 [1] according to the organizational characteristics of the steel is divided into five categories: austenitic, austenitic - ferritic, ferritic, martensitic, precipitation hardening. 

 To withstand all kinds of acid corrosion of oxalic acid, sulfuric acid - ferric sulfate, nitric acid, nitric acid - hydrofluoric acid, sulfuric acid - copper sulphate, phosphoric acid, formic acid, acetic acid, widely used in chemical, food, pharmaceutical, paper, oil, atomic energy, etc. industrial, and construction, kitchen utensils, cutlery, vehicles, household appliances, all kinds of parts. 

 Meet the requirements in order to ensure the mechanical properties of yield strength, tensile strength, elongation and hardness of various types of stainless steel plate, steel plate prior to delivery must be after annealing, solution treatment, aging treatment and other heat treatment. 

 Stainless steel plate, smooth surface, high ductility, toughness and mechanical strength, acid, alkaline gas, solution and other media corrosion. It is an easy-to-rust alloy steel, but not absolute does not rust. 

 Stainless steel corrosion resistance depends mainly on the alloy composition (chromium, nickel, titanium, silicon, aluminum, etc.) and the internal organizational structure, play a major role of chromium. Chromium has a high chemical stability, the steel surface to form a passive film, the metal and the outside world to isolate and protect the steel plate is not oxidized, and to increase the corrosion resistance of steel plate. After the destruction of the passive film, corrosion resistance decreased. 

 Characteristics and uses of stainless steel: 


 Grade characteristics and uses of the serial number category 


 An austenitic the shape 1Cr17Mn6Ni5N section nickel steels instead of grades 1Cr17Ni7 with magnetic after cold working. Railway rolling stock. 


 2 1Cr18Mn8Ni5N section of nickel steel, instead of grades 1Cr18Ni9 


 3 the 1Cr17Ni7 by cold high strength. Railroad cars, conveyors, bolts and nuts 


 4 1Cr18Ni9 by cold high strength, but elongation is somewhat less than 1Cr17Ni7. Building with decorative parts. 


 5 Y1Cr18Ni9 improve the cutting resistance, ablative. Most suitable for automatic lathes. Bolts and nuts 


 6 Y1Cr18Ni9Se improve cutting resistant ablative. Most suitable for automatic lathes. Rivets, screws 


 7 of 0Cr19Ni9 as the most widely used heat-resistant stainless steel, food equipment, general chemical equipment, nuclear power industries 


 Lower the 8 00Cr19Ni11 the 0Cr19Ni9 carbon content steel, intergranular corrosion resistance superior for welding without heat treatment component class 


 N 0Cr19Ni9N in grades 0Cr19Ni9 strength increases, the plastic does not reduce. Reduce the thickness of the material. As a structure with the strength of parts 


 10 0Cr19Ni10NbN in grades 0Cr19Ni9 on the N and Nb, with the same characteristics and uses and 0Cr19Ni9N 


 The 11 00Cr18Ni10N on the grades 00Cr19Ni11 N, has the same characteristics of the above grades for use with 0Cr19Ni9N the same, but better resistance to intergranular corrosion 


 12 1Cr18Ni12 and 0Cr19Ni9 compared to hardening. Spinning, special drawing, cold heading 


 13 0Cr23Ni13 corrosion resistance, heat resistance than 0Cr19Ni9 


 The 14 0Cr25Ni20 engage in oxidizing than 0Cr23Ni13 good. In fact, mostly as heat-resisting steel 


 15 0Cr17Ni12Mo2 in sea water and various other media, corrosion resistance than 0Cr19Ni9. Mainly for the resistance to pitting corrosion materials 


 0Cr18Ni12Mo2Ti used for resistance to sulfuric acid, phosphoric acid, formic acid, acetic acid equipment, good resistance to intergranular corrosion 


 Of 17 00Cr17Ni14Mo2 for 0Cr17Ni12Mo2 ultra-low carbon steel to intergranular corrosion resistance than the 0Cr17Ni12Mo2 


 18 0Cr17Ni12Mo2N in grades 0Cr17Ni12Mo2 in N, increase strength, lower ductility, the material thickness decreases. For resistance to the good corrosion of high strength parts 


 The 19 00Cr17Ni13Mo2N in grades 00Cr17Ni14Mo2, joined N, has the same characteristics of the above grades for use with 0Cr17Ni12Mo2 the same, but better crystalline corrosion resistance 


 20 0Cr18Ni12Mo2Cu2 resistant to corrosion, resistance to pitting corrosion than 0Cr17Ni12Mo2. For resistance to sulfuric acid material 


 Of 21 00Cr18Ni14Mo2Cu2 for 0Cr18Ni12Mo2Cu2 ultra-low carbon steel to intergranular corrosion resistance than the 0Cr18Ni12Mo2Cu2 


 22 0C19Ni13Mo3 resistance to pitting corrosion than 0Cr17Ni12Mo2. For dyeing equipment and materials 


 23 00Cr19Ni13Mo3 for 0Cr19Ni13Mo3 of ultra-low carbon steel to intergranular corrosion resistance than the 0Cr19Ni13Mo3 


 24 0Cr18Ni16Mo5 draw the chlorine ion solution heat exchangers, equipment, acetate, phosphate equipment, bleaching devices in the 00Cr17Ni14Mo2, and 00Cr17Ni13Mo3 not applicable environmental 


 1Cr18Ni9Ti for welding equipment and spare parts of plantago, the diamagnetic instrumentation, medical equipment, acid-resistant containers and equipment lining pipeline 


 0Cr18Ni11Ti add Ti improve the resistance to intergranular corrosion is not recommended for decorative parts 


 27 0Cr18Ni11Nb of Nb to improve the resistance to intergranular corrosion 
 The success of the Corporation, the combination of hard work and wisdom of all employees of the company, but also embodied the love and affection of the vast number of consumers, but also inspired the courage to fight the conviction of all employees of the company, we will continue to achieve a new leap forward to create enterprises greater glory for the the development of Tianjin to make a contribution.
