All types stainless steel rebar we offer conform to the ASTM A955 standard. This standard covers deformed or plain stainless steel bars for reinforcement in concrete construction where corrosion resistance or controlled magnetic permeability are required.
GRADE 2205 DUPLEX UNS# S31803
This alloy has a microstructure of austenite and ferrite (duplex) due to its chemical balance. The addition of nitrogen provides strength levels close to 80% higher than 304 with superior corrosion properties. The alloy chromium and moly content provides superior pitting and crevice corrosion properties and excellent stress corrosion cracking resistance.
GRADE 316 LN UNS# S31653
This alloy has a lower chromium content, higher nickel than 304, and a 2% moly addition. The latter enhances the corrosion resistance found in harsh environments, especially halogens (chlorides). It offers superior resistance to pitting or crevice corrosion failures typical to high salt of coastal areas. The alloy is austenitic providing excellent formability, weldability, and cryogenic ductility. In addition, this grade has higher creep strength; higher stress ruptures strength and improved tensile strength as compared to 304 type alloys.
EnduraMet™ 32Stainless XM-28 UNS# S24100
N32 is a high-manganese, low-nickel, nitrogen strengthened austenitic stainless steel. By means of solid solution strengthening, the nitrogen provides significantly higher yield and tensile strength as annealed without adversely affecting ductility, corrosion resistance or non-magnetic properties. In the hot rolled unannealed condition, yield strengths of 75 ksi (518 MPa) or higher can be achieved for bar diameters up to 2 in. (50.8 mm). EnduraMet 32 stainless may be considered for rebar in bridge decks, barrier and retaining walls, anchoring systems, chemical plant infrastructure, coastal piers and wharves, bridge parapets, sidewalks and bridge pilings. Because of its low magnetic permeability, it may also be considered for concrete rebar applications in close proximity to sensitive electronic devices and magnetic resonance medical equipment. The higher strength capability, 75 ksi (518 MPa) minimum yield strength, of EnduraMet 32 is an added economical advantage.
