We are offering alloy steel valves 2205. seamless pipe 12" - 8" weld pipe 12" - 12" butt-weld fittings 12" - 12" flanges 12" - 8" bar 1" - 8"specifications astm a790, a815, a182 asme sa790, sa815, sa182 description avesta sheffield 2205 is a ferritic-austenitic stainless steel which combines many of the beneficial properties of both ferritic and austenitic steels. As a result of high chromium and molybdenum contents, the steel has very good pitting and uniform corrosion resistance to stress corrosion cracking as well as high mechanical strength. 2205 has good weldability and can be welded using most of the welding techniques for stainless steels. Due to the balanced composition, when welded correctly, the heat affected zone contains sufficient austenite to avoid the risk of localized corrosion. The chemical composition of 2205 is balanced to give a microstructure containing roughly equal amounts of ferrite and austenite. design features • high strength. • low thermal expansion and higher heat conductivity than austenitic steels. • high resistance to stress corrosion cracking, corrosion fatigue and erosion. • high uniform corrosion resistance. • high pitting and crevice corrosion resistance. • good sulfide stress corrosion cracking resistance.

We are offering alloy steel valve 904l. availability seamless pipe 12" w specifications astm b677, b366 asme sb677, sb366 description 904l is a high-alloy austenitic stainless steel with low carbon content. The grade is intended for use under severe corrosive conditions. It has been application proved over many years and was originally developed to resist corrosion in dilute sulfuric acid. It is standardized and approved for pressure vessel use in several countries. Structurally, 904l is fully austenitic and is less sensitive to precipitation ferrite and sigma phases than conventional austenitic grades with high molybdenum content. Characteristically, due to the combination of relatively high contents of chromium, nickel, molybdenum and copper 904l has good resistance to general corrosion, particularly in sulfuric and phosphoric conditions. design features good resistance to pitting and crevice corrosion. very good resistance to stress corrosion cracking. good resistance to intergranular corrosion. good formability and weldability. maximum service temperatures of 450 deg.c. (824 deg.f).

We are offering incoloy valve 825. Availability seamless pipe 12" - 8" welded pipe 8" - 12" butt-weld fittings 12" - 8" flanges 12" - 8" bar 1" - 6"specifications astm b443, 8705, 8366, b425, b564 asme sb443, sb705, sb366, sb925, sb564 description alloy 825 is a nickel-iron-chromium alloy with additions of molybdenum, copper and titanium. The alloys chemical composition provides exceptional resistance to many corrosive environments. The nickel content is sufficient for resistance to chloride-ion stress corrosion cracking. The nickel, combined with molybdenium and copper, also gives outstanding resistance to reducing environments such as those containing sulfuric and phosphoric acid. The molybdenium also aids resistance to pitting and crevice corrosion. The alloys chromium content confers resistance to a variety of oxidizing substances such as nitric acid, nitrates and oxidizing salts. The titanium addition, with appropriate heat treatment, will stabilize the alloy against sensitization to intergranular corrosion. design features good resistance to stress corrosion cracking. Satisfactory resistance to pitting and crevice corrosion. Good resistance to oxidising and non-oxidising hot acids. Good mechanical properties at both room and elevated temperatures up to approximately 550 deg.c (1020 deg. F). Permission for pressure-vessel use at wall temperature up to 425 deg. C (800 deg. F).
