Stainless Steel 347/347H Pipes

Silver Tubes is a leading Exporter and manufacturer of Stainless Steel 347 Pipes / Stainless Steel 347H Pipes, which is a stabilized stainless steel which offers as its main advantage an excellent resistance to intergranular corrosion. Similar to SS 321, these SS 347 Pipes uses columbium as a stabilizing element to maximize its principal feature: resistance to intergranular corrosion. SS 347H Pipes is also advantageous for high temperature service because of its good mechanical properties. Applications for Type 347 Pipes include those for welded construction and parts subjected to heating in the carbide precipitation range, aircraft collector rings, aircraft exhaust stacks,and so on. Applications of Type 347H Pipes include boiler casings, cabin heaters, carburetor air intensifier tubes, exhaust manifolds, fasteners, fire walls and flash boilers.

These Grade 347 Pipes also are used for parts which are intermittently heated and cooled to temperatures between 800 degree F and 1600 degree F. Grade 347H Pipes can be used in applications requiring repeated heating in the range of 427 Degree C -899 Degree C). Alloy 347 Pipes offers higher creep and stress rupture properties than Alloy 304. Meanwhile, these Alloy 347H Pipes can consider for exposures where sensitization and intergranular corrosion are concerns.347 Stainless Steel Pipes is generally used for parts which are intermittently heated up to 1500 degree F. 347H Stainless Steel Pipes offers good mechanical properties with higher creep and stress rupture characteristics than other grades.
