What is medium thick steel plate

Medium thick steel plate refers to the steel plate with a thickness of 4.5-25.0mm. Those with a thickness of 25.0-100.0mm are called thick plates. Those with a thickness of more than 100.0mm are extra thick plates.

The medium thick steel plate products are widely used in construction, shipbuilding, bridges, boilers, pressure vessels, construction machinery and other industries.

The medium thick steel plate is an indispensable steel product in the modernization of our country. It is widely used in the fields of large-diameter conveying pipe, pressure vessel, boiler, bridge, offshore platform, all kinds of ships, tank armor, vehicles, building components, machine structure, etc. The medium thick steel plate has a wide variety, wide range of use temperature requirements (- 20 ℃ - 600 ℃), and complex use environment requirements (weather resistance, corrosion resistance, etc.) High strength requirements (strength and toughness, good welding performance, etc.).

In general, the medium thick steel plate has high comprehensive mechanical properties. The requirements of mechanical properties include: strength, plasticity, hardness, impact toughness, rigidity, etc. Process performance requirements include: welding performance, hardenability, processability, weather resistance, corrosion resistance, wear resistance, fatigue resistance, high temperature characteristics, low temperature characteristics, etc.
