Ferritic and martensitic stainless steels are represented by series numbers. Ferritic stainless steel is marked with and martensitic stainless steel is marked with and C, stainless steel pipe and ferritic stainless steel according to the matrix structure. Chromium content % ~ %. Its corrosion resistance,Steel etching belt and its chloride stress corrosion resistance is better than other kinds of stainless steel.iauliai International Airport , stainless steel stretching belt, stainless steel polishing belt, stainless steel soft belt,iauliai International Airport Stainless steel connecting pipe, stainless steel hard belt, stainless steel medium hard belt, stainless steel high temperature resistant belt, etc.The slab solidified on the surface continues to be rapidly cooled through the secondary cooling section until the core becomes solid, and the whole continuous casting process of stainless steel pipe fittings is completed.Heilbron, workbench, utensils and medical instruments in the food industry The demand for tableware, towel hanging bracket and bracket of refrigerator in daily life is increasing.The corrosion resistance is the same, and the strength is better because the carbon content is relatively high.Model & mdash; After that, the second widely used steel is mainly used in food industry and surgical equipment. Molybdenum is added to obtain a special corrosion-resistant structure. Because it has better chloride corrosion resistance than it, it is also made & ldquo; Marine Steel & rdquo; To use. SS is usually used in nuclear fuel recovery units. Grade stainless steel generally meets this application grade.

AUSTENITIC FERRITIC duplex stainless steel. It has the advantages of both austenitic and ferritic stainless steel, and has superplasticity. Martensitic stainless steel. High strength, but poor plasticity and weldability.However, some people will still communicate online or by telephone to ask whether the stainless steel pipe we produce can be used as a water pipe.No solution treatment. The alloy elements do not dissolve into the matrix, resulting in low alloy content and poor corrosion resistance.Installation requirements,Stainless steel pipes are divided into ordinary carbon steel pipes, high-quality carbon structural steel pipes, alloy structural pipes, alloy steel pipes, bearing steel pipes,iauliai International Airport Stainless steel decorative pipe 201, stainless steel pipes, bimetallic composite pipes coated and coated pipes to save precious metals and meet special requirements. Stainless steel pipes have a wide variety, different uses, different technical requirements and different production. The outer diameter range of steel pipe currently produced is . & mdash; mm, wall thickness range . ~ mm. In order to distinguish its characteristics, we specialize in providing quality assurance for L stainless steel pipe, s stainless steel pipe and L stainless steel pipe. During the preferential activities, new and old customers are welcome to consult. Steel pipes are usually classified according to the following.At present, stainless steel backing is divided into two processes: back argon filling and non argon filling. Back argon filling protection can be divided into solid wire + TIG process and solid wire + TIG + water-soluble paper process; The back non argon filling protection is also divided into flux cored wire backing welding and welding rod (flux coated wire) backing TIG welding.The main way to prevent stress corrosion of austenitic stainless steel is to add SI ~ % and keep the content of N below .% from smelting. In addition, the content of impurities such as P, Sb, Bi and as should be reduced as much as possible. In addition, A-F dual phase steel can be selected, which does not correspond to stress corrosion in Cl - and oh - media. The initial micro crack will not continue to expand after encountering ferrite phase, and the ferrite content should be about % .

Human factors are also one of the causes of product oxidation that some consumers often encounter when using stainless steel products. Some consumers operate improperly in product use and maintenance, especially some stainless steel pipe products used in food and chemical equipment industry. For the artificially generated oxidation of steel products, they should have correct product use knowledge and Reasonable and effective maintenance shall be carried out regularly to reduce oxidation caused by improper use.Installation requirements,Stress corrosion cracking (SCC) refers to the cracking caused by the combined action of stress corrosion stress (mainly tensile stress) and corrosion of austenitic stainless steel Austenitic stainless steel is prone to stress corrosion in corrosive media containing chloride ions. When the Ni content reaches % - %, it is a long-term enterprise engaged in stainless steel plate, stainless steel coil, stainless steel belt and stainless steel pipe. Welcome to consult. The stress corrosion tendency of austenitic stainless steel is very large. Continue to increase the Ni content to ~ % and the stress corrosion tendency gradually decreases until it disappears.The cold working process performance and cold forming performance are much better than that of ferritic stainless steel.Stainless steel tube for boiler tube and heat exchanger (gjb- (yb-) aviation structural tube, thick wall seamless steel tube (gjb- (yb-) aviation stainless steel tube (ybt-) (yb-) aviation a blind rivet seamless steel tube (gjb- (yb-) aviation structural tube, Ferritic and austenitic alloy steel pipe) General requirements General requirements for ferrous and alloy steels for special purposes General requirements for carboniauliai International Airport ,Flux coated welding wire (self shielded welding wire) shall be used for backing TIG welding.First of all, let's understand what stainless steel is. Generally speaking, steel that will not rust is called stainless steel, but in an academic sense, steel resistant to weak corrosive media such as air, steam and water and chemical corrosive media such as acid, alkali and salt. Also known as stainless acid resistant steel. In practical application, the steel resistant to weak corrosion medium is often called stainless steel, while the steel resistant to chemical medium is called acid resistant steel. Due to the difference in chemical composition between the two, the former is not necessarily resistant to chemical medium corrosion, while the latter is generally stainless. The corrosion resistance of stainless steel depends on the alloying elements contained in the steel. Chromium is the basic element for stainless steel to obtain corrosion resistance. When the chromium content in the steel reaches about %, chromium reacts with oxygen in the corrosive medium to form a thin oxide film (self passivation film) on the steel surface, which can prevent further corrosion of the steel matrix. In addition to chromium, the commonly used alloy elements include nickel, molybdenum, niobium, copper, nitrogen, etc., so as to meet the requirements of various uses on the microstructure and properties of stainless steel.. Raw material problem of stainless steel pipe. If the hardness is too low, it is not easy to polish (BQ is not good). If the hardness is too low, orange peel is easy to appear on the surface during deep drawing, which affects BQ performance. BQ with high hardness is relatively good.
