316, 316L & 316H Seamless Steel Tube & Pipe
Grade 316 is a normal molybdenum-bearing grade, second inoverall volume production to 304 amongst the austenitic stainless steels. The grade gives the 316 stainless steel a great overall corrosion and rust resistant properties than Grade 304, principally higher resistance to pitting and crevice corrosion in chloride workplace environments.
It is ready to be brake or roll formed, welded, soldered and cut by both modern thermal and mechanical methods. The austenitic grade structure gives excellent durability and robustness, even down to cryogenic temperatures
Grade 316L is a low carbon type of low carbon version of the basic grade 316. It is highly resistant to sensitisation (grain boundary carbide precipitation) and is widely used in heavy gauge welded components (around 5mm +).
Grade 316H, with its higher carbon content has some application at elevated temperatures (as does grade 316Ti). Nitrogen-strengthened versions also exist as 316N and 316LN. Only 316 and 316L are readily available in Australian stock.
Grade 316H, has a higher carbon content than the base 316 grade and is applicable at elevated temperatures, (Please not 316Ti is also similar). Nitrogen-strengthened types also exist as 316N and 316LN.
316 Stainless Steel Grade Pipe
This pipe belongs to the 300 series of pipes, specifically grade 316. This series of pipes are used widely, most of them have a strength of corrosion resistance, heat resistance and good chemical performance.
