ASTM A312 TP316L PIPE

ASTM A312 is Stainless Steel Pipe Specification Standard Specification for Seamless, Welded, and Heavily Cold Worked Austenitic Stainless Steel Pipes. ASTM A312 pipe is common use stainless pipe for industries. 

SAE 316L grade stainless steel, sometimes referred to as A4 stainless steel or marine grade stainless steel, is the second most common austenitic stainless steel after 304/A2 stainless steel.  Since 316L contains less carbon than 316, it has better intergranular corrosion resistance, 316L is the superior choice for high corrosion and high temperature applications.

Type 316L is the low carbon version of 316 stainless. With the addition of molybdenum, the steel is popular for use in severe corrosion environments due to the materials immunity from boundary carbide precipitation (sensitisation). The material is widely used in heavy gauge welded components and weld annealing is only required where the material is for use in high stress environments. 316L has an extensive variety of uses especially in marine applications due to the materials high corrosion resistance.

Benefits of using Type 316L Stainless Steel Low carbon content eliminates carbon precipitation in the welding process Can be used in severe corrosive environments Improved anti-corrosion scope due to added Molybdenum Weld annealing only required in high stress applications Very similar to Grade 316 in chemical composition and mechanical properties 316 & 316L steel plate and pipes have common properties and are often stocked with Dual Certification, where it is determined that both have properties and composition which comply with both steel types. Type 316H is excluded from this scenario by virtue of the fact that unlike 316 & 316L, 316H is engineered to work in elevated working temperatures.
