With the development of society, more and more people use medium and heavy plates. In all walks of life, the figure of stainless steel plate can be seen. Therefore, the development prospect of stainless steel plate is immeasurable. The basic characteristics of stainless steel plate are introduced below. The characteristics of stainless steel medium and thick plates: 1. Austenitic stainless steel in 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 way of alloying, austenitic stainless steel can be divided into chromium nickel steel and iron chromium manganese steel two categories. The former uses nickel as an austenitic element and is the main body of austenitic steel, and 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 the strength and hardness are low. 2, ferritic stainless steel ferritic stainless steel with chromium 11%-30%, basically no nickel, is a nickel steel, in the state of use, the structure of the ferrite mainly. Ferritic stainless steel has higher strength and cold working hardening tendency, but it has good local corrosion resistance to chloride stress corrosion, pitting corrosion and crevice corrosion. But it is sensitive to intergranular corrosion and low temperature toughness. 3, it is generally believed that 15% or more ferrite on the austenite matrix or 15% austenite on ferrite substrate can be called austenite + ferrite duplex stainless steel. The dual phase stainless steel has the advantages of both austenitic and ferritic steel. 4. Martensitic stainless steel martensitic stainless steel is a kind of steel which can adjust its properties by heat treatment. Its strength and hardness are high. 5. Precipitated hardened stainless steel precipitated and hardened stainless steel can precipitate carbides in steel by heat treatment, thus achieving the purpose of improving the strength of steel.
