Accurate Engineering INDUSTRIES is stockist, supplier & distributor of Marine Grade Stainless Steel Tube that are widely used for marine applications. We are also exporter & distributor of 316 marine grade stainless steel tube. In a marine environment, Stainless Steel Marine Tube Material must be made clear as to whether the stainless steel is submerged in seawater or is simply near enough to the seashore such that it can be attacked by the chloride present in seawater by splashing or carried by the onshore breeze. Accurate Engineering Industries is well known as Marine Grade SS Tubing manufacturer in India.As the largest stockholder of marine grade Tube. Near the seashore, Marine Grade SS Tubing has typically considered the minimum grade of for use in such a marine environment.

Grade 304l is probably the most common grade of stainless steel used in marine applications.316 marine grade stainless steel tube has more molybdenum than other austenitic stainless steels which helps it to resist pitting and other corrosive effects of salt water. Grade 316 is another marine grade stainless steel Tube, although it has less molybdenum than grade 304 making it a less desirable choice in chlorine-rich environments.
Marine Grade SS Tubes are finished in accordance with customer needs regarding dimensional and wall thickness specifications as well as heat treatment for more demanding applications. In general a Marine Grade Stainless Steel Tube is manufactured according Marine Grade 316, Marine Grade 304, and Marine Grade 316 L standards API, ASTM, and ASME.
