316L Stainless Steel Tube Pipe

Grade 316L, the low carbon version of 316 and has very high immunity from sensitization (grain boundary carbide precipitation). It is extensively used in the oil and gas and chemical industries for its cost effective corrosion resistance and ease of fabrication. There is commonly no appreciable price difference between 316 and 316L stainless steel. The austenitic structure also gives these grades excellent toughness, even down to cryogenic temperatures. Compared to chromium-nickel austenitic stainless steels, 316L stainless steel offers higher creep, stress to rupture and tensile strength at elevated temperatures.


These alloys may be considered for a wide variety of applications where one or more properties are important.

Welding
Excellent weld ability by all standard fusion and resistance methods, both with and without filler metals. Heavy welded sections in Grade 316 require post-weld annealing for maximum corrosion resistance. This is not required for 316L.

316L stainless steel is not generally weldable using oxyacetylene welding methods.

Machining
316L stainless steel tends to work harden if machined too quickly. For this reason low speeds and constant feed rates are recommended.

316L stainless steel is also easier to machine compared to 316 stainless steel due its lower carbon content.

Hot and Cold Working
316L stainless steel can be hot worked using most common hot working techniques. Optimal hot working temperatures should be in the range 1150-1260°C, and certainly should not be less than 930°C. Post work annealing should be carried out to induce maximum corrosion resistance.

Most common cold working operations such as shearing, drawing and stamping can be performed on 316L stainless steel. Post work annealing should be carried out to remove internal stresses.

Hardening and Work Hardening
316L stainless steel does not harden in response to heat treatments. It can be hardened by cold working, which can also result in increased strength.
