ASTM A36 Hot Rolled Steel Round bar
alternative steel grade

Our ASTM A36 hot rolled round steel is a high – quality and versatile product that is widely used in various industries. ASTM A36 is a common carbon structural steel specification in the United States, known for its good mechanical properties, including reasonable strength, ductility, and formability. This makes our hot rolled round steel suitable for a broad range of applications, from construction projects to manufacturing components. A36 steel, a low carbon structural steel, is important in the construction and manufacturing industries. It’s characterized by its less than 0.3% carbon content by weight,

A 36 steel is easily machinable, welded, and formed, making it highly versatile.
Its low carbon content limits the effect of heat treatment.
lacks substantial corrosion resistance due to no nickel and chromium.

FAQs About A36 Steel

How does A36 steel’s low carbon content affect its properties? A36’s low carbon content enhances its machinability and weldability but limits the effectiveness of heat treatment and corrosion resistance.
What are the main applications of A36 plates? A36 plates are primarily used in structural applications in buildings, bridges, and oil rigs, as well as in automotive and agricultural applications.
How is A36 carbon steel made? A36 material is made by melting iron ore with coal, burning away impurities, adding alloying elements like manganese and carbon, solidifying into ingots, and then hot rolling.
What are the limitations of A36 carbon steel? The main limitations include its low strength-to-weight ratio, lower strength compared to 1018 steel, and difficulty in accurately determining its precise carbon content.
Can A36 engineering steel be used in high-stress applications? Yes, A36’s combination of machinability, strength, and durability makes it ideal for high-stress applications like bridge and building construction.
