The standard of stainless steel can vary according to different countries and regions. Here are some common criteria:
European Standards: 14462 is generally regulated in Europe in accordance with EN 10088, which includes parts EN 10088-1 (stainless steel - general technical terms of delivery), EN 10088-2 (stainless steel - technical terms of delivery, available for cold working) and EN 10088-3 (stainless steel - technical terms of delivery, can be heat-processed).
U.S. Standards: Commonly used standards in the U.S. include ASTM A240 (Standard Specification for Chromium and Chromium-Nickel Stainless Steel Plate, Sheet, and Strip), ASTM A276 (Standard Specification for Stainless Steel and Hot Worked, Cold Worked, and Stranded Wire), ASTM A790 (Standard Specification for Chromium, Nickel, and Molybdenum Ferritic-Austenitic Duplex Stainless Steel Seamless and Welded Steel Pipe), etc.
International standards: Standards such as ISO 15156 (Material Selection and Corrosion Resistance in the Oil and Gas Industry) and ISO 9445 (Technical Conditions of Delivery for Stainless Steel Strip and Sheet Materials) also address 1Specification of 4462 stainless steel.
Mechanical properties: 1It has excellent tensile strength and is suitable for engineering applications requiring high strength. 2.It has good yield strength and shows the ability to maintain shape stability under a certain load. 3.Exhibits a high elongation, making it more flexible during processing and molding. 4.It has moderate hardness, which not only ensures strength but also has a certain processing plasticity.
Physical Properties:1The density is about 78 grams cubic centimeter, 2In the temperature range, 1The coefficient of thermal expansion of 4462 is about 137 x 10^-6 /℃。 3.The thermal conductivity is relatively low, and the thermal conductivity is relatively poor, with a thermal conductivity of about 135 w/(m·k)。This also makes it potentially limited in applications with high temperature or high thermal conduction requirements. 4.It is a duplex stainless steel, and below the solution temperature, it is non-magnetic. However, at low temperatures or after undergoing cold working, it may show a slight magnetic properties.
Chemical Composition:- Carbon(c):003 Max - Silicon (Si): 10 max - manganese (mn): 20 max - phosphorus (p): 003 Max - Sulfur (s): 002 max - chromium (cr): 210-23.0 - Nickel (Ni): 45-6.5-Molybdenum (Mo): 25-3.5-Nitrogen (n): 008-0.2 It also contains a certain amount of copper (Cu) and a residual amount of iron (Fe).
This chemical composition makes 14462 has a duplex structure with both ferrite and austenite characteristics. This structure gives this stainless steel good corrosion resistance, strength and toughness. 1.The chemical composition of 4462 gives it good corrosion resistance and excellent performance in some corrosive environments, making it one of the widely used materials in chemical, offshore, and other applications that require corrosion resistance. In specific applications, it should be used according to the actual needs with reference to relevant standards and requirements.
