Historical Version s – view previous versions of standard. You have this information in the ASTM specification, see below 4.
The locations for obtaining tension tests are described in 6. Per the stated strength levels, I see that HT per A could work, but I can’t be sure without more info. Alloyin the annealed condition, exhibits moderate strength. It has outstanding resistance to neutral and alkaline salts and has been utilized for many years as a 4a00 of construction for salt plants.
ASTM A Class Q2 – Metal and Metallurgy engineering – Eng-Tips
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: How can you prepare a quality bid when ASTM A is called out for steel composition and mechanical properties?? Alloy can be welded to itself or dissimilar metals by utilizing conventional welding processes.
Promoting, selling, recruiting, coursework and thesis posting is forbidden. The applicable section sizes, identified as Classes Q-1 through Q-7, are shown in Table 7.

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. This is not a specification for the procurement of steel. The Eng-Tips staff will check this out and take appropriate action.
Alloy is readily cold worked by virtually all cold fabrication methods. I am trying to bid a job and this is the callout for the material.
The alloy is used extensively in many corrosive applications especially in the marine and chemical processing industries. Equivalent Tensile Strength, psi A. Fabrication Data Alloy is readily fabricated by conventional processing operations. Those in italics are no longer considered standard grades due to decreased usage.
Applicable procurement specifications are listed in Section 5. I don’t have the specification. Close this window and x400 in. Equivalent Yield Strength, psi A.
aatm Resources Digital Transformation may be defined in a number of different ways by analysts or enterprise software vendors. Heavier than normal drafts may be required. 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:.
Download Now White Paper: Normal good shop practices are assumed, with control of austenitizing and tempering temperatures, and mild agitation of the part in the quenching bath. Alloy is one of the most widely used materials for marine applications, shipbuilding and seawater desalination plants. Note 4—Steels having a maximum carbon content of 0.
Alloy can be machined at standard rates with conventional machine tools.
Are you an Engineering professional? Applicable procurement specifications are listed in Section 5. Alloy is a relatively soft material that is receptive to hot forming into almost any shape. 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:. 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 Treatment — brine heaters and evaporators in seawater desalination plants.
