In addition to the time and labor savings, long bars with fewer connections also save weight and space without any loss of strength. This has the effect of extending the service life of structures to 100+ years without major repair due to the unique chemistry containing a mix of over 30% of alloys formulated to resist chloride corrosion. The rebar had to have superior corrosion resistance to withstand the attack of salt-laden air and fog from the Pacific Ocean, and the chloride-containing moisture that used to initiate corrosion underneath the structures. Although ASTM designation A 276 lists a good number of stainless alloys that are suitable for use in concrete reinforcement, any one of four major stainless steels can be considered for most applications. Table 3 sets a few of the bridge projects using stainless steel rebar: In regions where salt is used to de-ice the roads in winter, vehicles bring the salt into parking garages on their tyres and bodywork.
As they have provided virtually trouble-free service, the exact construction dates and details of several of these structures have now become difficult to determine. ODOT required a strength level of 75 ksi (520 MPa). Like the previous two alloys, stainless Type 304LN is also non-magnetic. Types of Stainless Steel Reinforcing Bars, 2. to 90,000 lbs.

Given its exceptional corrosion resistance, there are significant benefits that flow back to the Owner by specifying stainless steel : More information on the properties, benefits, availability and features relating to stainless steel rebar can be found in the section Why Use Stainless. Of paramount concern here is the need for high strength to preserve the structural integrity of any bridge subject to a seismic disturbance, and the safety of motorists using it. The seismic retrofit of bridges, it should be noted, is one of six major categories earmarked for funding by the Federal Highway Administration (FHWA). For some bridges, the extra cost of not using stainless steel rebar has been found to add between 1% and 3% to the total project cost. Background: Progreso Pier, built with stainless steel reinforcement in 1941. Selective substitution with stainless steel rebar would have greatly reduced future maintenance costs and would have extended the service life of the bridge to 75-100 years.

Stainless Type 316LN is a nitrogen-strengthened version of stainlessType 316L. That is an amount likely to be $25 million, or at least twice the cost of bridge construction today. Manufacturer of metal powders. A simple substitution of carbon steel rebar with stainless steel will mean: Studies have shown that connecting stainless steel rebar to carbon steel rebar in concrete does not create an active galvanic couple and thus does not accelerate corrosion of the carbon steel rebar. What are the different types of handrails used in bridges? The selective use of stainless steel rebar will greatly reduce maintenance costs and postpone the need for any major rehabilitation or replacement of the structure.

Capabilities include milling, horizontal and vertical machining, hole drilling and saw cutting. Chloride attack of steel rebar due to man-induced sources such as road salt or chemical processing, or natural causes such as marine spray, results in a severe deterioration or spalling of concrete structures. Often, the repairs are needed because the carbon steel rebar - whether epoxy-coated or not - corrodes, causing the concrete to crack. Designers or materials specifiers who want a stainless steel with low permeability should specify that the material be checked in accordance with ASTM test method A 342. Possible applications for corrosion resistant stainless rebar could include a host of marine structures such as bridge decks, sidewalks, ramps, parapets, pilings, barriers, retaining walls, anchoring systems, parking garages, sea walls, columns, piers, jetties and moorings.
