  • Description : x70 line pipe


  • Stainless steel plate surface is smooth, high plasticity, toughness and mechanical strength, acid and alkali corrosion of gas, solution, and other media. It is a kind of alloy steel is not easy to rust, but not absolutely not rust.
    Stainless steel plate is weak media such as air, steam and water corrosion x70 line pipe resistance of steel, acid steel plate is refers to the chemical etching media such as acid, alkali, salt corrosion of the steel plate. Stainless steel plate since the beginning of the 20th century, has a history of more than a century. Hot-rolled and cold-rolled stainless steel plate method according to the points of two kinds, according to the characteristics of the steel grade is divided into five types: austenite size, austenitic - iron, iron, grain size, martensite, precipitation hardening type.
    Requirements can withstand the oxalic acid, sulfuric acid, ferric sulfate, nitrate, nitric acid, hydrofluoric acid, sulfuric acid, copper sulfate, phosphoric acid, formic acid, acetic acid, etc all kinds of acid corrosion,
    Widely used in chemical, food, medicine, papermaking, oil and atomic uns c68700 energy industry, and construction, kitchenware, tableware, automobile, household appliances all kinds of spare parts.
    Deposited on the surface of the stainless steel contain other metal elements of attachments, or heterogeneous metal particles of dust in the humid air, attachments and stainless steel, the condensed water between the both together as a micro battery, triggers the electrochemical reaction, protective film is damaged, to call the electrochemical corrosion.
    Stainless steel surface adhesion organic fluids (such as melon uns c70600 seeds, noodle soup, sputum, etc.), under the condition of water is oxygen, organic acid, organic acid to for a long time and are on the surface of the metal corrosion.
    Stainless steel surface adhesion containing acid, alkali, salt substances (e.g., decorate the walls of caustic soda and lime water splash), cause local corrosion.
    In pollution in the air (e.g., contains a lot of sulfur, carbon oxide, atmospheric nitrous oxide), in the condensation water, formation of sulfuric acid, nitric acid, acetic acid, liquid, chemical corrosion.
    The above situation can be caused by the destruction of the stainless steel surface protective film cause corrosion.
