ASTM A312 TP316L Seamless Stainless Steel Pipe,SA 312 TP316/TP316L pipes,ASTM A312 TP316L Pipes
We are the professional exporter and supplier of ASTM A312 TP316 Seamless Stainless Steel Pipes, ASME SA312 TP316L Seamless Stainless Steel Pipes
ASTM A 312 TP316 316L Pipe
A312 TP316L pipes are made from TP316L stainless steel, which is a low carbon version of TP316 stainless steel. The composition typically includes chromium, nickel, molybdenum, and small amounts of other alloying elements. This composition provides excellent corrosion resistance and high-temperature strength.
Manufactured in compliance with ASTM A312 standards, Our ASTM A312 TP316L stainless steel pipes meet stringent quality requirements, ensuring consistency and reliability in performance. You can trust our TP316L pipes to deliver the durability and performance your projects demand.
ASTM A312 TP316 and TP316L are designated with UNS S31600 and UNS S31603, respectively. Although more expensive, pipes made of TP316/ TP316L have higher level corrosion resistance than that ofTP304/ TP304L. They can be used for a diversified range of corrosive chemical process piping which involves inks, rayon, photographic chemicals, paper, textiles, bleaches, and rubber.
A312 TP316L is the low carbon version of A312 TP316 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). A312 TP316L 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. TP316L 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.
We can also supply A312 TP316/316L Dual Grade Pipes from ABS,BV,DNV-GL class approved makers,Mill test certificate EN 10204 3.1 /3.2 certificate will be provided
