ASME B36.19M is the standard specification for stainless steel pipes, which specifies the dimensions, tolerance, and manufacturing requirements for both welded and seamless pipes.

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.

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.

SAE 304 stainless steel is the most common stainless steel. The steel contains both chromium (between 18% and 20%) and nickel (between 8% and 10.5%)[1] metals as the main non-iron constituents. It is an austenitic stainless steel. It is less electrically and thermally conductive than carbon steel. It is magnetic, but less magnetic than steel. It has a higher corrosion resistance than regular steel and is widely used because of the ease in which it is formed into various shapes.[1]

With regards to corrosion resistance, 321 Stainless Steel is equivalent to Grade 304 in the annealed condition and is superior if the application involves service in the 797¡ã to 1652¡ã F range. 321 Stainless Steel combines high strength, resistance to scaling and phase stability with resistance to subsequent aqueous corrosion.
UNS S32100 Reducing Tee is preferred due to its ability to work in high pressure and temperature even at a higher temperature.
Stainless Steel 321 / 321H Pipe Fittings are used in filtration, refrigeration, oil, gas, petrochemical and in offshore oil drilling industries. The material has chromium, nickel, titanium and other elements along with carbon. The 321H has higher carbon than the other versions. There are different types of fittings such as the 321/321H Stainless Steel Buttweld Fittings which are most commonly used but there are also the seamless fittings. The Stainless Steel UNS S32100 Pipe Elbow is a fitting type that is used in high temperature applications to change direction of flow.

Applications and Materials
Normalizing is mainly used for normalizing the structure of carbon steel and low alloy steel after forging, hot rolling or casting. The hardness obtained after normalizing depends on the steel dimensional analysis and the cooling rate used (approximately 100-250 HB).

This material is widely used in large gauge welded components and weld annealing is only required when the material is used in high stress environments. Due to the material’s high corrosion resistance, 316L has a wide range of uses, especially in marine applications.
