A hardness indicated by tests made at a location shown in Fig. An additional application area of the material is in marine environments and other nonoxidizing chloride solutions. Thank you for helping keep Eng-Tips Forums free from inappropriate posts. Alloy can be welded to itself or dissimilar metals by utilizing conventional welding processes. 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.

Those in italics are no longer considered standard grades due to decreased usage. Download Now White Paper: This is not a specification for the procurement of steel.

Steels with lower alloy contents are often satisfactory through the use of special processing techniques. Alloy is one of the most widely used materials for marine applications, shipbuilding and seawater desalination plants. It has outstanding resistance to neutral and alkaline salts and has been utilized for many years as a material of construction for salt plants.


It would not be cost effective to buy a spec just to bid the job. The alloy is also available in the as-rolled condition Alloy AR which imparts higher strength to the alloy. Promoting, selling, recruiting, coursework and thesis posting is forbidden.

Alloy Corrosion Resistant Nickel Alloy Plate – Sandmeyer Steel

The choice of welding product is dependent upon aztm materials being welded and the environment in which it occurs. Cold working should be performed on annealed material. Join your peers on the Internet’s largest technical engineering professional community.

Welding Alloy can be welded to itself or dissimilar metals by utilizing conventional welding processes.

Normal good shop practices are assumed, with control of austenitizing and tempering temperatures, and mild agitation of the part in the quenching bath.

Resources Digital Transformation may be defined in a number of different ways by analysts or enterprise software vendors. Alloy AR is stocked in thicknesses from. You have this information in the ASTM specification, see below 4.

Alloy is readily fabricated by conventional processing operations. The criteria for placing a steel composition in one of the three a40 class designations, Classes P, Q, and R described in Section 4 are as follows: I don’t have the specification.

Referenced Documents purchase separately The documents listed below are astn within the subject standard but are not provided as part of the standard.

The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. Only cold-drawn series steels used in the strength level and section 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. D These steels have insufficient hardenability for Class P-4, because of difference in test locations, but are satisfactory for other smaller sizes.

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. The alloy has a somewhat higher work hardening rate than carbon steel, but not as high as stainless steel.

Astn 1—Steels listed as approved for a certain section or strength may be used for lighter sections and lower strengths. Available thicknesses for Alloy
