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.

Compared to 316L tube, the tensile strength and yield strength of 316L Mod tube are generally higher, providing better overall strength and resistance to deformation under load. Additionally, the material maintains good ductility with a similar or slightly better elongation percentage, making it suitable for welding and forming.

• Corrosion Resistance: 316L Mod stainless tubing is very suitable for harsh chemical environments, especially in urea production where corrosion resistance is critical. The tube is specially optimized for urea production process and has better resistance to ammonia and urea solution, which are common corrosive agents in urea manufacturing process. Additionally, 316L Mod reduces the risk of carbide precipitation during welding, improving the material’s resistance to intergranular corrosion at welded joints, making it ideal for welded applications in urea production equipment

• High-temperature Resistance: 316L Mod is also known as 1.4435 stainless steel, with a higher molybdenum content,  which can better maintain mechanical strength and oxidation resistance at high temperatures. At the same time, the improved high-temperature performance of 316L Mod helps prevent material degradation, ensuring durability and reliability even in harsh thermal conditions. This makes 316L Mod tube particularly suitable for use in industries such as urea production, chemical processing, and power generation, where high-temperature stability is critical.

• Excellent Machinability: The stainless steel 316L Mod's fully austenitic microstructure ensures that it can be easily cold-formed and welded without major issues. 316L Mod stainless steel tube made of this material can also be welded using various methods, including TIG, MIG, plasma, and SMAW, but requires careful control to avoid hot cracking and ensure low ferrite content, no carbide or nitride precipitation, and minimal intermetallic phase formation.

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.
