Applicable procurement specifications are listed in Section 5. The alloy has a somewhat higher work hardening rate than carbon steel, but not as ashm as stainless steel. Link to Active This link will always route to the current Active version of the standard.
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:. Heavier than normal drafts may be required. A hardness indicated by tests made at a location shown in Fig. Close this window and log in. Minimum B As-Quenched Hardness. Link to Active This link will always route to the current Active version of the standard.

How can you prepare a quality bid when ASTM A is called out for steel composition and mechanical properties?? The alloy is used extensively in many corrosive applications especially in the marine and chemical processing industries.
It is resistant to chloride stress corrosion cracking and has high strength and toughness over a wide range of temperatures. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. Working at lower temperatures will result in higher mechanical properties and smaller grain size. The Eng-Tips staff will check this out and take appropriate action.
Historical Version s – view previous versions of standard. The alloy has been found to offer exceptional resistance to hydrofluoric acid in all concentrations up to the boiling point. Fabrication Data Alloy is readily fabricated by conventional processing operations. Thank you for helping keep Eng-Tips Forums free from inappropriate posts.
This is not a specification for the procurement of steel. Join your peers on the Internet’s largest technical engineering professional community. The choice of welding product is dependent upon the materials being welded and the environment in which it occurs.
I don’t have the specification. 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.
Cold working should be performed on annealed material.

A hardness indicated by tests made at a location shown in Fig. Bars cold-finished by turning, grinding, turning and polishing, etc.
Alloy Corrosion Resistant Nickel Alloy Plate – Sandmeyer Steel
Note 4—Steels having a maximum carbon content of 0. Test specimens immersed in solution in storage tank.
Resources Digital Transformation may be defined in a number of different ways by analysts or enterprise software vendors. Alloyin the annealed condition, exhibits moderate strength.
The alloy is also available in the as-rolled condition Alloy AR which imparts higher strength to the w400. However, under stagnant conditions, the alloy can encounter crevice and pitting corrosion. Are you an Engineering professional? Request Quote Contact Us.
Thickness of Flat Sections, in. D These steels have insufficient hardenability for Class Q-4 parts because of different location of test specimens, but are satisfactory for smaller sections. If the desired mechanical properties are as 4a00 forth in 4. Alloy is readily fabricated by conventional processing operations. Physical Properties Density 0. The alloy exhibits very low rates of corrosion in flowing sea or brackish water. Note 1—Steels listed as approved for a certain section or strength may asmt used for lighter sections and lower strengths.
