Carbon Steel and Low-Alloy Steel

2023-12-22

What Is Carbon Steel?


Carbon steel is one of main materials in steel casting industry. According to the carbon contents, carbon steels are classified as three types:


Low-carbon steels(< 0.20% C): A range of tensile properties are provided by heat treatment, and may be hardened to provide high surface hardness with abrasion resistance and good core ductility.

Medium-carbon steels(0.20 to 0.50% C): This grade makes it more durable, pliable and stronger. A range of tensile strengths are possible, with good ductility and impact resistance, easy to for secondary machining in a softened state.

High-carbon steels(> 0.50% C): High strength, good shape memory, is a particularly good option for spring manufacturers. This alloy steel for high strength applications is subject to wear and abrasion and is also suitable for heavy duty applications.

What Is Low-Alloy Steel?


Low-alloy steels contain specified amounts of chromium, nickel or molybdenum to the carbon to enhance harden-ability and toughness. Low-alloy steels are most commonly used for components in the oil and gas, and pump and valve industries, but are also suitable for military vehicles and earth-moving and construction equipment. Common elements added carbon steels are Nickel (Ni), Chromium (Cr) and Molybdenum (Mo). Nickel is added to resist corrosion and provide strength, stability and toughness. Chromium is added to resist wear and corrosion and help the steel to increase strength and harden-ability. Molybdenum is added to withstand temperatures and elevate the strength and harden-ability of the steel.


ABOUT  KEVA
Keva Casting is a professional casting company that focuses on Construction, Machinery, Automobile, Hardware, Pipeline and many other industries.
We provide top quality products with the best service based on our complete production chain including our own mold design, advanced production techniques, and full management of the supply chain. Keva Casting has two factories located in Zhucheng, China's Shandong province.
We use "shell molding", which is a new technique that has been developed in recent years.This new technique has simplified production procedures and reduced air pollution compared with traditional sand casting and investment casting. Shell making and core making are faster to ensure production in enormous quantities. The dimensions and surface finishing are satisfactory for all kinds of industrial requirements. Besides supplying our own formwork & scaffolding systems, our casting products also supply OEM services in various industries.
