The difference between cast iron platform and cast steel platform

Although both cast iron platforms and cast steel platforms are iron carbon alloys, they have different metallographic structures after crystallization due to the different percentages of chemical elements such as carbon, silicon, manganese, phosphorus, and sulfur, resulting in many differences in mechanical and process properties. For example, in the cast state, the elongation, cross-sectional shrinkage, and impact toughness of cast iron are lower than those of cast steel; The compressive strength and shock absorption performance of cast iron are better than those of cast steel; Gray cast iron has better liquid flowability than cast steel and is suitable for casting thin-walled castings with complex structures; During the bending test, cast iron exhibits brittle fracture, while cast steel undergoes bending deformation. Wait a moment.

Cast iron platform: wear-resistant, material requirements GAOQIANGDU cast iron HT200-300, hardness HB170-240, annealed at 600-700 degrees Celsius in a tempering kiln for aging treatment. But it has low strength, poor plasticity and toughness, and poor weldability.

The annual production of cast iron is generally 1/10~1/7 of the steel production, and the tensile strength of cast iron is more than 10 times higher than the initial 80 megapascals.

Steel casting platform: Currently, the production of steel castings in some industries accounts for about 2% of the total steel production, and manufacturing sectors such as railways, construction, metallurgical machinery, heavy machinery, and ships are industries that use steel castings more frequently. There are defects such as porosity, segregation, shrinkage, bubbles, inclusions, and coarse grains in cast steel. These defects cannot be welded or refined during the rolling process like deformed steel, nor can they be improved by cold processing. Therefore, its mechanical properties (mainly plastic toughness) are generally lower than rolled materials of the same steel grade. The larger the component, the greater the difference. As for NAIMOXING, weldability, and machinability, there is no significant difference from rolled materials.

The performance of cast steel platform is significantly better than that of cast iron platform, and it can be welded, but the cost is higher than that of cast iron parts.
