ASTM A Pipe Fittings, ASTM A Butt weld Fittings, ASTM AM Duplex Pipe Fittings
Forging or shaping operations are performed by hammering, pressing, piercing, extruding, upsetting, rolling, bending, fusion welding, machining or by combination of two or more of these operations. All information is based on our present knowledge and is given in good faith. Chemical and product analyses is performed and is conform to the required chemical composition in carbon, manganese, phosphorus, silicon, sulfur, nickel, chromium, molybdenum, copper, nitrogen.
So, theKSI for them is the same as ASTM standards generally consider yield and tensile stresses to be rounded to the nearest ksi, so yourwould round to ksi and would asttm the criteria in the standard barely. They are not quite as easily welded as the austenitic grades but low thermal expansion in duplex grades reduces distortion and residual stresses after welding. I should have clarified as such. It’s easy to join and it’s free.
Forging or shaping operations shall be performed by hammering, pressing, piercing, extruding, upsetting, rolling, bending, fusion welding, machining or by combination of two or more of these operations. Current News Archive Standard Technically. The result meets the requirement. The materials shall undergo heat treatment and shall follow the required cooling process and tempering temperature.
ASTM A specification stands for stainless steel pipe fittings or buttweld fittings. The Eng-Tips staff will check this out and take appropriate action.

My customer’s engineer is giving me a hard time about this reading on the MTR. The steel shall be melted by electric furnace, vacuum furnace, or electric furnace followed by vacuum or electroslag-consumable remelting.
Download Now White Paper: Duplex stainless steels are in most cases, tougher than ferritic stainless steels. It is informational only and not an official part of the standard; the full text of the standard atm must be referred to for its use and application.
Reasons such as off-topic, duplicates, flames, illegal, vulgar, or students posting their homework. We are the exporter and manufacturer of these pipe fittings which are high quality and provides high mechanical strength, good weldability and good corrosion resistance. These precautions are necessary to avoid cross contamination of stainless steel by easily corroded metals that may discolour the surface of the fabricated product. Please note that the ‘Datasheet Update’ date shown above is no guarantee of accuracy or whether the datasheet is up to date.
Duplex stainless steels have astj weldability.
Where we use a period between whole numbers and decimal places, they use commas. Historical Version s – view previous versions of standard. At low temperatures duplex stainless steels have better ductility than the ferritic and martensitic grades.

The materials shall undergo heat treatment and shall follow the required cooling process and tempering temperature. I have attached Table 4 as a JPG for review. Stainless Steel Welded Pipe Fittingss is generally considered to be wieldable by the common fusion and resistance. The recommended filler material for stainless steel is This combination of properties can mean some compromise when compared with pure austenitic and pure ferritic grades.
Students Click Here Join Us! Fabrication of all stainless steels should be done only with tools dedicated to stainless steel materials. Duplex steels are also magnetic, a property that can be used to easily differentiate them from common austenitic grades of stainless. This abstract is a brief summary of the referenced standard.
