The choice of welding product is dependent upon the materials being welded and the environment in which it occurs. 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: Alloy is one of the few materials that will withstand contact with fluorine, hydrofluoric acid, hydrogen fluoride or their derivatives.

S400 criteria for placing a steel composition in one of the three s400 class designations, Classes P, Q, and R described in Section 4 are ashm follows:. Normal good shop practices are assumed, with control of austenitizing and tempering temperatures, and mild agitation of the part in the quenching bath. Applicable procurement specifications are listed in Section 5. Alloy is a very versatile corrosion resistant material. 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.

Those in italics are no longer considered standard grades due to decreased usage. An additional application area of the material is in marine environments and other nonoxidizing a00 solutions. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

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

However, under stagnant conditions, the alloy can encounter crevice and pitting corrosion. It is resistant to chloride stress corrosion cracking and has high strength and toughness over a wide range of temperatures.

It would not be cost effective to buy a spec just to bid the job.

A hardness indicated by tests made at a location shown in Fig. Are you an Engineering professional? Bars cold-finished a040 turning, grinding, turning and polishing, etc. Close this window and log in. 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:. Resources Digital Transformation may be defined in a number of different ways by analysts or enterprise software vendors.

Alloy Corrosion Resistant Nickel Alloy Plate – Sandmeyer Steel

Applicable procurement specifications are listed in Section 5. Steels with lower alloy contents are often satisfactory through the use of special processing techniques. The cost of the standard is below, http: Note 3—An H-steel with the same grade designation as a standard SAE-AISI steel is capable a4000 meeting the same section and strength requirements as the standard steel see Specification Aand is the preferred method of specification.

Alloy AR is produced in the as-rolled condition to meet higher strength requirements. Click Here to join Eng-Tips and talk with other members! A hardness indicated by tests made at a location shown in Fig. Equivalent Yield Strength, psi A.

Alloy 400/400AR

Nickel plus Cobalt D These steels have insufficient hardenability for Class Q-4 parts because of different location of test specimens, but are satisfactory for smaller sections.

Note 1—Steels listed as approved for a certain section or strength may be used for lighter sections and lower strengths. Heavier than normal drafts may be required. Hot-rolled series steels with a maximum carbon content of 0.

Alloy AR is stocked in thicknesses from. Red Flag This Post Please let us know here why this post is inappropriate. The alloy is most frequently specified in environments ranging from mildly oxidizing through neutral and ast, moderately reducing conditions. Alloy is readily cold worked by virtually asym cold fabrication methods. Historical Version s – view previous versions of standard.

How can you prepare a quality bid when ASTM A is called astk for steel composition and mechanical properties?? It exhibits resistance to corrosion in many reducing environments, and it is generally more resistant than higher copper alloys to oxidizing media.

Alloy can be machined at standard rates with conventional machine tools. I am trying to bid a job and this is the callout for the material. Steels with lower alloy contents are often satisfactory through the use of special processing techniques.
