Introduction
00Cr17Ni14Mo2(316L, UG) steel is a kind of austenitic stainless steel that contains higher chromium content, and its corrosion resistance and durability are better than those of the conventional 300 series stainless steels. Therefore, it is widely used in welding, aerospace and automobile industries. Additionally, it is usually used to make containers and reaction vessels by welding, and its durability and tarnish resistance are good enough for it to be applied to general engineering applications, such as oil refining and petrochemical pipelines, cooling ocean engineering and chemical fertilizer plants.
00Cr17Ni14Mo2(316L, UG) steel is also known as marine grade steel due to its good antifouling, erosion and corrosion prevention properties in seawater. It can resist the corrosion of most organic and inorganic acids and saline compounds in low and average concentrations, and is also resistant to sulfuric and hydrochloric acids in relatively low concentrations. However, when it is exposed to a chloride-containing environment with a higher stress level, it is easier to cause pitting and crevice corrosion.
