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 super duplex material is NACE and NORSOK approved and has a PREN (pitting resistance equivalent number - an empirical relationship to predict the pitting resistance of austenitic and duplex stainless steels) of 40. "Super" duplex grades have enhanced pitting and crevice corrosion resistance compared with the ordinary austenitic or duplex types. This is due to the further additions of chromium, molybdenum, and nitrogen to these grades. It also conforms, or is similar to, EN / DIN (Werkstoff) 4501 / 1.4501 / X2CrNiMoCuWN25.7.4 / UNS 32760 / S32760, UNS - ASTM A276 S32760 / AISI F55 / GOST 12Kh13 / Afnor Z3CND25.06Az. Also 1.4410 / UNS S32550 / UNS S32750 / Z3CNDU25.07Az / SS2328 / X2CrNiMoCuN25.6.3 / SAF 2507 SANMAC / Uranus 52N. 
Super Duplex 1.4501 / 32760 / F55 Stainless steel 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 (25%) and a moderate nickel content (7%). They also have 3 to 4 % Moly./ Molybdenum. At this level, F55 / UNS 32760 / 1.4501 materials, are too low in nickel to produce a fully austenitic structure, thus producing the duplex microstructure (ferrite and austenite). The main advantage of super-duplex F55 / UNS 32760 / 1.4501 stainless steel is the combination of properties given by both the austenitic and ferritic structure (austeno-ferritic). 
Super duplex stainless steels Acier, inoxydable, Rostfreier, Stahl, Acciaio, Inossidabile, Aco, Inoxidável, Acero, Inox, Inoxidables, Rostfrei, Roestvrij to F55 / UNS S32760 / EN / DIN (Werkstoff) 4501 / 1.4501 / X2CrNiMoCuWN25.7.4 / UNS 32760 / UNS - ASTM A276 S32760 / AISI F55 / GOST 12Kh13 / Afnor Z3CND25.06Az have 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 super-duplex grade F55 / UNS S32760 / EN / DIN (Werkstoff) 4501 / 1.4501 / X2CrNiMoCuWN25.7.4 / UNS 32760 / UNS - ASTM A276 S32760 / AISI F55 / GOST 12Kh13 / Afnor Z3CND25.06Az, can be used for heat exchangers, chemical tanks, refineries, shafts (marine, etc) pressure vessel parts, flanges, fittings & pipes for the oil and gas industries and offshore technology, paper industry, compressor parts and seawater desalination plants amongst many other applications. Intoco offer super duplex materials in round bar (rolled / forged) and sheet / plate, complete with the stainless mill certs conforming to EN10204/3.1 & 3.2 if required with certification supplied by Lloyd's Register, etc. ASTM/AISI F51 / UNS 31803 / 1.4462 Duplex stainless steel Acier, inoxydable, Rostfreier, Stahl, Acciaio, Inossidabile, Aco, Inoxidável, Acero, Inox, Inoxidables, Rostfrei, Roestvrij.
