Performance Difference Between 316 And 316l Stainless Steel Tube

Nov. 15, 2018

Corrosion resistance

Corrosion resistance is better than 304 stainless steel, with good corrosion resistance in the production process of pulp and paper. Moreover, 316 Stainless Steel Tubing is also resistant to erosion by marine and aggressive industrial atmospheres.

Heat resistance

316 stainless steel has good oxidation resistance in intermittent use below 1600 °C and continuous use below 1700 °C. In the range of 800-1575 degrees, it is preferable not to continuously apply 316 stainless steel, but when 316 stainless steel is continuously used outside this temperature range, the stainless steel has good heat resistance. 316l Stainless Steel Tube has better carbide precipitation resistance than 316 stainless steel and can be used in the above temperature range.

Heat treatment

Annealing is carried out at a temperature ranging from 1850 to 2050 degrees, followed by rapid annealing and rapid cooling. 316 stainless steel cannot be hardened by heat treatment.

welding

316 stainless steel has good welding properties. All standard welding methods can be used for welding. When welding, 316Cb, 316L or 309Cb stainless steel filler rods or welding rods can be used for welding according to the application. For best corrosion resistance, the welded section of 316 stainless steel requires post-weld annealing. If 316L stainless steel is used, post-weld annealing is not required.
