SECTION 033000 - CAST-IN-PLACE CONCRETE

Sludge Treatment Project Engineered Container Retrieval and Transfer System January 2012
the base material (e.g., stainless steel L-grade base metal shall be welded with L-grade filler metal).
Lot tests (charpy V-Notch and Bend) temperatures shall be at or below the design metal temperature.
B. Stainless-steel welding material shall meet the requirements of AWS D1.6/D1.6M, stainless steel
E308/ER308 or E309/ER309 electrodes
C. Austenitic stainless steel (A-No. 8) welding materials for pressure boundary and load bearing
welds shall contain a minimum delta ferrite content of five percent. Compliance with the ferrite
requirements may be based upon the certified chemical analysis and the ferrite gage complying
with AWS A4.2. Alternately, for Shield Metal Arc Welding and solid wire filler material manufactured
in the USA, CMTR is required for all filler materials.
D. Carbon steel-welding material shall meet the requirements of AWS D1.1/D1.1M, Carbon Steel
E70XX electrodes
E. For dissimilar welds, such as carbon or low alloy steels to austenitic stainless steels, and different
grades of stainless steel, such as 304L pipe to 316L valve the welding procedure application list
shall specify the filler material type.
F. For all filler metal, a typical test report in accordance with ASME Boiler and Pressure Vessel Section
II, Part C, is required.
G. The storage, baking, and drying of all welding consumables (i.e., covered electrodes, flux cored
electrodes, and fluxes) shall be as recommended by the manufacturer. Segregation of carbon steel,
low alloys, and alloy consumables is required during storage, baking, holding, and handling (including
portable ovens).
2.11 FASTENERS
A. Graded fasteners shall be carefully controlled as defined in the Section 014000, Quality Assurance
and Control.
B. Fasteners shall be inspected to verify compliance with the requirements listed on the design
drawings or procurement specifications.
C. Stainless-steel bolts, cap screws, and studs shall be per ASTM A193/A 193M, Grade B8 (Class 2),
and nuts shall be heavy hex nuts per ASTM A194/A 194M, Grade 8, 8S (Nitrinic 60) or 8SA
(Nitronic 60). Washers for stainless steel bolting shall be as recommended in ASME PCC-1-
2010, Appendix M. Bolts, cap screws, studs and nuts shall be grade marked.
D. Carbon-steel bolting shall be:
1. Bolts General Applications: ASTM A 307, Grade A or B.
2. Nuts General Applications: ASTM A 563, Grade A, heavy hex.
3. Bolts Structural Connections: ASTM A 325.
