316H Stainless Steel Pipe Manufacturer & Supplier
316H Stainless Steel Pipe is a variant of 316 stainless steel with a higher carbon content, making it more suitable for applications involving elevated temperatures. Stabilized Grade 316Ti offers similar qualities.
The increased carbon content provides greater tensile and yield strength. Additionally, the austenitic structure of this grade imparts excellent toughness, even at cryogenic temperatures.
This steel is well-suited for use in the petrochemical, gas, and chemical industries. Prosaic Steel supplies Grade 316H to various customers, including pressure vessel fabricators and industrial applications.
Benefits of using Type 316H Stainless Steel:
- Enhanced heat resistance due to increased carbon content
- Higher tensile and yield strength
- Improved short and long-term creep strength
Prosaic Steel offers 316H Stainless Steel Pipe, 316H Stainless Steel Seamless Pipe, 316H Stainless Steel Tube, and is a manufacturer of these products. They also provide Stainless Steel DIN Seamless Tubes, SS UNS S31609 Seamless Tubing, SS 316H Cold Drawn Tubes, and SS 316H Seamless Tubing in India.
Background of 316H Stainless Steel Pipes
Grade 316 is an austenitic stainless steel and is considered the standard molybdenum-bearing grade, second in importance only to Grade 304. The addition of molybdenum enhances its corrosion resistance compared to Grade 304, particularly in chloride environments, providing better resistance to pitting and crevice corrosion. It exhibits excellent formability and weldability, making it suitable for various applications in industrial, architectural, and transportation sectors. Grade 316 is easily formed into different parts through brake or roll forming. Moreover, it boasts exceptional welding characteristics, eliminating the need for post-weld annealing in thin sections.
Grade 316L is the low carbon version of 316, which prevents sensitization (precipitation of grain boundary carbides). This makes it highly suitable for heavy gauge welded components, especially those exceeding 6mm in thickness. On the other hand, Grade 316H contains a higher carbon content and finds applications at elevated temperatures, similar to the stabilized grade 316Ti.
The austenitic structure of these grades also imparts excellent toughness, even at cryogenic temperatures.
