This application would use a 4. It has outstanding resistance to neutral and alkaline salts and has been utilized for many years as a material of construction for salt plants. The alloy is most frequently specified in environments ranging from mildly oxidizing through neutral and in moderately reducing conditions.

Alloy 400/400AR

Alloy AR is produced in the as-rolled condition to meet higher strength requirements. The alloy is used extensively in many corrosive applications especially in the marine and chemical processing industries.

Physical Properties Density 0. D These steels have insufficient hardenability for Class P-4, because of difference in test locations, but are satisfactory for other smaller sizes. Equivalent Yield Strength, psi A. Those in italics are no w400 considered standard grades due to decreased usage. The locations for obtaining tension tests are described in 6.

Welding Alloy can be welded to itself or dissimilar metals by utilizing conventional welding processes. Defense manufacturing is ashm about project manufacturing and project accounting.

Alloy is one of the few materials that will withstand contact with fluorine, hydrofluoric acid, hydrogen fluoride or their derivatives. Join your peers on the Internet’s largest technical engineering professional community. It exhibits resistance to corrosion in many reducing environments, and it is generally more aztm than higher copper alloys to oxidizing media. The alloy has a somewhat higher work hardening rate than carbon steel, but not as high as stainless steel. The choice of welding product is dependent upon the materials being welded and the environment in which it occurs.

Applicable procurement specifications are listed in Section 5.

The alloy exhibits very low rates of corrosion in flowing sea or brackish water. Normal good shop practices are assumed, with control of austenitizing and tempering temperatures, and mild agitation of the part in the quenching bath.

It is resistant to chloride stress corrosion cracking and has high strength and toughness over a wide range of temperatures. The applicable section sizes, identified as Classes Q-1 through Q-7, are shown in Table 7. An additional application area of the material is in marine environments and other nonoxidizing chloride solutions.
