High Performance & Industry Applications


High carbon steel plate is a carbon steel material containing approximately 0.60% to 1.00% carbon, designed for applications that require high hardness, wear resistance, and mechanical strength. It performs particularly well after heat treatment processes such as quenching and tempering, which enhance hardness while maintaining structural stability.

 

Among commonly used grades, 1095 high carbon steel plate (about 0.95% carbon content) is widely applied in:

 

Cutting tools and industrial blades

Heavy-duty springs

Precision components requiring deformation resistance under load

 

Engineering Characteristics


From an engineering application perspective, high strength carbon steel plate provides reliable performance in environments involving friction, impact, and continuous stress.

Balanced Properties: It offers a strong balance between hardness and toughness, making it suitable for both structural and wear-resistant applications.

 

Workability: In the annealed condition, the material supports efficient machining and forming, while after heat treatment it achieves improved hardness and extended service life.

 

Validation: These performance characteristics are commonly validated through standard metallurgical testing and quality inspection processes to ensure consistency across production batches.


In addition to plate products, we also supply related structural materials such as high quality carbon steel pipe, which is widely used in construction frameworks, mechanical systems, industrial piping, and engineering structures requiring strength and durability.

As part of an integrated steel supply solution, we ensure material consistency across different product categories to support diversified industrial requirements. With strong technical experience in steel processing and global supply chain management, we provide reliable and cost-effective material solutions tailored to customer project specifications and application needs.

SAE1045 Medium Carbon Steel Plate

 

Below are the properties of the grades of carbon steel we supply

Low Carbon Steel – Composition of 0.05%-0.25% carbon and up to 0.4% manganese. Also known as mild steel, it is a low-cost material that is easy to shape. While not as hard as higher-carbon steels, carburizing can increase its surface hardness.


Medium Carbon Steel – Composition of 0.29%-0.54% carbon, with 0.60%-1.65% manganese. Medium carbon steel is ductile and strong, with long-wearing properties.


High Carbon Steel – Composition of 0.55%-0.95% carbon, with 0.30%-0.90% manganese. It is very strong and holds shape memory well, making it ideal for springs and wire.


Very High Carbon Steel - Composition of 0.96%-2.1% carbon. Its high carbon content makes it an extremely strong material. Due to its brittleness, this grade requires special handling.
