Note 1—Steels listed as approved for heavier section or higher strengths may be used in the same conditions for lighter sections and lower strengths. 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.
D These steels have insufficient hardenability for Class Q-4 parts because of different location of test specimens, but are satisfactory for smaller sections. I am trying to bid a job and this is the callout for the material. Historical Version s – view previous versions of standard. Close this window and log in. This application would use a 4.
Alloy Corrosion Resistant Nickel Alloy Plate – Sandmeyer Steel
Thickness of Flat Sections, in. Normal good shop practices are assumed, with control of austenitizing and tempering temperatures, and mild agitation of the part in the asmt bath. Note 1—Steels listed as approved for a certain section or strength may be used for lighter sections and lower strengths.
Normal good shop practices are assumed, with control of austenitizing and tempering temperatures, and mild agitation of the part in the quenching bath. Working at lower temperatures will result in higher mechanical properties and smaller grain size.
The locations for obtaining tension tests are described in 6. Alloy is a relatively soft material that is receptive x400 hot forming into almost any shape. This is not a specification for the procurement of steel.
How can you prepare a quality ast, when ASTM A is called out for steel composition and mechanical properties?? Alloy is one of the most widely used materials for marine applications, shipbuilding and seawater desalination plants. The steel compositions suitable for Asym Q-1 through Q-7 and various desired mechanical properties are listed in Tables 3 and 4. Reasons such as off-topic, duplicates, flames, illegal, vulgar, or students posting their homework. Welding Alloy can be welded to itself or dissimilar metals by utilizing conventional welding processes.
It exhibits resistance to corrosion in many reducing environments, and it is generally more resistant than higher copper alloys to oxidizing media. I would not have asked the question if I had the spec.
Alloy resists stress corrosion cracking and pitting in most fresh and industrial water applications. Promoting, selling, asstm, coursework and thesis posting is forbidden. Hot Working Alloy is a relatively soft material that is receptive to hot forming into almost any shape.
Only cold-drawn series steels used in the strength level and astj 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.
Resources Digital Transformation may be defined in a x400 of different ways by analysts or enterprise software vendors.
Alloy can be welded to itself or dissimilar metals by utilizing conventional welding processes. The alloy is used extensively in many corrosive applications especially in the marine and chemical processing industries. Alloy can be machined at standard rates with conventional machine tools.
Fabrication Data Alloy is readily fabricated by conventional processing operations. The alloy is also available in the as-rolled condition Alloy AR which imparts higher strength to the alloy. D These steels have insufficient hardenability for Class P-4, because of difference in test locations, but are satisfactory for other smaller sizes. The cost of the standard is below, http: Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
Note 1—Steels listed as approved for heavier sections or higher strengths may be used in the same conditions for lighter sections and lower strengths. Applications suggested for the materials are described only to help readers make their own evaluations and decisions, and are neither guarantees nor to be construed as express or implied warranties of suitability for these or other applications.

It would not be cost effective to buy a spec just to bid the job. Minimum B As-Quenched Hardness. Download Now White Paper: 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 is a very versatile corrosion resistant material. Cold Working Alloy is readily cold worked by virtually all cold fabrication methods. Students Click Here Join Us! Heavier than normal drafts may be required. Alloy is one of the few materials that will withstand contact with fluorine, hydrofluoric acid, hydrogen fluoride or their derivatives. The choice of welding product is dependent upon the materials being welded and the environment in which it occurs.
