Какво е 1008 Въглеродна стомана?
1008 carbon steel is a low-carbon mild steel grade defined by the AISI/SAE classification system. It typically contains around 0.08–0.10% carbon, which gives it excellent ductility and formability compared with medium- or high-carbon steels.
Because of this low carbon content, 1008 steel is known for several important characteristics:
Отлично cold forming ability
добре Заваряване
Гладка повърхностно покритие
добре machinability for light-duty parts
Low production cost
Тези свойства правят 1008 steel one of the most commonly used materials in mass manufacturing and sheet metal fabrication.
Unlike harder steels designed for structural loads, 1008 carbon steel is typically used for components that require shaping, щамповане, огъване, or light machining rather than extreme strength.
Common forms of 1008 steel include:
Cold rolled sheet
Steel strip
Steel wire
Rods and bars
Tubes and pipes
Because of its flexibility and affordability, manufacturers across industries rely on 1008 steel for large-volume production and custom-machined parts.
Химичен състав на 1008 Въглеродна стомана
The chemical composition of 1008 steel is relatively simple compared with alloy steels. Its structure is primarily iron with small amounts of carbon and other elements that influence its mechanical behavior.
| елемент | Съдържание (% по тегло) | Role in the Material |
| Желязо (Fe) | 99.31 – 99.7% | Primary structural metal providing strength and magnetic properties |
| въглерод (° С) | ≤ 0.10% | Improves ductility and weldability while maintaining softness |
| Манган (Мн) | 0.30 – 0.50% | Enhances strength and acts as a deoxidizer during steelmaking |
| Фосфор (П) | ≤ 0.04% | Can increase strength but reduces ductility at higher levels |
| Сяра (С) | ≤ 0.05% | Improves machinability but excessive amounts may cause brittleness |
Желязо (Fe)
Iron forms the base structure of the steel, providing strength, magnetic properties, и издръжливост. The high iron content also makes the material recyclable and environmentally friendly.
въглерод (° С)
The defining feature of 1008 steel is its low carbon level. Lower carbon means:
Greater ductility

Improved weldability
Reduced hardness
This is why 1008 steel is frequently used in deep drawing and stamping operations.
Манган (Мн)
Manganese improves the strength and toughness of steel while also helping remove oxygen during the steelmaking process. Това води до cleaner and stronger metal structures.
Фосфор (П)
Phosphorus slightly increases strength but can reduce ductility if present in high amounts. в 1008 стомана, it is carefully controlled to maintain flexibility.
Сяра (С)
Sulfur improves machinability by helping chips break more easily during cutting operations. въпреки това, excessive sulfur can lead to brittleness, so it is kept within strict limits.
