ASTM A312 TP 316L Stainless Steel Seamless Pipe price
Useful Information:
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.
316 is usually regarded as the standard “marine grade stainless steel", but it is not resistant to warm sea water. In many marine environments 316 does exhibit surface corrosion, usually visible as brown staining. This is particularly associated with crevices and rough surface finish.
Characteristics
- Higher creep resistance
- Excellent formability and weld ability
- Rapture and tensile strength at high temperatures
- Corrosion and pitting resistance
- Exceptional resistance in acid and hand water areas
Market applications:
- Chemical & pharmaceutical
- Refining oil & gas
- Instrument construction and engineering products
- Shipbuilding and hydraulics construction and engineering products
- Paper industry digesters, evaporators & handling equipment
- Surgical and medical tools
Seamless Pipe benefits
1) Pressure Ratings
The greatest advantage of seamless steel pipes is their increased ability to withstand pressure. The weakest point in a welded steel pipe is the welded seam. But because a seamless steel pipe has not been welded, it doesn’t have that seam, making it equally strong around the entire circumference of the pipe.
It is also much easier to determine pressure calculations without being required to take weld quality into consideration.
Although seamless pipe can sometimes be more expensive than welded pipe, this increased ability to withstand pressure allows you to use pipes that are thinner and lighter, which can help cut down on expenses.
2) Uniformity of Shape
Because welded seam pipe is wrapped around another form before it is welded, and because welding adds heat, stress and other extraneous variables to the forming process, it can never be as round as seamless steel pipe.
Seamless steel pipe is a continuous extrusion of the alloy, meaning that it will have a round cross section that you can count on, which is helpful when you’re installing pipes or adding fittings.
3) Strength Under Loads
Seamless steel pipe can sometimes be more expensive than other forms of steel pipe, but it’s also more reliable.
This is because it has greater strength under loading. Empty pipe must always support its own weight, but when a pipe is filled with material–or under load–it must also support that weight as well. Pipe failures and leaks in welded pipes usually occur at the welded seam. But because seamless pipe doesn’t have that seam, it isn’t subject to those failures.
4) Production Processes
Seamless pipes are manufactured using different procedures, depending on the diameter or the ratio of diameter to wall thickness. The normal raw material is a round spool section preheated in a rotary furnace, or for larger diameters a hollow section preshaped in a perforation press, which is then prerolled in a rotary rolling mill. In the manufacture of longitudinally welded pipes, either individual steel plates or coils are used as raw material. The pipes are produced in a series of different, sequenced process stages, including cold forming, welding, heat treatment, calibration and non-destructive testing.
5) Pipe Lengths and Quantities
When manufacturing seamless pipes, the length manufactured depends on the weight per metre or per rod. Thus up to NB 100, pipe lengths of a maximum 13 m, and up to NB 200 pipe lengths of a maximum of around 4 m can be produced. The minimum purchase quantity is determined by the size of the production batch of around 1 t.
