Can you distinguish between cast steel bearing blocks and cast iron bearing blocks?

　　It should be said that the key to the difference between steel and iron is reflected in the water content of carbon. Similarly, the difference between cast steel bearing blocks and cast iron bearing blocks is the difference in composition. It is also because of their different compositions that their own mechanical properties are different. Generally, steel has good plastic deformation and toughness, which means that its tensile strength and cross-sectional shrinkage as well as impact resistance are better, while iron's physical properties are specifically characterized by hardness and brittleness. So how do people identify in their daily lives?

1. Chromaticity: Cast steel bearing blocks emit light while cast iron bearings are darker or grayer. The gray iron in cast iron is different from the ball mill cast iron, and the ductile iron is brighter than the gray iron;

2. Particulate matter: Cast steel tends to have a high relative density and become more concentrated during forging, so invisible particles are used on the surface. Gray iron and ductile iron can be seen, and the particles of gray iron are larger;

3. "Noise: When a cast iron bearing block collides, it will make a dumb noise, while when a cast steel bearing block collides, it will make a brittle noise. If the cast iron material is very good, the noise will be mixed;";

4. Toughness: It is well known that cast steel has good toughness, which is relatively close to thick steel plates, while cast iron has a relatively poor toughness. Thick wall parts can achieve 20-30 degrees of bending, and gray edges have no toughness;

5. Oxygen cutting: The surface of cast steel is not smooth, and the total area of the riser also has a pouring port is large. Therefore, oxygen cutting is carried out to eliminate it. The application of oxygen cutting to cast iron is continuous.

The following is a brief summary of the key points of knowledge about cast steel bearing blocks and cast iron bearing blocks. If customers show the engineering drawings of the bearing blocks, they will be able to customize the production and processing of the desired bearing block models, specifications, and steel castings for you!
