What is the difference between UNS S32750 and S32760?
S32750 (UNS S32750, DIN 1.4410, ASTM F53) was originally developed as SAF2507 in the 1980s by Sandvik. S32760 (UNS S32760, DIN 1.4501, ASTM F55) was originally developed as Zeron 100 by the UK company Mather & Platt in the 1970s. It contains a slightly higher copper and tungsten content compared with S32750.
What material is UNS S32750?
super duplex stainless steel
Material to UNS S32750 is described as a super duplex stainless steel with a microstructure of 50:50 austenite and ferrite.
What is UNS S32550?
UNS S32550. GENERAL PROPERTIES. Super duplex UNS S32550 is a stainless steel grade that offers excellent corrosion resistance in a wide variety of corrosive chemicals including sulphuric, phosphoric and nitric acids.
What is UNS S31803?
UNS S31803 is a duplex grade with a ferritic-austenitic microstructure. The alloy consists of around 40-50% ferrite in the annealed condition. The duplex microstructure has the high strength of the ferritic grades whilst retaining the corrosion resistance of the austenitic grades.
What is duplex and super duplex stainless steel?
Super Duplex stainless steels are based around an alloying addition of 25% chromium, whereas duplex stainless steels are based around an alloying addition of 22% chromium. By increasing the chromium content, the level of pitting corrosion resistance is also increased.
Is UNS S32750 Super duplex?
Super Duplex stainless like S32750, is a mixed microstructure of austenite and ferrite (50/50) which has improved strength over ferritic and austenitic steel grades.
What is s31803 material?
Duplex-grade stainless steel alloys have ferritic/austenitic properties, giving these materials superior strength and excellent resistance to oxidation.
What grade is super duplex stainless steel?
Our duplex steel grades 2507 and 4501 are regarded as super duplex stainless steel grades. They are highly alloyed and have a corrosion resistance comparable to high performance austenitics like 254 SMO®.
What is UNS S32760 material?
Material to UNS S32760 is described as a super duplex stainless steel with a microstructure of 50:50 austenite and ferrite. Good Ductility
What is S32760 super duplex grade?
S32760 super duplex grade has enhanced pitting and crevice corrosion resistance in comparison with the ordinary austenitic or duplex types and is suitable for use in aggressive environments. This is due to the higher additions of chromium, molybdenum and nitrogen.
What is the difference between UNS S32760 and 6% molybdenum?
However, the chemical makeup of both grades requires identical amounts of carbon, chromium, and nickel; making them interchangeable for some applications. UNS S32760 is able to compete strongly with the 6% molybdenum “super austenitic” grades in some applications, as it has fewer amounts of Mo and Ni which drive up the base cost of the material.
