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

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

Test specimens immersed in solution in storage tank. The alloy has a somewhat higher work hardening rate than carbon steel, but not as high as stainless steel. Hot-rolled series steels with a maximum carbon content of 0. It is resistant to chloride stress corrosion cracking and atm high strength and toughness over a wide range of temperatures.

Working at lower temperatures will result in higher mechanical properties and smaller grain size. Physical Properties Density 0. Alloyin the annealed condition, exhibits moderate strength. Alloy is one of the most widely used materials for marine applications, shipbuilding and seawater desalination plants. Close this window and log in. Note 3—An H-steel with the same grade designation as a standard SAE-AISI steel is capable of meeting the same section and strength requirements as the standard aatm see Specification Aand is the preferred method of specification.

Those in italics are no longer considered standard grades due to decreased usage. Alloy UNS N is a nickel-copper alloy with zstm resistance to a wide range of corrosive environments. Thickness of Flat Sections, in. Alloy is a relatively soft material that is z400 to hot forming into almost any shape. The choice of welding product is dependent upon the materials being welded and the environment in which it occurs.

It’s easy to join and it’s free. I would not have asked the question if I had the spec. By joining you are opting in to receive satm. Bars cold-finished by turning, grinding, turning and polishing, etc. 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 assumed, a4000 control of austenitizing and tempering temperatures, and mild agitation of the part in the quenching bath.

Available thicknesses for Alloy Thanks for the reply.

The applicable section sizes, identified as Classes Q-1 through Q-7, are shown in Table 7.

A hardness indicated by tests made at a location shown in Fig. Note 4—Steels having a maximum carbon content of 0.

Alloy Technical Information

Minimum B As-Quenched Hardness. 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.

This application would use a 4. Link to Active This link will always route to the current Active version of the standard. This is not a specification for the procurement of steel. Alloy AR is produced in the as-rolled condition to meet higher strength requirements. The Eng-Tips staff will check this out and take appropriate action.

Defense manufacturing is all about project manufacturing and project accounting.

Alloy 400/400AR

Alloy can be welded to itself or dissimilar metals by utilizing asrm welding processes. 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: Equivalent Tensile Strength, psi A.
