317LN stainless is a single phase austenitic (face centered cubic) stainless steel at all temperatures

up to the melting point. The alloy can not be hardened by heat treatment. The alloy is nonmagnetic in

the annealed condition. Its magnetic permeability is typically less than 1.02 at 200 H (Oersteds). Pe-

rmeability values for cold de-formed material vary with composition and the amount of cold deformation

but are usually higher than that for annealed material.

Fatigue Resistance

 

The fatigue strength or endurance limit is the maximum stress below which a material is unlikely to fail

in 10 million cycles in an air environment. For austenitic stainless steels as a group, the fatigue streng-

th is typically about 35 percent of the tensile strength. However, substantial variability in service results

is experienced since additional variables such as corrosive conditions, type of loading and mean stress

surface condition, and other factors affect fatigue properties. For this reason, no definitive endurance li-

mit value can be given which is representative of all operating conditions.

 

OXIDATION RESISTANCE

 

316LN alloy exhibits excellent resistance to oxidation and a low rate of scaling in air atmospheres at te-

mperatures up to 1600- 1650°F (870-900°C).   The performance of ATI 316LN stainless is slightly inferior

to that of ATI 304 stainless steel, which has slightly higher chromium content (18% vs. 16% for ATI 316-

LN stainless). The rate of oxidation is greatly influenced by the atmosphere en-countered in service and

by operating conditions.For this reason, no data can be presented that is applicable to service condition.

 

Like other molybdenum bearing alloys,  ATI 316LN stainless is subject to catastrophic oxidation at high

temperatures in stagnant air atmospheres, such as in the heat treatment of closely packed items. This

occurs due to the formation of low melting molybdenum trioxide (MoO3), which reacts with the alloy ca-

using deep pitting and metal loss. When air is allowed to circulate, the MoO3 will evaporate from the m-

etal surface and excessive oxidation is avoided.

 

CORROSION PROPERTIES

 

General Corrosion Resistance

 

The molybdenum bearing grades such as ATI 316 and ATI 316LN stainless steels are more resistant to

atmospheric and other mild types of corrosion than the 18Cr-8Ni stainless steels. In general, media that

do not corrode 18-8 stainless steels will not attack the molybdenum-containing grades. One known exc-

eption is highly oxidizing acids such as nitric acid to which the molybdenum bearing stainless steels ar-

e less resistant.  ATI 316 and ATI 316LN stainless are considerably more resistant than any of the other

chromium-nickel types to solutions of sulfuric acid. Where condensation of sulfur-bearing gases occurs,

these alloys are much more resistant than other types of stainless steels. In sulfuric acid solutions, the

acid concentration has a strong influence on the rate of attack.

 

Pitting Corrosion

 

Resistance of austenitic stainless steels to pitting and/ or crevice corrosion in the  presence of chloride

or other halide ions is enhanced by higher chromium (Cr) and molybdenum (Mo) content. A relative me-

asure of pitting resistance is given by the PREN (Pitting Resistance Equivalent with nitrogen) calculation

where:

 

PREN = Cr + 3.3Mo +16N

 

The PREN of ATI 316LN alloy (25.0) is higher than that of ATI 304 (PREN =20.0), reflecting the better pit-

ting resistance which ATI 316LN alloy offers due to its Mo and N content. ATI 304 stainless steel is con-

sidered to resist pitting and crevice corrosion in waters containing up to about 100 ppm chloride. ATI 316

LN alloy on the other hand, due to its Mo-content, will handle waters with up to about 2000 ppm chloride 

This alloy is not recommended for use in seawater (~19,000 ppm chloride).ATI 316LN alloy is considered

adequate for some applications that are exposed to salt spray. ATI 316LN stainless steel exhibits no evi-

dence of corrosion in the 100-hour, 5% salt spray (ASTM B117) test.

 

Intergranular Corrosion

 

ATI 317 stainless steel is susceptible to precipitation of chromium carbides in grain boundaries when ex-

posed to temperatures in the 800°F to 1500°F (425°C to 815°C) range.   Such “sensitized” steels are su-

bjerange. Stress relieving treatments falling within these limits can be employed without affecting the co-

rrosion resistance of the metal. Accelerated cooling from higher temperatures for the “L” grades is not n-

eeded when very heavy or bulky sections have been annealed.  ATI 316LN alloy possesses the same m-

echanical properties as the corresponding higher-carbon ATI 316, and offers the resistance to intergranu-

lar corrosion of ATI 316L alloy. Although the short duration heating encountered during welding or stress

relieving does not produce susceptibility to intergranular corrosion, continuous or prolonged exposure at

800-1200°F (422- 650°C) can produce sensitization of ATI 316LN (and of ATI 316L) stainless steels.

 

The influence of molybdenum reduces the resistance of ATI 316LN stainless steel to highly oxidizing en-

vironments including the nitric acid environment of the ASTM A 262 practice C "Huey" test.

 

Stress Corrosion Cracking

 

Austenitic stainless steels are susceptible to stress corrosion cracking (SCC) in halide environments. Al-

though the ATI 316,    ATI 316L and ATI 317Ti alloys are more resistant to SCC than the 18 Cr-8 Ni alloys,

they still are quite susceptible. Conditions that produce SCC are:

 

(1) Presence of halide ion (generally chloride),

(2) Residual tensile stresses, and

(3) Temperature in excess of about 140°F (60°C)

 

Stresses result from cold deformation or thermal cycles during welding. Annealing or stress relieving heat

treatments may be effective in reducing stresses, thereby reducing sensitivity to halide SCC. Although the

low carbon ATI 316L and ATI 316LN alloys offer no advantage as regards SCC resistance,   they are better

choices for service in the stress relieved condition in environments which might cause intergranular corro-

sion. If SCC resistance is desired, use of duplex stainless steels such as ATI 2205™ or ATI 2003® duplex

stainless alloys should be considered.

 

FABRICATING AND WELDING

 

Fabrication

 

The austenitic stainless steels, including the ATI 316LN alloy, are routinely fabricated into a variety of sha-

pes ranging from the very simple to very complex. These alloys are blanked, pierced, and formed on equi-

pment essentially the same as used for carbon steel. The excellent ductility of the austenitic alloys allows

them to be readily formed by bending, stretching, deep drawing and spinning.     However, because of their

greater strength and work hardenability,     the power requirements for the austenitic grades during forming

operations are considerably greater than for carbon steels. Attention to lubrication during forming of the a-

ustenitic alloys is essential to accommodate the high strength and galling tendency of these alloys.

 

Annealing

 

The austenitic stainless steels are provided in the mill-annealed condition ready for use. Heat treatment m-

ay be necessary during or after fabrication to remove the effects of cold forming or to dissolve precipitated

chromium carbides resulting from thermal exposures. For the ATI 316LN alloy the solution anneal is acco-

mplished by heating in the 1900- 2150°F (1040-1175°C) temperature range followed by air cooling or a wat-

er quench, depending on section thickness. ATI 316LN stainless cannot be hardened by heat treatment.

 

Welding

 

The austenitic stainless steels are considered the most weldable of the stainless steels. They are routinely

joined by all fusion and resistance welding processes. Two important considerations for weld joints in these

alloys are (1) avoidance of solidification cracking,     and (2) preservation of corrosion resistance of the weld

and heat-affected zones. ATI 316LN stainless steel often is welded autogenously. If filler metal must be use

for welding ATI 316LN stainless, it is advisable to utilize the low carbon ATI 316L or E318 filler metals. Cont-

amination of the weld region with copper or zinc should be avoided, since these elements can form low melt-

ing point compounds, which in turn can create weld cracking.
