{Tissue corrosion:Hoja de acero inoxidable T316
Tissue corrosion is also called intergranular corrosion. In austenitic stainless steel or austenite and ferrite dual phase steel, carbon elements in steel are dissolved in austenite with heating, as in hot rolling process, steel is heated to 1000-1200 degrees C, carbon elements begin to dissolve in austenite at 900 degrees C, and carbon elements at 1050 C are completely dissolved in austenite. However, during the cooling process, carbon is precipitated from austenite and combined with chromium at the intergranular sites to form carbide of Cr23C6. The chromium content in the intergranular zone is reduced, resulting in the phenomenon of poor chromium and also the function of anti rust.
Stress corrosion:201 mosaico de hoja de acero inoxidable en foshan
The residual stress in the steel base will cause uneven performance of the stainless steel during hot rolling deformation, cold drawing deformation, cold rolling deformation and heat treatment process. Especially for cold deformation surface, because of lattice variation, it is easy to be damaged by external environment (such as friction, scratch, collision, erosion and corrosion concentration) and superposition of additional stress greater than intergranular atomic force.316 16 ga proveedor de hoja de acero inoxidable
