MIL-E-22200/2D

Abstract

This specification covers shielded metal arc welding covered electrodes, for manually depositing austenitic chromium-nickel steel weld metal. The use of this specification is limited to the acquisition of electrodes for the following applications: <br>(a) Subsafe. <br>(b) HY-80 steel welded to austenitic stainless steel for submarines and surface ships. <br>(c) Other special applications when approved or specified by the command or agency concerned. <br>Applicable American Welding Society specifications are used for other applications of these types of electrodes. <b><u>Intended Use:</u></b> These electrodes are intended for the general welding of 18 percent chromium, 8 percent nickel, corrosion-resistant (stainless) steels. These electrodes are intended for the welding applications of 6.1.1 requiring a limited cobalt content. These electrodes are intended for the general welding of 18 percent chromium, 8 percent nickel extra low carbon corrosion-resistant steel, used where intergranular corrosion should be limited but where corrosive conditions are not the most severe. These electrodes are intended for the welding applications of 6.1.3 requiring a limited cobalt content. These electrodes are intended for applications where low magnetic permeability is of prime importance and where corrosion is not a factor. These electrodes are intended for the joining of the 18-8 grades of corrosion-resistant steel to mild steel; special treatment steel, class B armor and other low alloy air-hardening steels, when specified; and carbon and straight chromium steels to austenitic grades. These electrodes are also for deposition of a corrosion-resistant overlay on carbon and low alloy steels. These electrodes are intended for the welding applications of 6.1.6 requiring a limited cobalt content. These electrodes are intended for similar applications as MIL-309-15 and 16 types, but where added resistance to intergranular corrosion is desired. These electrodes are intended for the welding applications of 6.1.8 requiring a limited cobalt content. These electrodes are intended for similar applications as the MIL-309-15 and 16 types, but where expected corrosive conditions are more severe, or higher strength at elevated temperature is desirable. These electrodes are intended for the welding of 25 percent chromium, 20 percent nickel heat-resistant alloy steels used in high temperature service; special treatment steel, class B armor, and other low-alloy air-hardening steels, where specified; and carbon and straight chromium steels to austenitic grades. These electrodes are also intended for deposition of a corrosion-resistant overlay on carbon and low alloy steels. These electrodes are intended for the joining of the super-alloys to low-alloy (chromium-molybdenum and chromium-nickel-molybdenum) steels. These electrodes are intended for the joining of corrosion-resistant alloys of similar designations. The molybdenum content imparts increased resistance to the corrosive effect of many organic acids, brine, sulfurous, and sulfuric acid. These electrodes are intended for the welding of type 316L corrosion-resisting steel and under conditions similar to those under which type MIL-318 could be used. These electrodes are intended for welding of alloys of similar composition for increased corrosion-resistance to sulfuric and sulfurous acid and their salts. These electrodes are intended for the welding of type 318 corrosion-resisting steel. Generally, uses are similar to those of type MIL-316 electrode, except that, where elevated temperatures and corrosive conditions favor intergranular corrosion and type 318 alloy is used, choice of stabilized type MIL-318 electrode is indicated. These electrodes are used in repair of alloy castings and welding of cast and wrought alloys of similar compositions which are generally used for heat-resisting properties of high temperatures. These electrodes are intended for the general welding of 18-8 corrosion-resisting steels stabilized by columbium, which are used where conditions of welding or service make unstabilized base metals susceptible to carbide precipitation, with consequent intergranular corrosion. Use of these electrodes will not prevent intergranular corrosion alongside a weld in unstabilized 18-8 chromium-nickel base metals. These electrodes are intended for the welding applications of 6.1.18 requiring a limited cobalt content. These electrodes are intended for applications where low magnetic permeability or heat resistance is of prime importance and where corrosion is not a factor. These electrodes are intended for the joints of the super-alloys for applications requiring high strength at elevated temperatures. These electrodes are intended for use in welding 316, 317, and 347 alloys for corrosion-resisting and high temperature service in the as-welded or stress-relieved condition. <br>
