HARTSVILLE, SC, USA – March 26, 2008 - EnduraMet® 32
stainless, a new
grade of high quality, low nickel reinforcing bar (rebar) is now available as a
lower cost alternative to stainless Alloy 2205 and AISI 316LN.
EnduraMet 32 stainless can be considered for bridge decks
and parapets, barrier and retaining walls, anchoring systems, chemical plant
infrastructure, coastal piers and wharves, pilings, dowel bars, welded-wire
mesh and tie wire, and many other applications where excellent corrosion
resistance and superior strength are required.
When imbedded in concrete, the new rebar alloy has corrosion
resistance and strength comparable to that of the well known premium quality
materials. The new product is made by Talley Metals, a subsidiary of
Carpenter Technology Corp., Wyomissing, PA.
With its low magnetic permeability, EnduraMet 32 stainless may
be considered for concrete rebar applications in close proximity to sensitive
electronic devices and magnetic resonance medical equipment. It also can be considered
for the construction of deperming piers where low magnetic permeability is
critical.
EnduraMet 32 stainless is a high-manganese, low-nickel,
nitrogen-strengthened austenitic stainless steel that provides a significantly
higher tensile strength than conventional austenitic stainless steels such as
Type 304 and Type 316 without adversely affecting ductility, corrosion
resistance or magnetic properties. In the hot rolled condition, yield strengths
of 75 ksi (518 MPa) or higher can be achieved for bar diameters up to 2 in.
(50.8 mm).
The new rebar material resists corrosion in concrete,
meeting the 100+ year life requirement in current specifications. In the
15-week corrosion macrocell test in simulated concrete pore solution, EnduraMet
32 stainless had an average corrosion rate less than 0.25 micro-meter/yr. and a
grade 75 strength capability.
EnduraMet 32 stainless rebar is available from Talley in standard rebar diameters
of #3 to #16, in metric sizes of 10mm to 50 mm, and in lengths of 20 ft. to 40 ft.
