Stainless Steel Grade 316

Its primary alloying constituents after iron are chromium between 16 18 nickel 10 12 and molybdenum 2 3 with small 1 quantities of silicon phosphorus sulfur also present.

Stainless steel grade 316. Some common types are the l f n and h variants. Grade 316 is an improved version of cs 304 with the addition of molybdenum and a slightly higher nickel content. Stainless steel grade 316 grade 316 316l technical data summary. 276 is a group of iron based alloys that contain a minimum of approximately 11 chromium.

Similar to 304 grade 316 stainless steel has high amounts of chromium and nickel. 316 also contains silicon manganese and carbon with the majority of the composition being iron. Each is slightly different and each is used for different purposes. A major difference between 304 and 316 stainless steel is the chemical composition with 316 containing a significant amount of molybdenum.

Sae 316l grade stainless steel sometimes referred to as a4 stainless steel or marine grade stainless steel is the second most common austenitic stainless steel after 304 a2 stainless steel. There is a variety of different types of 316 stainless steel. Marine grade stainless steel called type 316 is resistant to certain types of corrosive environments. The key difference is that 316 stainless steel incorporates about 2 to 3 percent molybdenum.

3 different types of stainless steel include the elements carbon from 0 03 to greater than 1 00 nitrogen aluminium silicon sulfur titanium nickel copper selenium niobium. Grade 316 is the standard molybdenum bearing grade second in importance to 304 amongst the austenitic stainless steels. 316 stainless steel is an austenitic chromium nickel stainless and heat resisting steel with remarkable resistance to corrosion in comparison to other steels when exposed to the outdoor elements like sea water. 3 a composition that prevents the iron from rusting as well as providing heat resistant properties.

316 grade is the second most common form of stainless steel. 316 grade stainless steel is commonly used in the manufacturing of furnace pieces exhaust manifolds photographic and pharmaceutical machinery as well as parts of jet engines. The resultant composition of cs 316 gives the steel much increased corrosion resistance in many aggressive environments. Grade 316 stainless steel is designed for extreme environments or those industries that require stronger protection and corrosion resistance than stainless steel under the 300 series.

The molybdenum gives 316 better overall corrosion resistant properties than grade 304 particularly higher resistance to pitting and crevice corrosion in chloride environments.
