Metallographic structure of DH40 steel plate

As a high-strength, hardness alloy structural steel, DH40 steel plate has excellent mechanical properties and processing properties, and is widely used in the manufacturing of various mechanical parts and building structures. The metallographic structure of tempered troostite or tempered martensite and the manufacturing process of high purity, uniformity and precision ensure the excellent quality and use value of DH40 steel plate.

The metallographic structure of DH40 steel plate is tempered troostite or tempered martensite. This structure has high strength and hardness, as well as certain plasticity and toughness. The metallographic structure also contains a certain amount of carbides and intermetallic compounds, which can effectively improve the wear resistance and fatigue resistance of DH40 steel plates.

The manufacturing process of DH40 steel plate is also relatively advanced, using high-temperature smelting, high-pressure rolling and fine processing. These processes ensure the purity, uniformity and precision of DH40 steel plates, making them of high quality and use value.
