Stainless Steel - Grade 316 Technical Data
Grade 316 is an improved version of CS 304, with the addition of molybdenum and a slightly higher nickel content. The resultant composition of CS 316 gives the steel much increased corrosion resistance in many aggressive environments. The molybdenum makes the steel more resistant to pitting and crevice corrosion in chloride-contaminated media, sea water and acetic acid vapours. The lower rate of general corrosion in mildly corrosive environments gives the steel good atmospheric corrosion resistance in polluted marine atmospheres.
CS 316 offers higher strength and better creep resistance at higher temperatures than CS 304. CS 316 also possesses excellent mechanical and corrosion properties at sub-zero temperatures. When there is a danger of corrosion in the heat-affected zones of weldments, the low-carbon variety CS 316L should be used. CS 316 Ti, the titanium-stabilised version, is used for its resistance to sensitization during prolonged exposure in the 550oC-800oC temperature range.
Because of its superior corrosion and oxidation resistance, good mechanical properties and fabricability, CS 316 has applications in many sectors of industry. Some of these include:
Tanks and storage vessels for corrosive liquids.
Specialised process equipment in the chemical, food, paper, mining, pharmaceutical and petroleum industries.
Architectural applications in highly corrosive environments.
