316L is a stainless steel material grade, AISI 316L is the corresponding American grade, and sus 316L is the corresponding Japanese grade.

This stainless steel is also a derivative of 18-8 austenitic stainless steel, with 2 to 3% Mo added.

Chemical Composition:

Grade Standard C Si Mn P S Cr Ni Mo
316L ASTM A240 ≤0.03 ≤1.00 ≤2.00 ≤0.045 ≤0.030 16.00-18.00 10.00-14.00 2.00-3.00

Parts of the passivation film on the surface of the 316L stainless steel plate with weak corrosion resistance will form pitting corrosion reactions due to self-excited reactions, resulting in small holes. In addition, fluorine ions will approach, forming a very corrosive solution, accelerating the corrosion reaction. speed. There is also intergranular corrosion and cracking inside the stainless steel, all of which have a destructive effect on the passivation film on the surface of the stainless steel plate.

Therefore, the stainless steel surface must be cleaned and maintained regularly to maintain its gorgeous surface and extend its service life.

316L stainless steel is widely used in various fields that require good corrosion resistance. For example, in marine engineering, it is often used to manufacture structural components of ships, offshore platforms and other equipment; in the chemical industry, it can be used to manufacture corrosion-resistant pipes, valves and other equipment; in the food processing industry, it can be used to manufacture food processing equipment , tableware, etc.

Quanshuo Metal Materials is a manufacturer that has passed ISO9001:2015, TUV, SGS, and CE certification. It mainly produces Stainless Steel, etc., with an annual output of 300,000 tons. Looking forward to your inquiry.
