ASME BOILER AND PRE.SSURE VESSEL CODE RELIEF REQUEST FOR SERVICE WATER PUMPS SALEM AND HOPE CREEK GENERATING STATIONS DOCKET NOS. 50-272, 50-311, AND 50-354 Public Service Electric & Gas Company (PSE&G) hereby requests relief from restrictions for welding on SA-351 material contained in the 1989 ASME Boiler and Pressure Vessel Code Section III.
This relief is requested to remove the welding restrictions contained in ASME Boiler and Pressure Vessel 1989 Code, Table I-7.2 (Attachment 1) for SA-351 material, Grade CD4MCu.
The 1989 restriction states:
"No welding is permitted on these Materials."
However, 1989 ASME Coda Section II (Attachment 2) is in conflict with this welding restriction.
Repairs by welding are permitted for all grades of SA-351.
In 1994, the ASME proposed to correct the error by the deletion of the welding restriction for SA-351, Grade CD4MCu.
By letter dated July 7, 1994, Item 94-137 recommends approval of the following change:
"SA-351, Type CD4MCu (cast material) is a weldable material, so deletion of note B2:(5), which does not permit welding, is appropriate." to ASME letter dated August 9, 1994 states that the change is approved.
The welding restriction will be deleted from the next (1994) edition of the ASME Code. to this l,etter contains the applicable pages from 1989 ASME Code Section III Table I-7.2. contains
. the applicable pages from 1989 ASME Code Section II.
Attachment 3 contains the 1994 letters from the ASME Code Committee intended to clarify the discrepancy.

When this amount of deformation is not acceptable, the designer should reduce the design stress to obtain an acceptable deformation. Table 1-2.4 lists multiplying factors which, when applied to the yield strength values shown on Table 1-2.2, will give an allowable stress that will result in lower levels of permanent strain.
(3) These S values do not include a longitudinal weld efficiency factor. For materials w~lded without filler metal, ultrasonic examination, radiographic examination, or eddy current examination, i.1 accordance with NC-2550, shall provide a longitudinal weld efficiency factor of 1.00.

SPECIFICATION FOR STEEL CASTINGS, AUSTENITIC, FOR HIGH-TEMPERATURE SERVICE SA-351/SA-35 lM (Identical with ASTM Specification A 351/A 351M-86 except for editorial differences in 10.1 and Table 2)
- 1. Scope 1.1 This specification covers austenitic steel castings for valves, flanges, fittings, and other pressure-containing pans (Note 1) intended for high-temperature and corrosive service (Note 2).
NOTE I-Carbon steel castings for pressure-contain-ing parts are covered by Specification A 216/A 216M, and low-alloy steel castings by Specification A 217 I A217M.
NOTE 2-The committee formulating this specifi-cation has included 24 grades of materials extensively used for the present purpo5e. It is not the intent that this specification should be limited to these grades.
Other compositions will be considered for inclusion by the committee as the need arises. Since these grades possess varying degrees of suitability for high-tempera-ture and corrosion-resistant service, it is the reponsibil-ity of the purchaser to determine which grade shall be furnished, due consideration being given to the require-ments of the applicable construction codes.
1.2 Twenty-four grades of austenitic steel castings are incbded in this specification. Selec-tion will depend on design and service condi-tions, mechanical properties, and the high-tem-perature and corrosion-resistant characteristics.
1.3 The values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. Com-bining values from the two systems may result in nonconformance with the specification.
- 2. Referenced Documents 2.1 ASTM Standards:

