medium carbon steel sheet
medium carbon steel sheet
Medium carbon steel sheet contains approximately 0.3% to 0.6% carbon, achieving a good balance between strength, hardness, and ductility. Compared to low-carbon steel, it offers higher strength and wear resistance, while providing better cost efficiency than alloy steel. It is well-suited for heat treatment and machining.
Common applications include components requiring moderate strength and durability, such as gears, shafts, automotive parts, and structural machinery.
Zhaojian Steel offers a range of medium carbon steel grades, including 1040, 1045, 1050, and 1055, available in both hot-rolled and cold-rolled forms to meet diverse processing and application needs.

Medium Carbon Steel Sheet Manufacturing Process
Rolling and Forming
Steel billets are processed into sheets by:
Hot Rolling – Heated billets are rolled into thick sheets with high efficiency and a slightly rough surface.
Cold Rolling – Hot-rolled sheets are further compressed at room temperature for better precision and surface finish.
Optional Surface Treatments
Pickling + Oiling – Removes scale and prevents rust.
Shot Blasting – Prepares surface for coating.
Skin Pass – Improves surface appearance.
Heat Treatment Options
Normalizing – Refines grain and relieves stress, improving structural reliability.
Annealing – Softens cold-rolled sheets for easier forming or stamping.
Quenching & Tempering (Q&T) – Increases hardness and strength for high-load parts like gears or dies.
FAQ
Medium carbon steel sheet itself has limited corrosion resistance and typically requires coatings, galvanization, or other surface treatments to improve durability.
Yes, the thickness, width, length, and surface treatment of medium carbon steel sheets can all be customized according to customer requirements.
