, psi A. Thank you for helping keep Eng-Tips Forums free from inappropriate posts. The applicable section sizes, identified as Classes Q-1 through Q-7, are shown in Table 7.

Alloy UNS N is a ductile nickel-copper alloy with resistance to a variety of corrosive asstm. I don’t have the specification.
