Company News

316 and 316L stainless steels are molybdenum-containing stainless steels. The molybdenum content of 316L stainless steel is slightly higher than that of 316 stainless steel. Due to the molybdenum content in the steel, the overall performance of the steel is better than 310 and 304 stainless steel. Under high temperature conditions, when the sulfuric acid concentration is lower than 15% and higher than 85%, 316 stainless steel has a wide range of uses. 316 stainless steel also has good resistance to chloride attack, so 316 Stainless Steel Sheet is usually used in marine environments. 316L stainless steel has a maximum carbon content of 0.03, which can be used in applications that cannot be annealed after welding and require maximum corrosion resistance.
1. Corrosion resistance:
Corrosion resistance is better than 304 stainless steel, and has good corrosion resistance in pulp and paper production. 316 stainless steel is also resistant to marine erosion and aggressive industrial atmospheres.
2. Heat resistance:
In intermittent use up to 1600 degrees and continuous use below 1700 degrees, 316 stainless steel has good oxidation resistance. In the range of 800-1575 degrees, 316 stainless steel is preferably applied discontinuously, but when 316 stainless steel is continuously used outside the temperature range, the stainless steel has good heat resistance. 316l Stainless Steel Sheet has better carbide precipitation resistance than 316 stainless steel, and can use the above temperature range.

3. Heat treatment:
Annealing is performed in a temperature range of 1850-2050°C, then rapid annealing, and then rapid cooling. 316 stainless steel cannot be hardened by heat treatment.
4. Welding:
316 stainless steel has good welding performance. All standard welding methods can be used for welding. Welding can be based on the use of 316Cb, 316L or 309Cb stainless steel filler rods or electrodes. In order to obtain the best corrosion resistance, the welding section of 316 stainless steel needs post-weld annealing. If 316L stainless steel is used, post-weld annealing is not required.
Typical use:
Pulp and paper equipment heat exchangers, dyeing equipment, film processing equipment, pipes, building exterior walls in coastal areas.
