Stainless steel is the abbreviation of stainless acid-resistant steel, which is resistant to weak corrosive media such as air, steam, and water, or has stainless properties in the medium. The main types of stainless steels include ferritic stainless steels, austenitic stainless steels, austenitic-ferritic duplex stainless steels, martensitic stainless steels, and precipitation-hardening stainless steels, among others. And stainless steelIt is a German grade of stainless steel material, which belongs to martensitic stainless steel.
1.Technical parameters
Stainless steelThe technical parameters include chemical composition, mechanical properties and heat treatment regime.
Chemical composition: The material contains high chromium and nickel elements, as well as small amounts of silicon, manganese, phosphorus, sulfur and other elements.
Mechanical properties: stainless steelIt has good strength and hardness, and has good plasticity and toughness. Its tensile strength can reach more than 1000MPa, and the yield strength is also high.
Heat treatment system: The material can adjust its mechanical properties through heat treatment, and the commonly used heat treatment system includes solution treatment and aging treatment.
2.Performance characteristics:
Stainless steel 1The 4841 has the following performance characteristics:
Corrosion resistance: The material contains a high chromium element and has good corrosion resistance. At room temperature, stainless steelIt is not easy to be corroded by atmosphere, water and some acids, alkalis, salts and other media.
High strength: The material has high strength and hardness, and can withstand large pressures and loads.
Good plasticity: The material has good plasticity and can be deformed by cold working to manufacture parts of various shapes.
Good toughness: The material has good toughness, is not easy to brittle, and can be used at low temperatures.
Good weldability: The material has good welding properties and can be welded by various welding methods.
In addition, stainless steelIt also has good heat resistance and low temperature resistance, and can be used for a long time in high and low temperature environments. At the same time, the material also has good processing properties and can be used for cutting, bending, stamping, forging and other processing operations.
