It can be said that the key to the difference between steel and iron is reflected in the moisture content of carbon. Similarly, the difference between cast steel bearing seats and cast iron bearing seats means that the composition is different. Moreover, due to their different compositions, their own structural characteristics are also different. In general, the plastic deformation of steel also has good toughness, which means that its tensile strength and cross-sectional shrinkage have good impact rate, while the physical properties of iron are specifically hard and brittle. So how do people carry out identification in their daily lives?
1. Chroma, cast steel bearing seats will emit light, while cast iron bearings may appear darker or grayer. The gray iron in cast iron is different from that in ball mill cast iron, and ductile iron is brighter than gray iron;
2. Particles are relatively concentrated in the relative density of cast steel during forging, so inconspicuous particles are used on the surface. Gray iron and ductile iron can be seen, and the particles of gray iron are larger;
3. Noise: If the cast iron bearing seat collides, it will produce a mute sound, while if the cast steel bearing seat collides, it will produce a brittle sound. If the cast iron material is in a very good condition, the noise will be mixed;
4. Toughness, as is well known, cast steel has good toughness and is relatively close to thick steel plates. The toughness of cast iron is relatively inferior, and thick walled parts can achieve bending at 20-30 degrees, while gray edges do not have toughness;
5. Oxygen cutting, the surface of cast steel is not smooth, and the total area of the riser is also large, so oxygen cutting is carried out to eliminate it. The application of oxygen cutting in cast iron is continuous cutting.
That's all for the brief summary of the key knowledge points of cast steel bearing seats and cast iron bearing seats. If customers show the engineering drawings of the bearing seats, they can customize the production and processing of the bearing seat models, specifications, and cast steel parts for you!
