Home » Carbon Steel Casting


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.

1020 suitable for surface hardening,
high carbon steel, hardened, and welded
hydraulic shafts, motor shafts, pump shafts, machinery parts
1030high carbon steel, has moderate hardness and strength, machineable, ductilemachinery parts, used in the tempered and quenched condition for strength
1035low carbon steel, suitable for induction hardening and flameused for forged parts, links, gears, couplings, forged shafts and axles
1040has good strength, wear resistance, high carbon steel forged couplings and crankshafts
1045low carbon steel, can be forged satisfactorily, most common shafting steelinduction hardening applications, medium strength parts, shafts for pneumatic and hydraulic cylinders
1050high carbon steel, readily welded and machinedforged shafts and gears
1060standard grade carbon steelused for forged applications
1065high carbon steel, has high tensile strength, heat treatableblades and cutlery
1144low carbon steel, a higher-strength alloy than A36 and 1018, has improved ductilityused for parts requiring mechanical properties obtained by heat treating
11L14high carbon steel, has enhanced machinability, stronger than 1018used for forged applications
12L14high carbon steel, has enhanced machinability, stronger than 1018screw machines, couplings, inserts, bushings, and hydraulic hose fittings


Carbon Steel Casting Process


Carbon Steel Investment Casting

In recent years, we have undergone comprehensive updates and upgrades, completely shifting towards advanced silica sol shell making technology. We have also introduced an innovative process that combines coated sand with shell making, further optimizing the shell making process to ensure that our products can meet the highest quality standards.


Carbon Steel Sand Casting

In the sand casting process, different foundries choose various sand mold materials based on customer performance requirements, such as silica sand, resin sand, pearl sand, expanded sand, etc. Dawang mainly uses resin sand and pearl sand, which are famous for their uniform particles and good fire resistance, suitable for high-temperature and high demand casting scenarios.


Carbon Steel Shell Casting

The shell casting production line in Dawang has achieved comprehensive automation, aiming to ensure production efficiency and product quality. Our monthly production capacity is up to 800 tons, capable of producing stainless steel castings weighing up to 200 kilograms, providing customers with stable and reliable supply.

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).
