Yet, at the same time, it loses some of its strength.ĪISI 316LN (1.4406) stainless steel is alloyed with nitrogen to compensate for the loss of strength. In addition, this stainless steel paint coating can be exposed to high.

The 'L' stands for 'low carbon' content.ĭue to the lower carbon amount, AISI 316L (1.4404) stainless steel has a reduced risk of sensitization (grain boundary carbide precipitation). Also known as surgical stainless steel, marine steel, 316S16 (as per the British Standard), SS 316 is an austenitic chromium-nickel alloy. SS-316 is rated the highest in corrosion proof coating for salt spray resistance. It is considerably more resistant to solutions of sulfuric acid, chlorides, bromides, iodides and fatty acids at high temperature. Type 316 is durable, easy-to-fabricate, clean, weld and finish. The main difference between AISI 316 (1.4401) stainless steel and AISI 316L (1.4404) stainless steel is the carbon content. Since Type 316 stainless steel alloy contains molybdenum bearing it has a greater resistance to chemical attack than 304. Grade 316 is an austenitic grade second only to 304 in commercial importance.

The molybdenum gives 316 better overall corrosion resistant properties than Grade 304, particularly higher resistance to pitting and crevice corrosion in chloride environments. Differences between AISI 316 (1.4401), AISI 316L (1.4404) and AISI 316LN (1.4406) Grade 316 is the standard molybdenum-bearing austenitic grade, second stainless steel in importance to 304. What are AISI 316 (1.4401), AISI 316L (1.4404) and AISI 316LN (1.4406)?ĪISI 316 (1.4401), AISI 316L (1.4404) and AISI 316LN (1.4406) are Cr-Ni-Mo austenitic stainless steels, which are commonly used due to their very good corrosion resistance in various aggressive environments.
