The type 304 grade may be regarded as the archetypal austenitic stainless steel from which the other grades are derived and changes in composition away from that of type 304 result in a change in the identification number and are highlighted in red. Table 1 Typical compositions of some austenitic stainless steel alloys
For example, on 304 series austenitic stainless steel, you should use an ER308 rod (see Figure 1 for additional options and exceptions). Typically, austenitic stainless steel filler rod is available in diameters from 0.035 to 5/32 inch (0.9 to 4.0 mm) and chosen according to the joint design, welding parameters, and application.
Welded large diameter austenitic steel pipe for corrosive or high temperature service. ASTM A731/A731M: Seamless and welded ferritic and martensitic stainless steel pipe. ASTM A790/A790M: Seamless and welded ferritic/austenitic stainless steel pipe. ASTM A450/A450M: General requirements for carbon, ferritic alloy and austenitic alloy steel tubes.
There are two subgroups of austenitic stainless steel. 300 series stainless steels achieve their austenitic structure primarily by a nickel addition while 200 series stainless steels substitute manganese and nitrogen for nickel, though there is still a small nickel content.
The typical stabilised grades of austenitic stainless steel are 321, 316 Ti (containing Ti) and 347 (containing Nb). In the welding of these stabilised grades, it is generally recommended that a stabilised welding consumable be used. As Ti tends to be lost in the arc, Nb is used for stabilised consumables.
Standard Specication for Seamless, Welded, and Heavily Cold Worked Austenitic Stainless Steel Pipes1 This standard is issued under the xed designationA 312/A 312M; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision.
All of the austenitic stainless steels are weldable with most of the welding processes, with the exception of Type 303, which contains high sulphur and Type 303Se, which contains selenium to improve machinability.
Small-scale resistance spot welding (SSRSW) was carried out for austenitic stainless steels. A weld lobe that shows the process window for making sound joints was obtained for type 304 stainless, small size welded austenitic stainless steel

E527 Practice for Numbering Metals and Alloys in the Unified Numbering System (UNS) Other Standard. SAE J1086
The development of nonrusting stainless steels with distinct attributes that include varying degrees of corrosion resistance, strength, and workability has been a tremendous benefit to steel users. This development, however, also has made welding stainless steel more complicated than welding traditional carbon steel.
Typically, austenitic stainless steel filler rods are available in diameters ranging from.035 to 5/32 (.9-to 4.0-millimeters). Whenever possible, it is best to match the filler and base material to help preserve integrity of the welded joint compared to the base material.
Austenitic stainless steel Austenitic stainless steels typically have 16-26% chromium (Cr) and 8-22% nickel (Ni). Type 304, which contains approximately 18%Cr and 10%Ni, is a commonly used alloy for welded fabrications and these alloys can be readily welded using any of the arc welding processes (TIG, MIG, MMA and SA).
In the frame of this project, 3 stainless steel piping butt weld configurations have been studied, for diameters and 2 and wall thickness respectively of 5.56 mm and 8.74 mm. There are two types of junction: pipe to pipe (P2P) and pipe to elbow (P2E).
THE WELDING OF STAINLESS STEELS 4 an excellent metallurgical quality, with a precise control of penetration and weld shape in all positions; sound and pore-free welds very low electrode wear easy apprenticeship The common workpiece thickness range is 0.5 mm to 3.5 / 4.0 mm. The main advantages of this process when
Austenitic Austenite Stainless Steel. This type of stainless steel is dominant in the market. The group includes the very common AISI 304 and AISI 316 steel, but also the higher alloyed AISI 310S and ASTM N08904. Austenitic steel are characterised by their high content of austenite-formers, especially nickel.
Welding process of 316L stainless steel pipe. The flow rate is 5-14l/min, and the positive argon flow rate is 1213l/min. The seam thickness should be as thin as possible at the bottom of the bottom welding, and it should be in good shape with the root, and the arc should be formed in a gentle slope.
Many of our customers rely on 300 series stainless steel, due to its ease of forming and comparatively low cost. stainless steel tubing coil Relative to other alloys, tubing can be welded and drawn to size efficiently in this series of stainless steel.

ASTM A632 - 04 Standard Specification for Seamless and Welded Austenitic Stainless Steel Tubing (Small-Diameter) for General Service. The specification covers grades of stainless steel tubing for general corrosion-resisting and low or high-temperature service. The tubes shall be cold finished and shall be made by the seamless or welded process.
Austenitic stainless steel A commonly used alloy for welded fabrications is Type 304 which contains approximately 18%Cr and 10%Ni. These alloys can be readily welded using any of the arc welding processes (TIG, MIG, MMA and SA).

Austenitic welds present major inspection problems due to their large grain structure. Radiography does not work well, so ultrasonics is the main choice for inspecting austenitic welds, LNG tank welds, cladding and centrifugally-cast stainless steel pipe. For ultrasonics, the large austenitic grains cause beam skewing, splitting and attenuation.
However, not all stainless steels are easily welded and it can be argued that some stainless steels grades are not weldable at all. So to help, this article will highlight some of the best grades for welding stainless steel. Austenitic Stainless Steels. Austenitic stainless steels can be welded together using many different welding processes.
