316L Mod tube is an enhanced version of 316L tube, belongs to urea-grade austenitic stainlee steel. the key differences include slightly higher levels of molybdenum (Mo), which enhance corrosion resistance, especially against chloride-induced pitting and crevice corrosion. It may also have increased levels of silicon (Si), improving high-temperature strength and oxidation resistance.

The steel 316L Mod is also known as S31723 stainless steel, widely used in industries requiring highly corrosive resistance, high temperatures and high pressures resistance, such as urea production. Thus, for 316L Mod urea-grade austenitic stainless steel tube, specific surface treatment is essential to improve its corrosion resistance and ensure the long-term stability and reliability. Common surface finishes include Acid Pickling (AP), Mechanical Polishing (MP), Bright Annealed (BA), and Electropolished (EP).
The widespread application of 316L stainless steel tube & pipe in industries such as chemical, marine, food and medical is attributed to its enhanced durability, corrosion resistance and manufacturing versatility. It is highly reliable in withstanding harsh conditions, maintaining cleanliness standards and ensuring operational efficiency to meet the demanding environments of these industries.
