Adjust the ratio of austenite forming elements to ferrite forming elements in the steel to make it have austenite + ferrite dual phase structure in which ferrite accounts for % - %. This dual phase structure is not easy to produce intergranular corrosion.In engineering, that is, fundamentally solve the problem of precipitation of chromium carbide (crc) on the grain boundary. Generally, the requirement of intergranular corrosion resistance can be met when the amount of carbon in steel is reduced to less than .%.Tepik,Spcespce & mdash; & mdash; refers to cold-rolled carbon steel sheet and strip for deep drawing, equivalent to China Al () deep drawing steel. If it is necessary to ensure non aging property add n at the end of the brand as spcen. Quenching and tempering code of cold-rolled carbon steel sheet and strip: annealing status is a, hard is / / hard is / standard quenching and tempering is s, hard is . Surface processing code: dull finish rolling is D, bright finish rolling is B. spcc-sd represents cold-rolled carbon sheet generally used for standard quenching and tempering and matt finish rolling. Another example is spcct-sb It refers to cold-rolled carbon sheet with standard quenching and tempering and bright processing and required to ensure mechanical properties.Bidirectional Product Description: the tensile strength of the material is ~ mpa, and the high working temperature can reach ℃.Tartous,TepikStainless steel connecting pipe,CE--“ Code for design of cold formed stainless steel structural parts & rdquo; And & ldquo; jointly published by nidi and euro inox; Structural stainless steel design manual & rdquo; The design of structural parts for buildings with long service life and good integrity has been simplified.Model & mdash; The addition of sulfur improves the processability of the material.Model & mdash; Cheap model (British and American), usually used as automobile exhaust pipe, is ferritic stainless steel (chromium steel).

Model & mdash; Martensite (high strength chromium steel), good wear resistance and poor corrosion resistance.Delivery status: to be delivered after heat treatment and leveling.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, 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 titanium, niobium, copper, nitrogen, etc., so as to meet the requirements of various uses on the microstructure and properties of stainless steel.recommend,During welding, the process of ventilation in advance and gas stop behind shall be adopted, and the adhesive cloth on the outside shall be torn off while welding. Because the blocking plate is composed of rubber and white iron sheet, it is not easy to be damaged, so this welding can well ensure that the inner side of the weld is filled with argon and its purity, so as to effectively ensure that the metal on the inner side of the weld is not oxidized and ensure the quality of weld backing welding.With the implementation of China's reform and opening up, the national economy has achieved rapid growth, and a large number of urban houses, public buildings and tourism facilities have been built, which puts forward new requirements for hot water supply and domestic water supply. In particular, people pay more and more attention to the problem of water quality, and the requirements are also increasing. Galvanized steel pipe, will gradually withdraw from the historical stage under the influence of relevant countries because of its corrosivity. Plastic pipe, composite pipe and copper pipe have become common pipes in the pipeline system. However, under certain circumstances, stainless steel pipe has more advantages,TepikStainless steel pipe 201, hot water system and water supply system that puts safety and sanitation first, it has the characteristics of safety, reliability, sanitation,TepikArgon arc welding of thin stainless steel pipe, environmental protection, economy and applicability. It has been proved by engineering practice at home and abroad that it is one of the new, energy-saving and environmental protection pipes with good comprehensive performance of water supply system. It is also a very competitive water supply pipe, which will play an incomparable role in improving water quality and people's living standards.Model & mdash; Add a small amount of sulfur and phosphorus to make it easier to cut.

. It is our responsibility not to pay attention to the maintenance of the pipe during transportation, or soak the two water into the packaging film during transportation in rainy days, which will cause rust. . It is the responsibility of the processor and manufacturer. When cutting stainless steel or iron when manufacturing goods, the scrap iron will cause rust on the surface of the steel pipe. Therefore, it is only reasonable for highly skilled technicians to deepen investigation and discussion, make a reasonable division of responsibilities, and who should be responsible for whose achievements. You can't let steel mills, pipe factories, processors, or users bear the liability for compensation!Quality documents,Model & mdash; Except that the risk of weld corrosion of the material is reduced due to the addition of titanium, other properties are similar. Stainless steel decorative pipe, stainless steel pipe, series stainless steel pipe & mdash; Ferritic and martensitic stainless steel model & mdash; Good heat resistance, weak corrosion resistance, % Ni.For the length of welding arc, ~ mm is better for ordinary steel welding, and ~ mm is better for stainless steel welding. If it is too long, the protection effect is not good.Stainless steel has two classifications: one is divided into chromium stainless steel and chromium nickel stainless steel according to the characteristics of alloy elements; The other is divided into m stainless steel, f stainless steel, a stainless steel and A-F duplex stainless steel according to the microstructure of steel in normalized state.Tepik,Austenitic stainless steel austenitic stainless steel is developed to overcome the lack of corrosion resistance and brittleness of martensitic stainless steel. The basic composition is crl% and Ni%, which is referred to as - steel for short. Its characteristic is that the carbon content is less than .%, and the single-phase austenite structure is obtained by the combination of Cr and Ni.Because stainless steel has many ideal properties required by building materials, it can be said to be unique in metals, and its development continues. In order to make stainless steel more neutral in traditional applications, existing types have been improved, and new stainless steel is being developed to meet the strict requirements of advanced architectural applications. Due to the continuous improvement of production efficiency and quality, stainless steel has become one of the cost-effective materials selected by architects. Stainless steel integrates performance, appearance and use characteristics, so stainless steel will still be one of the best building materials in the world.Stainless steel why corrosion-resistant stainless steel decorative pipe, stainless steel pipe, stainless steel pipe, all metals react with oxygen in the atmosphere to form an oxide film on the surface. Unfortunately, the iron oxide formed on ordinary carbon steel continues to oxidize, expanding the corrosion and finally forming holes. The carbon steel surface can be guaranteed by electroplating with paint or oxidation resistant metals (e.g. zinc, nickel and chromium), but as is known, this protection is only a thin film. If the protective layer is, the steel below begins to rust.
