316 stainless steel pipe manufacturers, 316 stainless steel pipe, stainless steel Chi Yu

Texture: the surface mesh ingot projections called moire. Pits: ingot surface pits exist is called pits. Double casting: ingot surface four weeks visible signs of reclosing flash: the existence of the head or tail of ingot steel ingot perpendicular to the surface of the metal sheet called flash. Fin: vertical surface of the ingot in sheet ingot surface is called the fin. Surface inclusions: is embedded in the ingot surface decreases in the non-visible inclusions. Surface porosity: refers to the ingot surface is exposed to visible small holes, more common in the lower part of the steel ingot, usually not deep, you can finish the removal. Burst: ingot surface cracks generated when cold, because often mixed with the sound of cracking, so called burst. Rose: ingot head irregular bumps, which defect called up, also called to take up. Bubble: Bubble is due to poor degassing of molten steel deoxidation or injection systems raw steel wet ingot or other reasons caused by defects earlier, it normally skin bubbles and bubbles inside. (Prevention method: boiling molten steel oxidation reduction deoxy be good chat and everything furnace refractories in contact with molten steel to be dried, a steel tank, buns, hand, mold, etc. should be dry, the mold should be cleaned of rust, thinner were oiled. ) Stainless steel is extremely thin and fine solid stable chromium-rich oxide film (protective film) formed by the surface, to prevent the continued infiltration of oxygen atoms, to oxidation, to obtain resistance to rust. If there is some reason, this film was constantly undermined, air or liquid oxygen atoms will continue to infiltrate or metal from iron atoms constantly analyze it, to form a loose iron oxide, metal surface rust will continue to suffer. This form of surface film damaged many everyday common are the following categories: 1. attachments with stainless steel surface accumulating dust containing other metal elements or heterogeneous metal particles, in the humid air, attachments stainless steel and condensate between the two together into a micro-battery, causing the electrochemical reaction, the destruction of the protective film 316 stainless steel tube, called a electrochemical corrosion. 2. Stainless steel surface adhesion of organic juice (such as vegetables, soup, sputum, etc.), in the case of water oxygen to form organic acids 316 stainless steel pipe supplier for a long time the organic acids on corrosion of metal surfaces. 3. Stainless steel surface adhesion containing acid, alkali, salts (such as wall decoration alkaline, lime splash) 316 stainless steel pipe distributors, causing localized corrosion. 4. In the air pollution (such as those containing sulfides, carbon dioxide, nitrogen oxide atmosphere) 316 stainless steel pipe distributors, case of condensation water to form sulfuric acid, nitric acid, acetic acid solution point, causing chemical corrosion. 316 stainless steel pipe manufacturers, 316 stainless steel pipe, stainless steel supplied by Chi Yu, Foshan City, Chi Yu Stainless Steel Materials Co..
