Carbon steel casting
Steel castings with carbon as the main alloying element and containing a small amount of other elements. Low carbon steel castings contain less than 0.2% carbon, medium carbon steel castings contain 0.2% to 0.5% carbon, and high carbon steel castings contain more than 0.5% carbon. As the carbon content in steel castings increases, the strength and hardness of steel castings increase. Due to its advantages of high strength, plasticity and toughness, and low cost, many parts used in heavy machinery to bear heavy loads are carbon steel castings.
Carbon steel casting features
1. High strength: Steel castings are much stronger than other types of steel, which gives them an advantage in applications that are subject to heavy loads and high stresses. The tensile strength of steel castings can reach 1200 MPa, while the tensile strength of ordinary carbon steel is only 375 MPa.
2.Good toughness: Steel castings have good toughness and can maintain high resistance to deformation even when subjected to impact loads. This makes steel castings advantageous in applications subject to vibration and shock.
3.High wear resistance: Steel castings have a high surface hardness and therefore have good wear resistance. This makes steel castings advantageous in applications subject to wear and friction.
4.Good casting performance: Steel castings have good casting performance, and can be used to produce parts with complex shapes and large sizes through the casting process. This makes steel castings advantageous in the manufacture of large and complex mechanical parts.
5.Low production cost: Compared with other types of steel, the production cost of steel castings is low. This is because the production process of steel castings is relatively simple and does not require complex processing and heat treatment.
6.Good cutting performance: Steel castings have good cutting performance and can be used to produce parts with high precision. This gives steel castings an advantage in manufacturing high-precision parts.
