Carbon steel casting mainly uses carbon steel, a type of steel with a carbon content ranging between 0.02% and 2%, and minimal presence of other elements, for making the metal part. From industrial machinery to automotive parts, carbon steel castings offered by leading manufacturers, showcase adaptability across diverse sectors.

Carbon steel stands as the most widely produced metal material. The higher the carbon content, the greater the hardness, strength, and wear resistance after heat treatment, but also the brittleness. As dedicated carbon steel casting manufacturers, our stringent quality controls guarantee industry-standard excellence in every casting.

FAQ

What's The Difference Between Carbon Steel And Cast Iron?

Carbon steel is an iron – carbon alloy with a carbon content of 0.0218% to 2.11%. Cast iron generally has a carbon content of 2.5% to 3.5%. Carbon steel castings has relatively good strength and toughness and is used to manufacture various mechanical parts and metal products. The properties of cast iron are lower than steel, especially the tensile strength and plasticity are low, and it cannot be forged, but its hardness and compressive strength are better.

Mild Steel Casting In Carbon Steel Products

Mild steel refers to steel with 0.15 to 0.25 percent carbon and not many additional alloying components. Mild steel and low-carbon steel are both iron-based metals. Mild steel contains higher amounts of carbon than low-carbon steel. More than half of the common carbon steel products are mild steel casting. Like some mild steel casting samples shown above, Dawang provides you with various mild steel products. Regarding mild steel cost, we will provide you with a satisfactory price. For more information, please consult our mild steel cost service.

What Are The Defects Of Carbon Steel Castings?

1. Gas Porosity

The reason for the pores is that there is too much water in the molding material or a lot of gas – producing substances; the air permeability of molding sand and core sand is poor; the pouring speed is too fast.

2. Trachoma

The causes of blisters include insufficient molding sand strength; insufficient molding sand compactness; and too fast pouring speed.

3. Shrinkage

The cause of shrinkage cavity is poor feeding of the casting during solidification.

4. Sticky sand

The cause of sticky sand is the poor fire resistance of the molding sand or the high pouring temperature.

5. Cracks

The causes of the cracks are the large difference in the wall thickness of the castings; the improper setting of the gating system; the new difference between the sand mold and the core.

How To Distinguish Carbon Steel Casting Grades?

Carbon steel casting grades are divided into three subgroups according to the carbon content of the metal: Low carbon steel castings/Mild steels (up to 0.3% carbon), Medium carbon steel castings(0.3–0.6% carbon), and High carbon steel castings (more than 0.6% carbon).
