What is Carbon Steel Casting?
Carbon steel casting refers to the process of producing carbon steel castings using the casting process. Carbon steel is an iron-carbon alloy containing 0.02%-2.11% carbon, with good weldability, corrosion resistance, strength and wear resistance. It is widely used in machinery manufacturing, automobile manufacturing, petrochemical and chemical industries.
Advantages of Carbon Steel Casting
01. Low cost
02. Short production cycle
03. High strength and good toughness
04. Can withstand high pressure
05. Strong corrosion and abrasion resistance
06. High stability and safety
07. Can casting high load and complex working conditions of the components
Common Carbon Steel Casting Materials
Precision-cast in a wide range of AISI/SAE grades — each engineered for specific mechanical requirements and applications. Browse our comprehensive alloy selection below.
1018
