Detailed introduction of stainless steel plate

Stainless steel medium plate refers to the steel plate with thickness of 4-25.0mm, the plate with thickness of 25.0-100.0mm is called thick plate, and the plate with thickness of more than 100.0mm is called extra thick plate.

1、 Austenitic stainless steel Austenitic stainless steel is the most important type of stainless steel, and its output and consumption account for 70% of the total amount of stainless steel. According to the alloying method, austenitic stainless steel can be divided into two categories: chromium-nickel steel and iron-chromium-manganese steel. The former takes nickel as the austenitizing element and is the main body of austenitic steel; The latter is a nickel-saving steel with manganese and nitrogen instead of expensive nickel. Generally speaking, austenitic steel has good corrosion resistance, good comprehensive mechanical properties and technological properties, but low strength and hardness.

2、 Ferritic stainless steel Ferritic stainless steel contains 11% - 30% chromium, and basically contains no nickel. It is a nickel-saving steel, and its structure is mainly ferrite under use. Ferritic stainless steel has high strength, low tendency of cold work hardening, excellent resistance to chloride stress corrosion, pitting corrosion, crevice corrosion and other local corrosion, but is sensitive to intergranular corrosion, and low temperature toughness.

3、 Duplex stainless steel is generally considered as austenitic+ferritic duplex stainless steel if there is more than 15% ferrite on the austenitic matrix or more than 15% austenite on the ferrite matrix. Duplex stainless steel has the advantages of both austenitic and ferritic steels.

4、 Martensitic stainless steel Martensitic stainless steel is a kind of steel whose properties can be adjusted by heat treatment, and its strength and hardness are high.

5、 Precipitation-hardening stainless steel Precipitation-hardening stainless steel is a kind of steel that precipitates carbides in steel by means of heat treatment to improve strength.

It is widely used to make various kinds of containers, furnace shells, furnace plates, bridge and automobile static steel plates, low alloy steel plates, bridge steel plates, general steel plates, boiler steel plates, pressure vessel steel plates, checkered steel plates, and automobile girder steel plates. Some parts and welding components of tractor. As a high-quality product, stainless steel is mainly used in the following fields: 1 In terms of kitchen appliances, there are mainly overall facilities such as sinks, shelves and cabinets. 2. In the field of transportation, it is applied to the exhaust system, bumper and exterior decoration of railway vehicles and automobiles. This alone has a global demand of 2 million tons. 3. The construction industry is also a major consumer of stainless steel pipes. It is applied to the roof, interior and exterior decoration of buildings, stairs, guardrails and protective nets for home use, and then replaces carbon steel, with more aesthetic performance. 4. It has excellent performance that many other metals do not have. It has excellent corrosion resistance and recyclable performance. From aviation to navigation, from family to factory, the charm of stainless steel is fully displayed. With the deepening of people's understanding of stainless steel pipe, its practical scope will be more extensive.
