Introduction
Specification

Product description:

Grade 316 is the standard molybdenum-bearing grade, second in importance to 304 amongst the austenitic stainless steels. The molybdenum gives 316 better overall corrosion resistant properties than Grade 304, particularly higher resistance to pitting and crevice corrosion in chloride environments. It has excellent forming and welding characteristics. It is readily brake or roll formed into a variety of parts for applications in the industrial, architectural, and transportation fields. Grade 316 also has outstanding welding characteristics. Post-weld annealing is not required when welding thin sections.

Corrosion resistance:

Grade 316 has excellent corrosion resistance in a wide range of media. Its main advantage over grade 304 is its increased ability to resist pitting and crevice corrosion in warm chloride environments. It resists ordinary rusting in virtually all architectural applications, and is often chosen for more aggressive environments such as sea-front buildings and fittings on wharves and piers. It is also resistant to most food processing environments, can be readily cleaned, and resists organic chemicals, dye stuffs and a wide variety of inorganic chemicals.

Chemical composition

316	C	Si	Mn	P	S	Ni	Cr	Mo
316	≤0.08	≤1.00	≤2.00	≤0.045	≤0.03	10.00~14.00	16.00~18.50	2.00~3.00

Fabricability:

Grade 316 has outstanding weldability and all standard welding techniques can be used (although oxyacetylene is not normally used). Although post weld annealing is often not required to restore 316's corrosion resistance, making it suitable for heavy gauge fabrication, appropriate post-weld clean-up is recommended.

Application:

Type 316L is used in the paper-making, chemical industry, fuel, seawater equipment, oxalic acid equipment,fertilizer, photo processing equipment, food processing equipment, marine construction, etc.
