Basic properties of molybdenum based stainless steel

Release:tzkwbxg Browse:869times

316 and 317 stainless steel (see below the performance of 317 stainless steel) is a stainless steel containing molybdenum. 317 stainless steel molybdenum content slightly Gaoming in 316 stainless steel. Because of molybdenum in steel, the steel performance is better than 310 and 304 stainless steel, under the condition of high temperature, when the concentration of sulfuric acid is less than 15% and more than 85%, 316 stainless steel has a wide range of uses. 316 stainless steel also has a good performance of chloride erosion, so it is usually used in marine environment.

The maximum carbon content of 316L stainless steel 0.03, can be used for welding can not be annealed and the use of the need for maximum corrosion resistance

Corrosion resistance

Corrosion resistance is better than 304 stainless steel, in the pulp and paper production process has a good corrosion resistance. And 316 stainless steel is also resistant to the erosion of the ocean and the erosion of the industrial atmosphere.

Heat resistance

The 316 stainless steel has good resistance to oxidation resistance at 1600 degrees below 1700 degrees. In the range of 800-1575 degrees, it is best not to have a continuous role of 316 stainless steel, but in the temperature range of continuous use of 316 stainless steel, the stainless steel has good heat resistance. The properties of 316L stainless steel are better than that of 316 stainless steel.

Heat treatment

Annealing in the temperature range of 1850-2050 degrees, and then rapid annealing, and then rapidly cooling. 316 stainless steel can not heat treatment for hardening.

Welding

316 stainless steel has good welding performance. Can use all the standard welding method for welding. Welding can be used according to the purpose, the use of 316Cb, 316L or 309Cb stainless steel filler rod or welding electrode. In order to obtain the best corrosion resistance, the welding section of 316 stainless steel is required to be annealed. If you use 316L stainless steel, do not need to be welded after annealing.

Typical use

Equipment for pulp and paper making, dyeing equipment, film washing equipment, piping, coastal zone building materials.
