Wire Rods Corrosion Resistance

Wire Rods Corrosion resistance

316 and 317 stainless steel (317 stainless steel performance see below) is molybdenum stainless steel. 317 stainless steel molybdenum content is slightly higher in the 316 stainless steel due to the molybdenum steel, the steel's overall performance is better than 310 and 304 stainless steel, high temperature conditions, when the sulfuric acid concentration of less than 15% and higher 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 environments.

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

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 erosion of marine and erosive industrial atmospheres.

Heat resistance

In the continuous use of 1600 degrees below the continuous use and below 1700 degrees in the 316 stainless steel has good resistance to oxidation. In the range of 800-1575 degrees, it is best not to continuously use 316 stainless steel, but in the temperature range outside the continuous use of 316 stainless steel, the stainless steel has good heat resistance. 316L stainless steel resistance to carbide precipitation better than 316 stainless steel, available above the temperature range.

Heat treatment

Annealing at a temperature in the range of 1850 to 2050 degrees, then rapidly annealing, and then rapidly cooling. 316 stainless steel can not be superheated to harden.

welding

316 stainless steel has good welding performance. All standard welding methods can be used for welding. Welding can be used according to the use of 316Cb, 316L or 309Cb stainless steel packing rod or welding electrodes for welding. For optimum corrosion resistance, 316 stainless steel welded sections need to be post-weld annealed. If 316L stainless steel is used, no post-weld annealing is required.

Typical use

Equipment for pulp and papermaking Heat exchangers, dyeing equipment, film flushing equipment, pipelines, coastal areas Building materials for external use. For the more rational use of metal materials, give full play to its role, we must grasp the various metal materials made of zero, the normal operation of the components should have the performance (performance) and its hot and cold process in the material should have the performance (Process performance).

Material properties include physical properties (such as specific gravity, melting point, conductivity, thermal conductivity, thermal expansion, magnetic, etc.), chemical properties (durability corrosion resistance, oxidation resistance), mechanical properties, also known as mechanical properties.

Material process performance refers to the ability of materials to adapt to cold and hot working methods.

(A), mechanical properties

Mechanical properties refers to the metal material under the action of external forces shown by the characteristics.

1, strength: the material in the external force (load) under the action of resistance to deformation and fracture capacity. The unit area of the material is stressed by the load.

2, the yield point (бs): that yield strength, refers to the material in the stretch process, the material subjected to stress to a certain critical value, the load is no longer increase the deformation is continued to increase or produce 0.2% L. The stress value is expressed in units of Newton / mm 2 (N / mm2).
