1Cr17Ni2 mechanical properties
1.Chemical composition
The main chemical components of 1Cr17Ni2 are Cr, Ni and C. The content of Cr is between 17% and 19%, the content of Ni is between 1% and 3%, and the content of C is less than 015%γIn addition, it contains small amounts of other elements such as MN, SI, P, and S. The reasonable ratio of these elements makes 1Cr17Ni2 have good corrosion resistance and mechanical properties.
2.Physical properties
1Cr17Ni2 has good strength and toughness, good wear resistance and corrosion resistance, and has high tensile strength and tensile strength. Its density is about 793g cm, the melting point is about 1400-1450, and the coefficient of linear expansion is 162Γ10-6/βγ
3.Heat treatment process
Commonly used heat treatment processes for 1Cr17Ni2 include solution treatment, quenching and tempering. Solution treatment is the heating of stainless steel to a certain temperature and then rapid cooling to eliminate residual stresses in the material and improve strength. Quenching is the rapid cooling of the material to increase hardness and strength. Tempering is the reduction of hardness and improvement of toughness by heating the material and controlling the temperature and time.
4.* Morphology
The main forms of 1Cr17Ni2 include plates, coils, pipes, bars, wires, etc. Plates and coils are commonly used in the manufacture of pressure vessels, chemical equipment, food processing equipment, etc.;Pipes are often used to transport fluids, manufacture chemical equipment, etc.;Bars and wires are commonly used in the manufacture of mechanical parts, threaded parts, etc.
5.Fields of application
1Cr17Ni2 is widely used in chemical, petroleum, fertilizer, papermaking, food, medicine, construction and other fields. Especially in high-temperature and high-pressure environments where corrosion resistance and wear resistance are required, 1Cr17Ni2 is widely used.
Summary:1Cr17Ni2 is a high-quality stainless steel material with excellent corrosion resistance, mechanical properties and heat treatment properties. Its variety of forms and wide range of application fields make it widely used in industrial production. Through the introduction of this article, I believe readers have a deeper understanding of 1Cr17Ni2.
