SS is a material that has very good ductile properties, which is why most SS Pipes Manufacturer find it relatively easy to shape them into various forms such as ss square pipes, round, rectangle etc.

Stainless Steel Pipe

A benefit of using austenitic ss grades is that one alloy grade is very different from the other and while they may have similarities or some overlaps in their properties, they can be used in different applications. To illustrate, let us take into consideration grade 304L, grade 304H and grade 304. Although the SS Seamless Pipes produced from grade 304 has the same chemistry as the other two grades, the modification with regards to the content of carbon is what makes them dissimilar.


Grade 304H is a high carbon variety of grade 304, and pipes produced from grade 304H ss pipes asme sa312 can be used for high temperature applications. On the other hand, grade 304L schedule 10 ss pipes is a low carbon version and is specifically designed to be used for welding related operations. This is because a low content of carbon in 304L ss round pipes does not promote intergranular corrosion, while, the higher content of carbon in 304H ASTM A312 Seamless Pipes is prone to decay by sensitization. The stabilization of 304L ss welded pipe with nitrogen makes it almost as tough as its more conventional predecessor. Click here to learn more about the schedule 40 ss pipes dimensions here.

What is ASTM A312 stainless steel pipe?

As typical of the various existing ASTM specifications, the ASTM A312 takes into consideration the requirements pertaining to the chemistry, tensile properties as well as testing parameters. In this case, there are different austenitic stainless steel grade pipes that are produced under this specification. Further, it also covers the construction techniques used in their manufacture i.e. welded (cold worked welded or straight seam welded) as well as seamless constructed pipes.

Designed with the intended of being used for high temperature applications, the ASTM A 312 pipes can also be used in applications that require resistance to general corrosion. With regards to the conformance to the chemistry requirements of these austenitic stainless steel grades, the common elements added to these alloys include manganese, nickel, aluminium, phosphorus, sulfur, silicon, molybdenum, titanium, carbon, chromium, copper, cerium, columbium, tantalum, nitrogen, vanadium and boron. All pipes produced under the are to be furnished in the heat-treated condition.

Performance of this heat treatment procedures is to be carried out in accordance with the required temperature in addition to the cooling and testing requirements as well. Another aspect the ASTM A312 specification locks into is the tensile properties of the material being used to produce the pipe. Hence it is expected that these pipes conform to the prescribed requirements such as the tensile strength and yield strength. With regards to the testing parameters, mechanical tests are conducted on the pipes such as transverse or longitudinal tension test along with a flattening test. Furthermore, each pipe is to be subjected to not only a nondestructive electric test or a hydrostatic test but also a grain size determination test, as well as weld decay tests.
