SS 316 1.4401 1.4436 Seamless Pipe
Stainless steel types 1.4401 (also known as grade 316) Seamless pipe is an austenitic grade second only to 304 in commercial importance. 316 stainless steel contains an addition of molybdenum that gives it improved corrosion resistance. This is particularly apparent for pitting and crevice corrosion in chloride environments.Grade 321 stainless steel (1.4541) is a heat resistant grade supplied into numerous industry sectors.

SS 316 1.4401 1.4436 Seamless Pipe
The Stainless Steel 316 Seamless Pipe is designed with a superior content of 16-18% chromium, 10-12% nickel with 2-3% of molybdenum. The outstanding content embedded in the SS 316 Pipe gives them enhanced corrosion and oxidation resistance properties in an array of environments. The versatile Marine Stainless Steel Pipe has good tolerance to reducing acids, crevice corrosion, and pitting by acids in marine systems. The robust 316 Stainless Steel Tube exhibits intermittent service temperatures of between 870 degrees C up to 925 degrees C. The grade of Stainless Steel 316 Tube can work well in continuous temperatures between 425-860 degrees C. These tubes can be readily welded in place following standard welding procedures. 316 Stainless Steel Pipe is designed with excellent mechanical properties. These pipes have a minimum tensile strength of 515mpa with a minimum yield strength of 205mpa. This 316 Stainless Steel Pipe can be readily elongated by 40% while showcasing a density of 8.0 kg/m3. They have a hardness of 217 max Brinell. SS 316 Pipe cannot be hardened by standard thermal treatment. These pipes are annealed at temperatures between 1010 up to 1120 degrees C, followed by rapid cooling.

316 Stainless Steel Tubing Temperature Rating
316 has good oxidation resistance in intermittent service up to 1600°F and in continuous service to 1700°F. Continuous use of type 316 in the 850° F to 1550°F temperature range is not recommended due to possibility of carbide precipitation but performs well in temperatures fluctuating above and below this range.
