Duplex and Super Duplex Cast Stainless Steels 双相钢和超级双相钢
SteelsCast samples containing a series of 'steps' of different thickness and made of two typical superduplex stainless steel grades were manufactured. A numerical simulation code has been employed for the evaluation of fluidodynamics and thermal fields induced during casting as well as for the ...
Super_Duplex_Stainless_Steel_Article Duplex Stainless Steel History:Duplex stainless steels are a family of grades combining good corrosion resistance with high strength and ease of fabrication. Duplex stainless steels,meaning those with a mixed microstructure of about equal proportions of austenite and ...
FORMING AND STRESS RELIEVING OF WELDED SUPERDUPLEXSuperduplex stainless steelThe value of superduplex stainless steels is demonstrated by a similar corrosion resistance compared with superaustenitic grades and the higher tensile properties of carbon steels. It makes these stainless steels a cost effective...
Best Stainless provides Super Duplex 2507 stainless steel, a 50/50 mixture of austenite and ferrite, is stronger than either a pure austenitic or ferric alloy. Call us!
However, over the last 10 years, themajority of the seawater capable stainless steel literature has been focused onsuper-austenitic (6% and 7% Mo alloys) and super-duplex alloys. While theperformance of these alloys has been very good, today's material raw material prices have driven the ...
Although mechanical properties are not the primary reason for selecting superaustenitics, advantages can be gained from the fact that they have yield strengths up to twice that of the standard austenitic grades. Compared to superduplex stainless steels, superaustenitics have the advantages of a ...
Corrosion Study of Super Ferritic Stainless Steel UNS S44660 (26Cr-3Ni-3Mo) and Several Other Stainless Steel Grades (UNS S31603, S32101, and S32205) in Caustic Solution Containing Sodium Sul- fide[J].Metallurgical and Materials Transactions A, 2013, 44(11): 5039--5053....
