300-word Mechanical Properties of AISI 316N and AISI 316LN Steel at Room Temperature

AISI 316N (00Cr17Ni12Mo2N) and AISI 316LN (00Cr17Ni13Mo2N) are two of the most commonly used high-alloy austenitic stainless steels. These steels are known for their good corrosion resistance and exceptional mechanical properties at both room temperature and elevated temperatures.

At room temperature, AISI 316N and AISI 316LN steels have an 0.2 percent proof strength of 185 ksi and an ultimate tensile strength of 70 ksi. For both steel grades, the yield strength is 40 ksi. The yield strength represents the point of deformation where permanent deformation occurs without any additional load being applied. The ductility of these steels is evaluated with the elongation test. Elongation tests have proven that these two steel grades have an average total elongation at break of around 55%, depending on the specific grade used.

The toughness of the AISI 316N and AISI 316LN steels is assessed using the Charpy V impact test, with ideal results in the range of 20 - 40 foot-pounds (ft-lbs). For toughness classification purposes, AISI 316N steel is also known as level 1 and AISI 316LN steel falls into the level 2 category. The Charpy V test measures the percentage of ductile fracture in the material, which is important in evaluating the behavior of the steel when exposed to sudden and/or significant temperature changes.

The hardness of AISI 316N and AISI 316LN at room temperature is evaluated using the Rockwell C test. With this test, the steel is normally required to have a hardeness of between 25 and 45 Rockwell C (HRC). For these steel grades, the average hardness at room temperature is typically on the lower end of this scale, at around 30 HRC.

Overall, AISI 316N and AISI 316LN steels have good mechanical properties at room temperature, with an exceptional strength-to-weight ratio and a good level of ductility and toughness. This makes these steels a popular choice for many applications requiring high strength, excellent corrosion resistance and good mechanical properties at both low and elevated temperatures.
