Product Introduction
316L stainless steel, a type of austenitic stainless steel, is obtained by adding 2% to 3% molybdenum to 304 stainless steel. This modification significantly enhances the material's corrosion resistance in seawater and chloride environments, especially at high temperatures, where its resistance to intergranular corrosion is particularly outstanding.

Product Advantages
Outstanding corrosion resistance:
Strong resistance to pitting and crevice corrosion, making it the preferred choice for chlorine-containing environments and the transportation of chemical media.
Convenient welding
No annealing treatment is required after welding, the weld strength is high, and the installation efficiency is high.
Wide adaptability
Good biocompatibility, meeting food and medical safety standards, and resistant to high pressure, high and low temperature environments.
Long service life
The surface passivation film is dense, the maintenance cost is low, and the service life is much longer than that of ordinary steel pipes.
Materials and Chemical Composition
Commonly used execution standards: ASME AS-213/SA-213M, ASME SA-312/SA-312, ASTM A312, GB/T14976

The molybdenum element significantly enhances resistance to seawater and chloride corrosion, and the low-carbon design prevents intergranular corrosion after welding. Its corrosion resistance far exceeds that of ordinary stainless steel pipes, making it suitable for complex medium transportation scenarios.
