What’s up guys?!?! This is Michael with Michael Talks Metal back for a little metal mashup. Today, our video is another common stainless steel found in specifications for aerospace applications.

Type 316 and its low carbon variation 316L are austenitic stainless steels.

Another of the broadly defined “18-8” stainless steels, it is most often used in the solution annealed  condition….. aka Cond A.  Typical solution anneal is from  1850 to 2050 deg F followed by rapid cooling to prevent carbide formation.

The higher Nickel and the addition of Molybdenum allow this type to be used at higher temperatures or more corrosive environments than type 304.

316 and 316L are  considered non – magnetic in the annealed condition.

316           SAE 30316     UNS S31600

316L         SAE 30316L    UNS S31603

Density: point 29 lbs per cubic inch

Mean Coefficient of Thermal Expansion from 32 -212 deg F:

8.8 microinch per inch per deg F

Machinability rating: 42 %   (of 1212)

Chemical Composition

Carbon            0.08 % Max *

Manganese      2.00 % Max

Silicon              1.00 % Max

Phosphorus      0.04 % Max

Sulfur                0.03 % Min

Chromium        16.00 – 18.00 %

Nickel               10.00 – 14.00 %

Molybdenum     2.00 – 3.00 %

Copper              1.00% Max

* .030 for 316L

Typical  minimum mechanical properties for 316 in the annealed condition:

Yield Strength                30,000 psi

Tensile Strength             75,000 psi

Elongation                       40 %

Reduction of Area            55 %

AMS 5507: Sheet, Strip, and Plate – 316L

AMS-QQ-S-763  Bars, Shapes, and Forgings – 316 and 316L


The ASTM and ASME standards for commercial applications are too numerous to detail here.
