Normal good shop practices are assumed, with control of austenitizing atsm tempering temperatures, and mild agitation of adtm part in the quenching bath. If the desired mechanical properties are as set forth in 4. 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 Yield Strength, psi A.

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. Per the stated strength levels, I see that HT per A could work, but I can’t be sure without more info. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

Note 4—Steels having a maximum carbon content of 0. Active view current version of standard. Alloy can be welded to itself or dissimilar metals by utilizing conventional welding processes.

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 aastm.

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. It’s easy to join and it’s free. Equivalent Tensile Strength, psi A. Alloy is one of the few materials that will withstand contact with fluorine, hydrofluoric acid, hydrogen fluoride or their derivatives. Link to Active This link will always route to the current Active version of the standard.

The Eng-Tips staff will check this out and take appropriate action. Note 1—Steels listed as approved for heavier section or higher strengths ashm be used in the same conditions for lighter sections and lower strengths.

Defense manufacturing is all about project manufacturing and project accounting. Thickness of Flat Sections, in.

Alloy can be machined at standard rates with conventional machine tools. The locations for obtaining tension tests are described in 6. Fabrication Data Alloy is readily fabricated by conventional processing operations. Hot Working Alloy is a relatively soft material that is receptive to hot forming into almost any shape.

Download Now White Paper: Alloy is a very versatile corrosion resistant material. 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:. Thank you for helping keep Eng-Tips Forums free from inappropriate posts. Alloy is a relatively soft material that is receptive to hot forming into almost any shape. Heavier than normal drafts may be required. A hardness indicated by tests made at a location shown in Fig.

How can you prepare a quality bid when ASTM A is called out for steel composition and mechanical properties?? Steels with lower alloy contents are often satisfactory through the use of special processing techniques. Applicable procurement specifications are listed in Section 5. This application would use a 4.

Alloy Technical Information

Alloy UNS N is a ductile nickel-copper alloy with resistance to a variety of corrosive conditions. Note 5—Parts made of steel with a carbon content of 0. Nickel plus Cobalt 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 steel see Specification Aand is the preferred method of specification.

Alloy AR is x400 in thicknesses from. Alloy is readily fabricated by conventional processing operations. Marine Components — shipbuilding, valves, pumps, shafts and in sea and brackish water Oil and Gas Production — splash-zones for offshore structures and sour gas applications Ore Processing — uranium refining and separation in the production of nuclear fuels Petroleum Refining — alkylation units, crude petroleum stills, piping and storage tanks Power Generation — feed-water heaters and steam generators Water W400 — brine heaters and evaporators in seawater desalination plants.
