Detailed Description 

Intoco specialise in no-compromise manufacture using state-of-the-art CNC equipment, and the finest steels available. We are also a very large stockholder of hot work tool steels, stainless steels (440c / 1.4125 / 4125 / X105CrMo17), duplex stainless steel (ASTM A182 A276 / AISI / F51 EN / DIN (Werkstoff) 1.4462 and X2CrNiMoN22-5-3, UNS 31803 / S31803 / S32205, Afnor Z2CND22-5Az, BS318S13, SS2377, BS332C15, EN (10283) 1.4770, branded steel SAF2205, URANUS 45N, FALC223) and super duplex stainless steel conforming to ASTM / AISI / F55 in round bar and plate / sheet form. 
Our duplex material is NACE and NORSOK approved. It also conforms, or is similar to EN / DIN (Werkstoff) 1.4462 and X2CrNiMoN22-5-3, UNS 31803, Afnor Z2CND22-5Az BS318S13, SS2377, BS332C15, EN (10283) 1.4770 and branded steel SAF2205, URANUS 45N and FALC223. Duplex 1.4462 / 31803 / F51 Acier, inoxydable, Rostfreier, Stahl, Acciaio, Inossidabile, Aco, Inoxidável, Acero, Inox, Inoxidables, Rostfrei, Roestvrij materials get their name, duplex, because they contain both ferritic and austenitic microstructure. They have a high chrome / chromium content (22%) and a moderate nickel content (5.5%). They also have 3% Moly./Molybdenum. At this level, F51 / UNS 31803 / 1.4462 materials, are too low in nickel to produce a fully austenitic structure, thus producing the duplex microstructure (ferrite and austenite). The main advantage of Duplex F51 / 1.4462 / UNS 31803 stainless steel is the combination of properties given by both the austenitic and ferritic structure (austeno-ferritic). 
Duplex stainless steels Acier, inoxydable, Rostfreier, Stahl, Acciaio, Inossidabile, Aco, Inoxidável, Acero, Inox, Inoxidables, Rostfrei, Roestvrij to F51 / UNS 31803 / Afnor Z2CND22-5Az / X2CrNiMoN22-5-3 / B.S. 318S13 / SAF2205 / 1.4462 / Uranus 45N / FALC223 / SS2377 / 1.4470 / 329LNhave excellent corrosion resistance, increased resistance to chloride attack, good resistance to stress corrosion cracking, tensile and yield strength higher then conventional austenitic or ferritic grades of stainless steel, good weldability and good formability. 
Stainless steel Duplex grade 2205, F51, UNS 31803, 1.4462, AFNOR Z2CND22-5Az, BS318S13, SAF2205, X2CrNiMoN22-5-3, 329LN, URANUS 45N, FALC223, SS2377, BS332C15, 1.4470. Can be used for heat exchangers, chemical tanks, refineries, shafts (marine, etc) pressure vessel parts, flanges and pipes for the oil and gas industries, paper industry, compressor parts and seawater desalination plants. Intoco offer Duplex material in round bar (rolled / forged) complete with the stainless mill certs conforming to ASTM/AISI F51 / UNS 31803 / 1.4462 Duplex stainless steel Acier, inoxydable, Rostfreier, Stahl, Acciaio, Inossidabile, Aco, Inoxidável, Acero, Inox, Inoxidables, Rostfrei, Roestvrij.
