Description
Technical Field
The invention relates to an economical two-phase stainless steel pipe product.
Background
With the progress of industrial technology, the requirements of various industries on metal materials are continuously increased, and low cost and high strength are the development trend of future metal materials. For example, in the fields of automobiles, aviation and the like, the requirement of light weight development requires that the material has higher strength and better plasticity, and the cost cannot be too high. In addition, in the precision electronics industry, a large number of high-strength thin strips are also needed to meet the requirement that the size of electronic products is gradually reduced.
Stainless steel is an important choice for materials in the industrial field because of having certain strength and corrosion resistance. However, the conventional austenitic stainless steels 304 and 316 have low strength and cannot well meet the requirements of high-strength materials, and the products contain high nickel content and have high cost. In addition, since the price fluctuation of Ni is large, the price fluctuation of these products is also large, which brings about a relatively large economic risk. Therefore, it is very important to develop an economical stainless steel, and to satisfy the requirement of high strength by technical means, so as to achieve the purpose of low cost and high strength.
In fact, in recent years, people use an N alloying means to obtain nickel-saving or even nickel-free austenitic stainless steel, so that the cost is greatly reduced, the strength is improved to a certain extent, and the products are widely applied to the fields of household electrical products, containers and the like. However, the N content of the currently developed nickel-saving austenitic stainless steel is usually below 0.2%, the yield strength is only about 400MPa, the tensile strength can only reach 700-800 MPa, and the strength can not completely meet the requirements of high-strength stainless steel. If the nitrogen content is increased to more than 0.4 percent, the prepared high-nitrogen stainless steel can meet the requirements of high-strength stainless steel, for example, the yield strength reaches more than 600MPa, and the tensile strength reaches more than 1000 MPa. However, the difficulty of the high-nitrogen steel in the actual industrial production process is very high, and wide high-nitrogen steel plates cannot be prepared at present. Therefore, in order to achieve high strength, temper rolling, known as hard stainless steel, is currently used, and the generation of deformed martensite is used to improve the strength of the material, with the 301 series of hard stainless steels being typical examples.
