Steel rebar is a steel material used for reinforced concrete and prestressed reinforced concrete. Its cross section is usually round, sometimes square with rounded corners. The main types of rebar include plain round bars and deformed bars. Plain round bars are actually small round bars and coils of ordinary low-carbon steel, while deformed bars have ribs on the surface, usually 2 longitudinal ribs and transverse ribs evenly distributed along the length. The shape of the transverse ribs can be spiral, herringbone or crescent.

We offer a wide range of high-quality seamless steel pipes made from various materials such as 10#, 45#, and more. Available in hot rolled, cold rolled, and cold drawn specifications, our pipes are suitable for fluid, boiler, gas, and oil applications.

American standard ASME/AISI/ASTM standard 4140 alloy seamless steel pipe is the core material in the fields of machinery manufacturing, petrochemical industry, automobile industry, etc., with high strength, wear resistance and corrosion resistance. As a medium carbon chromium-molybdenum alloy structural steel, 4140 achieves excellent comprehensive performance through quenching and tempering heat treatment, and is widely used in high-pressure pipelines, mechanical parts and oil drilling equipment.
Alloy composition: Contains 0.38-0.43% carbon (C), 0.75-1.00% manganese (Mn), 0.80-1.10% chromium (Cr) and 0.15-0.25% molybdenum (Mo). The grain structure is optimized through microalloying technology to improve hardenability and fatigue resistance.
