316L heavy wall stainless steel tube 


316L stainless steel thick walled tube, which material is 316L stainless steel, 

belongs to Molybdenum stainless steels, which performance better than type 304 and 310 stainless steel. 

At high temperatures, when the concentration of sulfuric acid less than 15% and more than 85%, 

the 316L stainless steels usually should be used widely. 

Besides, with a good corrosion chlorides performance, 

this grade of stainless steel usually is used in marine environment.

Name: thick-walled inox 316l tube, stainless steel tubing wall thickness

OD(out diameter): 6-830mm

Wall Thickness 0.5-55 mm.

Solution Treatment: 1010~11500 ℃

Carbon content: no more than 0.03%

Melting Point: 1375-14500 ℃

Heat Resistance  ---

When indirectly using under 1600℃ and continuously using under 1700℃, 

the 316L stainless steel has favorable oxidation resistance. 

When heat range 800℃-1575℃, It is best not to use continuously 316L stainless 

steel products. If out of that range, this stainless steel has good heat 

resistance with high strength properties.

Heat Treatment  ---

Annealing temperature range 1850℃ - 2050℃,then quickly cooling.

Please attention, 316L stainless steels can't be hardened through heat treatment.

Welding filler ---

Adopt a standard welding method, can use 316Cb, 316L or 309Cb stainless steel 

fillers or welding rods. In order to achieve the optimal anticorrosion, 316 

materials welding section need to be treated through annealing, but 316L 

materials not need.

heavy wall tube Application  ---

Paper making, heat exchanger, dyeing equipments and conditions, film swilling 

machine, Piping assembly, construction outside materials in low-lying and coastal 


Chemical Component  ---

C≤0.03   Si≤1.00  Mn≤2.00  P≤0.035  S≤0.03  Ni:12.0-15.0   Cr:16.0-18.0


Delivery state --

Annealing with solution treatment
