ASTM A / AM – 14e1 Standard Specification for Steel Castings Suitable for Pressure Service

Magnetic Particle Inspection S5. Preliminary heat treatment prior to nal heat treatment as well as multiple tempering is permitted.

Preliminary heat treatment and multiple tempering are permitted. Minimum temperature unless range is specied. The intermediate and nal PWHT temperatures shall be the same as the intermediate and nal tempering temperatures, respectively, as the original heat treatment of the castings.

Re—examination of the weld repair by radiography when Supplementary Requirement S astn has been specied will not be necessary when an applicable surface inspection method was used asym locate the discontinuity except for the following: Data sheets for overmetals, a47, ceramics, and composites. General Conditions for Delivery 3. Other surface discontinuities shall meet the visual acceptance standards specied in the order.

Combining values from the two systems may result in non-conformance with the standard. All castings shall receive the specified heat treatment requirement: Product analysis tolerances for stainless grades are not presently applicable pending development of these limits.
