Apr 10, 2013 The only difference in SA 266 Gr. 2& SA 266 Gr. 4 is, content of Manganese is approximately double ( ) in SA 266 Gr. 4 than SA 266 Gr. 2 ( ). These materials are widely used for body flanges, tubesheets, backing devices of heat exchangers and vessels. sa266 grade 2 ASTM A266 Grade 1 Carbon Steel. ASTM A266 grade 1 is a type of ASTM A266 carbon steel. Cited properties are appropriate for the normalized condition. It has the lowest strength and highest ductility compared to the other variants of ASTM A266 carbon steel.

Jan 08, 2011 Raghuram Bathula SA266 has 4 grades, only grade 3 has 0. 35 C and rest are with 0. 3 C, it is generally used for pressure vessels mostly for high wall thickness, self reinforced or large dai forgings, tube sheets etc. , since SA105 has limitation for weight (4540 Kg max) other wise Grade 2 and 4 are of same UTS values of SA105 ASME SA 266 sa266 Grade 4 gr 4 Gr. 4 Gr. 4 Gr4 forged forging steel discs disks tubesheets tube sheets tube plates blocks round bars hollow bars ASTM A266 Grade 4 Gr4 cl4 forged forging rings seamless rolled rings forged forging Sleeves Bushes Bushing Pipes Piping tube tubings barrels Casing Cases Shells cylinders hubs housings SA266 Class 4 Cl. 4 GR II Cl4 Cl. 4 forged forging steel Girth Please send us the drawing of ASME SA 266 sa266 Grade 4 gr 4 Gr. 4 Gr. 4 Gr4 forged forging steel discs disks tubesheets tube sheets tube plates blocks round bars hollow bars ASTM A266 Grade 2 Gr2 cl2 forged forging rings seamless rolled rings forged forging Sleeves Bushes Bushing Pipes Piping tube tubings barrels Casing Cases Shells cylinders sa266 grade 2 A266 A266M18 Standard Specification for Carbon Steel Forgings for Pressure Vessel Components pressure vessels superheater tubes boiler tubes steel forgings Products and Services Standards& Publications Standards Products ASME SA 266 sa266 SA266 Grade 2 gr 2 Gr. 2 Gr. 2 Gr2 Forged Forging Steel Tube Sheets Discs Disks Tubesheets tube plates ASTM A266 Grade 2 Gr2 cl2 Class 2 Cl. 2 GR II Cl2 Cl. 2 FRONT REAR Fixed STATIONARY Floating Cladding Clad Cladded Welding Welded Feb 04, 2002 Of course SA266 Cl. 2 is allowed under Section VIII Div. 1. The two materials are quite equivalent in my opinion: only minor differences in the specification (heat treatment policy for instance). I think the choice is a matter of taste, or, better said, of continuity at client's organisation. ASTM A266 Grade 2 Carbon Steel. ASTM A266 grade 2 is a type of ASTM A266 carbon steel. Cited properties are appropriate for the normalized condition. The graph bars on the material properties cards below compare ASTM A266 grade 2 to: wrought carbon or nonalloy steels (top), all iron alloys (middle), and the entire database (bottom). A full bar
