The 316 stainless steel pipe has become an indispensable material for the industrial sector. This alloy of iron and chrome is recognized for its high resistance to corrosion, as well as its durability. 316 stainless steel tubing can be produced in both seamless and welded tubes to meet specific customer needs.

SMO 254 Pipes can withstand high mechanical stress and Alloy 254 SMO Pipe high pressure work in high temperatures and corrosive environments.

316L 1.4401 S31603 Stainless Steel Pipe is a highly versatile and durable pipe option commonly used in a wide range of industrial and commercial applications. This SS UNS S31603 pipe is made from high quality 316L stainless steel with excellent resistance to corrosion, oxidation and staining, making it ideal for harsh environments or high stress applications.

UNS N08367 also commonly referred to as alloy AL6XN is a low carbon, high purity, nitrogen-bearing “super-austenitic” nickel-molybdenum alloy with excellent resistance to chloride pitting and crevice corrosion.

ASTM A312 TP316 is a standard specification for seamless, straight-seam welded, and heavily cold worked welded austenitic stainless steel pipes used in high-temperature and general corrosive service applications. The 316 Seamless Industrial Steel Pipe is made from a combination of chromium, nickel, and molybdenum, which gives SS 316 Seamless Tube excellent resistance to corrosion and rust.

AL6XN is a superaustenitic stainless steel with outstanding resistance to chloride pitting, crevice corrosion and stress corrosion cracking. AL6XN is a 6 moly alloy that was developed for and is used in highly aggressive environments. It has high nickel (24%), molybdenum (6.3%), nitrogen and chromium contents that give it excellent resistance to chloride stress corrosion cracking, chloride pitting, and exceptional general corrosion resistance. AL6XN is primarily used for its improved pitting and crevice corrosion resistance in chlorides. It is a formable and weldable stainless steel.

304L is preferred. And it lacks a minimum carbon content, which is not ideal for high temperature applications where optimum strength is required, so 304H is the first choice. Thus, 304 is generally limited to rods or sheets that are to be machined into components that do not require welding, or sheets formed in articles, such as kitchen sinks or cookware, which are also not welded.

316L is a better choice as 316 is more susceptible to weld corrosion than 316L (corrosion within the weld). However, 316 can be annealed to resist weld decay. 316L is also a premium stainless steel for high temperature, high corrosion applications, which is why it is so popular in architectural and marine projects.

It also has a high resistance to pitting in chloride solutions, a high resistance to both crevice and stress corrosion cracking. Alloy 904L performs better than other austenitic stainless steels due to the higher alloying of nickel and molybdenum.

Cold working the ASME SA312 grade 304 pipe is usually performed in order to permanently change the crystalline structure of the alloy by application of mechanical strength. This in turn is what causes an increase in the tensile strength properties of the SS 304 seamless pipe, that too without the use of heat.

The increased nickel content and the inclusion of molybdenum makes grade 316 stainless steel a bit costlier than grade 304 per ounce of material. But where grade 316 stainless proves superior is its increased corrosion resistance¡ªparticularly against chlorides and chlorinated solutions. This makes grade 316 stainless particularly desirable for applications where exposure to salt or other powerful corrosives is an issue.

Bright Annealed (BA) is produced by heat-treating (annealing) steel with a controlled atmosphere furnace. After heat-treatment, the steel has a reflective, mirror-like appearance, but may also have some imperfections and cloudiness. BA stainless steel can be buffed to attain a more reflective finish, and is often specified for applications where a highly reflective surface is desired.

It is rolled into strip steel after process treatment. Generally, the strip steel is unpacked, flattened, crimped, and welded to form a round tube, then the round tube is rolled into a square tube and then cut to the required length. Usually 50 pieces per pack.
Square pipes are divided into seamless and welded seams. Seamless square pipes are formed by extruding seamless round pipes.

SUS316L pipe has excellent forming and welding characteristics. It is easily braked or rolled into various parts for use in industry, construction and transportation.

Often in many product forms, the grain size and carbon content can meet both the 310S and 310H requirements. 310 is often used at cryogenic temperatures, with excellent toughness to -450¡ãF, and low magnetic permeability. 310 has a machinability rating of 42% relative to AISI B1112 steel. When using high speed steel tooling, this equates to about 70 surface feet per minute.
