Industrial titanium container corrosion associated Detailed knowledge

Industrial titanium plates for sale container corrosion refers to the environment must, metal and the surrounding medium resulting in the onset of the chemical may damage the electrochemical reaction. In a corrosive environment, when industrial titanium container is not the time to pick, it will also attack corrosion.

Which affect carbon austenitic titanium container industry: carbon in austenite titanium container industry is intense and stable austenite and constitute an extension element austenite region. Carbons nickel austenite to about 30 times, the carbon element is a gap, through solid solution strengthening can be significant progress austenite industrial strength titanium container. Carbon titanium container industry also advances austenite stress corrosion function in a high concentration of chloride (eg 42% MgCl2 jubilation solution). However, in austenitic industrial titanium vessel, carbon is often regarded as harmful elements, which is due to the primary container and the titanium plate in the industrial use of some of the corrosion conditions (for example heat welding or by 450 ~ 850 ℃), carbon carbon compounds may constitute Cr23C6 high chromium and chromium and titanium plate suppliers chromium depleted resulting in some, especially the corrosion resistance of titanium is resistance to intergranular corrosion function decline. Thus, the Cr-Ni austenitic titanium container industry since the 1960s, new developments are mostly carbon content of less than 0.03% or 0.02% ultra-low carbon type, it is possible to know to follow the carbon content decreased, intergranular corrosion sensitive titanium decreased, when the carbon content is less than 0.02% it has the most significant effect, some tests pearlescent also noted that carbon also increases austenite industrial point chromium titanium container corrosion points tendency. Due to the harmful effects of carbon, not only industrial titanium in austenitic container workout and the demand should be controlled as low carbon content, and in the subsequent heat, cold working and heat treatment process are avoided by the outer container industry titanium carbon and chromium carbide-free separation.

Corrosion classification are the following:

1, according to the nature of the effect can be divided into chemical and electrochemical corrosion.

2, according to the shape of corrosion can be divided generally (full uniform) corrosion. Typically called corrosion, corrosion system measures scattered throughout the container industry titanium exterior, the so-called partial corrosion pitting, crevice corrosion, stress corrosion cracking, corrosion fatigue, the selection of corrosion, erosion and corrosion.

3, according to the onset of corrosion environment and conditions can be divided into atmospheric corrosion, industrial water erosion and soil erosion. Acid and alkali. Salt corrosion, seawater corrosion, high temperature corrosion, (including the liquid metal, molten salt, gas corrosion) and so on.