- 3. General Conditions for Delivery 3.1 Material furnished to this specification shall conform to the applicable requirements of Specification A 703/ A 703M, including the sup-plementary requirements that are indicated on the purchaser's order.
3.2 The post weld heat treatment require-ments of Supplementary Requirement S 11 may be specified when austenitic castings other than HK, HT, or CT15C are to be subjected to severe corrosive service..
- 4. Ordering Information 4.1 The inquiry and order shall include or indicate the following:
4.1.1 A description of the casting by pattern number or drawing. Dimensional tole~nces shall be included on the casting drawing.
4.1.2 Grade of steel.
4.1.3 Options in the specification.
4.1.4 Supplementary requirements desired in-cluding the standards of acceptance.
- 5. Process 5.1 The steel shall be made by the electric furnace process with or without separate refining such as argon-oxygen decarburization (AOD).
SA-351/SA-351M 1989 SECTION II
- 6. Heat Treatment 6.1 All castings shall receive a heat"treatment proper to their design and chemical composition, except the HK, HT, and CT15C grades which
- shall be fumislt~ in.the ~~
'<;o~dition.
6.2 Grade CD-4MCu shall be heated to l 900°F [I 040°C] minim um for sufficient time to heat casting uniformly to temperature and then quenched in water or rapidly cooled by other means so as to develop acceptable mechanical properties and corrosion resistance.
6.3 The austenitic gcides,-excepfGrades -HK HT, and CTl5C shalfbe solution-treaied by th; manuf~ctµ~r.
- 7. Chemical Compositjon 7.1 The steel shall conform to the require-ments as to chemical composition prescribed in Table I.
- 8. Tensile Properties 8.1 Steel used for the castings shall conform to the requirements as to tensile properties pre-scribed in Tabie 2.
- 9. Quality 9.1 The surface of the casting shall be exam-ined visually and shall be free of adhering ~nci.
scale, cracks, and hot tears. Other surface discon~
ti~uities shall meet the visual acceptance stand-ards specified in the order. Visual Method SP 55 or other visual standards may be used to define acceptable surface discontinuities and finish. Un-acceptable visual surface discontinuities shall be 412 removed and their remo*:al verified by visual examination of the resultant cavities.
9.2 When additional inspection is desired, Supplementary Requirements S5, S6, and SIO may be ordered.
9.3 The castings shall not be peened, plugged, or impregnated to stop leaks.
- 10. Repair by Welding 10.1 Rep8irs shall be. made. using proce-dures and welders qualified under Section IX of the ASME Boiler and Pressure Vessel Code.
10.2 Weld repairs shall be inspected to the same quality standards that are used to inspect the castings. When castings *are produced with Supplementary Requfrement S5 specified, weld repairs on castings that have leaked on hydro-static test, or on castings in which the depth of any cavity prepared for repair welding exceeds 20 % of the wall thickness or 1 in. [25 mm],
whichever is smaller, or on castings in which any cavity prepared for welding is greater than ap-proximately 10 in.2 [65 cm2), shall be radio-graphed to the same standards that are used to inspect the castings. When ca~tings are produced with Supplementary Requirement S6 specified, weld repairs shall be *inspected by liquid pene-trant examination to the same standards that are used to inspect the castings.
NOTE 3-When austenitic steel castings are to be used in services where they will be subject to stress corrosion, the purchaser should so indicate in his order
- and such castings should be solution-heat treated fol-lowing all weld repairs.

llPTCS ll~LLOT OF 8PVC IT£M$
BP'VC ME£TINO OF.5J6/9ot Assurance of Mechanical Requirements, dclctedi para. 10, Visual Inspection, revised; para. 11, Inspection, revised; para. 12, Rejection & Rehearing, rcvisedi para. 15, Product Marking, revised; new para. 17, Keywords, added: ASTM F788 added in para. 2, Referenced Documents; new para. 8, Workmanship, added to reference F788.
This ASTM version includes revisions to ex.elude washers from the requirement that all components be coated by the same process unless otherwise specified on the material order. Approval of these revisions for ASME use drew a negative at the Subgroup level because they required only threaded components (bolts and nuts) to be coated by the same coating process. The previous edition of the spec
... required all mating fasteners (including washers) to be so coated. The relaxation of specification requirements could allow for use of inferior coatings on washers.
Excluding washers from utilization of the snme coating process could result in premature washer degradation resulting from corrosion a..o.d thus loss or rast"ner component clamping force. Thus., 1he ASMr; versions are being adopted without this revision to address this concern.
