02513.00 1112 Section 02513 - Stainless Steel Reinforcement Description
02513.00 Scope - This Section includes the requirements for stainless steel reinforcement bars,
mechanical splices, chairs and supports, inserts, dowels, and tie wire. Materials
02513.10 Deformed Bar Reinforcement - Furnish deformed bar reinforcement m eeting the
requirements of ASTM A955 except for Section 6, C hemical Composition and Section 15, Finish. Acceptable alloys are listed by Uniform Numbering System for Metals and Alloys ( UNS) designation in Table 02513 -1. Finish the surface according to Table 02513- 1 and the requirements of ASTM A380. Table 02513-1 Stainless Steel Alloys for Reinforcing Bars and Dowels UNS Designation S31653 S31803 S20910 S24100 S32304 AISI Type 316LN 2205 XM-19 XM-28 2304 Common or Trade Name Type 316 Low Carbon Nitrogen Added Type 2205 Duplex Nitronic 50 Nitronic 32 Enduramet 32 18-Cr-2Ni-12Mn Type 2304 Duplex SAF 2304 Fe-23Cr -4Ni-0.1N Required Condition As rolled As rolled As rolled As rolled As rolled Required Finish Descaled and white pickled Descaled and white pickled Descaled and white pickled Descaled and white pickled Descaled and white pickled Grade 60 75 60 75 60 75 60 75 60 75 Minimum Tensile Strength (ksi) 90 95 90 95 90 95 90 95 90 95 Minimum Yield Strength (ksi) 60 75 60 75 60 75 60 75 60 75 Minimum Elongation in 2 inches (%) 25 20 25 20 25 20 25 20 25 20
02513.20 Mechanical Splices - Mechanical splices for reinforcing bars are systems which connect
the bars without raisin g their temperature above 1,300 °F. Furnish mechanical splices which develop at least 90 percent of the specified minimum ultimate strength of the reinforcing bars in compression and in tension. Where bars of different sizes or strengths are connected, match the strength of the smaller or weaker bar. Do not allow the spliced reinforcing bars to slip more than 0.040 inch, measured between gauge points clear of the splice sleeve, when the reinforcing bars are loaded in tension to 67 percent of the specified minimum yield strength of the reinforcing bar. 02513.70 Fabricate the splice sleeve and connection hardware from an alloy listed in Table 02513-1. Finish the s urface according to Table 02513-1 and the requirements of ASTM A380.
02513.30 Chairs and Supports - Furnish chairs and continuous supports fabricated from an alloy
listed in Table 02513-1. Finish the surfa ce according to Table 02513-1 and the requirements of ASTM A380.
02513.35 Concrete Inserts - Furnish concrete inserts fabricated from an alloy listed in Table
02513- 1. Finish the surface according to Table 02513-1 and the requirements of ASTM A380. Furnish concrete inserts with closed-back ferrule threaded to receive UNC threaded bolts or rods of the size shown. Provide concrete inserts with the following minimum lengths and safe working loads: Bolt or Rod Insert Safe Working Load Diameter Length in Shear or Tension (Inches) (Inches) (Pounds) 3/4 4 1/2 4,000 1 5 1/2 6,000 1 1/4 7 1/2 10,000 1 1/2 9 1/2 16,000
02513.50 Dowels - Furnish dowels meeting the requirements of ASTM A955 except for Section 6,
Chemical Composition and Section 15, Finish. Acceptable alloys are listed by Uniform Numbering System for Metals and Alloys (UNS) designation in Table 02513-1. Finish the surface according to Table 02513-1 and the requirements of ASTM A380.
02513.60 Tie Wire - Furnish 16 gauge tie wire meeting the requirements of ASTM A555 and
fabricated from an alloy listed in Table 02513- 1, in dead soft annealed condition and passivated according to ASTM A380.
02513.70 Acceptance - Stainless steel reinforcement will be accepted according to 00165.35 and
this Section.
