Physical Properties of 00Cr20Ni25Mo4.5Cu Austenitic Stainless Steel
00Cr20Ni25Mo4.5Cu austenitic stainless steel is a type of stainless steel with a high nickel content and a low carbon content. It is known for its excellent corrosion resistance and ease of fabrication. This type of steel is commonly used in a variety of industries, including the medical and aerospace industries, and is also used to make a wide range of consumer products as well.
The overall composition of 00Cr20Ni25Mo4.5Cu can be broken down into three main elements: chromium (Cr), nickel (Ni), and molybdenum (Mo). The chromium content is usually between 17 and 20%. This element is essential for the formation of a protective oxide film, known as a ‘passive film’, which helps to protect against corrosion and facilitate good weldability. The main benefits of the high chromium content of this stainless steel is its high corrosion resistance, high strength, and ductility.
The nickel content is usually between 25 and 30%. This element helps to give 00Cr20Ni25Mo4.5Cu its austenitic properties. Austenitic stainless steel is non-magnetic and has a low linear expansion coefficient. As it does not deform when exposed to heat, it is suitable for use in high temperatures and/or aggressive environments.
The molybdenum content is usually between 4.5 and 5%. This element greatly improves the overall toughness and corrosion resistance of the steel by creating an oxide slime layer on its surface. The increased toughness and corrosion resistance makes 00Cr20Ni25Mo4.5Cu a popular choice for applications involving high pressure, high temperature, and corrosive environments.
In terms of physical properties, 00Cr20Ni25Mo4.5Cu is a very strong and durable material. Its yield strength ranges from 380 to 540MPa and its tensile strength ranges from 500 to 850MPa. It also has good ductility and is highly resistant to a wide range of acids and bases, including many organic and inorganic compounds. Additionally, the material has a good resistance to oxidation, mechanical and thermal shock, and abrasion.
Other physical properties of 00Cr20Ni25Mo4.5Cu include modulus of elasticity of 183GPa, electrical resistivity of 0.72μΩ·m at 20°C, a thermal conductivity of 20W·m-1·K-1 at 100°C, expansion coefficient of 9x10-6K-1, hardness (HRB) of 94, and a melting range of 1,223-1,270°C.
Overall, 00Cr20Ni25Mo4.5Cu austenitic stainless steel is an excellent material for a variety of applications due to its combination of excellent corrosion resistance, strong physical properties, ease of fabrication, and good weldability. It is commonly used in a variety of industries, including the medical and aerospace industries, and is also used to make a wide range of consumer products as well.
