Aisi Type 316ln Stainless Steel, Composition Spec

We produce ASTM/ASME Grade 304, Grade 304L,304h, 316, 316L, 316H, 316TI, 321, 321H, 309S, 309H, 310S, 310H, 410S, 2205, 904L, 2507, 254, gh3030, 625, 253MA, S30815, 317L, Type 317, 316lN, 8020, 800, 800H, C276, S32304 and others special requirement stainless steel grade.

From normal grades of group 316 it’s distinguished by significantly better resistance to chlorides, sea water, acids, cracks and product fatigue during work. In addition, the improved chemical composition permits the material for use at elevated temperatures in far more aggressive environments than normal 316 metal. AISI sort 316LN austenitic stainless-steel was uncovered to flowing sodium at 798 K for 16,000 h within the bi-metallic (BIM) sodium loop. A modified floor layer of 10 μm width having a ferrite structure was detected from X-ray diffraction and electron micro probe based mostly evaluation. Beneath the modified surface layer a carburized zone of 60 μm width was recognized which was found to encompass M23C6 carbides.

AISI 316LN (1.4406) chrome steel is alloyed with nitrogen to compensate for the lack of strength. Austenitic acid-resistant steel resistant to intergranular and crevice corrosion with elevated content of Nitrogen and Molybdenum.

The primary difference between AISI 316 (1.4401) stainless-steel and AISI 316L (1.4404) stainless-steel is the carbon content material. Due to decrease carbon amount AISI 316L (1.4404) chrome steel has reduced danger of sensitization (grain boundary carbide precipitation) but at the similar time, it loses some of its power.

The mechanical properties of grade 316LN stainless-steel are displayed within the following table. The following datasheet supplies an outline of stainless-steel grade 316LN.

A mathematical model based mostly on finite distinction technique was developed to predict the carburization profiles in sodium exposed austenitic stainless steel. In the computation, impact of solely chromium on carbon diffusion was thought of. Amount of carbon remaining in answer was decided from the solubility parameter.

Stainless steel grade 316LN is an austenitic type of metal that may be a low carbon, nitrogen-enhanced model of grade 316 metal. The nitrogen content material in this metal supplies strong solution hardening, and raises its minimum specified yield power. It additionally possesses good resistance to basic corrosion and pitting/crevice corrosion. AISI 316 (1.4401), AISI 316L (1.4404) and AISI 316LN (1.4406) are Cr-Ni-Mo austenitic stainless steels, that are generally used as a result of their excellent corrosion resistance in varied aggressive environments.

The predicted profile showed a fairly good match with the experimental profile. Calculations have been prolonged to simulate the thickness of the carburized layer after publicity to sodium for a interval of forty years. Attempt was also made to foretell the carburization profiles primarily based on equilibrium calculations using Dictra and Thermocalc which contain each thermodynamic and kinetic databases for the system into account. Boltport fasteners supply Austenitic Stainless Steel 316ln bolts and nuts with standard and customized manufacturing to your specification. The chemical composition of grade 316LN chrome steel is outlined in the following table.
