Product Description

Steel Round Bars

Round Steel is a kind of hollow cylindrical metal material, which is widely used in construction, machinery manufacturing, automobile manufacturing, energy, transportation and other industries.

Round steel is mainly made of carbon steel, alloy steel and tool steel.
Among them, carbon Steel Round steel refers to steel with carbon content within the range of 0.20% to 0.55%.

Carbon steel round steel is an economical and practical structural material with good weldability, plasticity and machinability.
Alloy steel round steel refers to the steel with a certain amount of alloying elements (chromium, manganese, cobalt, boron, molybdenum, vanadium, etc.), which can obtain higher strength, hardness, corrosion resistance and wear resistance.
Tool steel Round steel is a kind of high-speed tool steel material, which has the advantages of high hardness, high red hardness and wear resistance.


Product Description

High-Tensile Alloy Steel Round Bar 4140 Hot Rolled Steel 
Grade: AISI 4140, 4130, 5140, 5120
Alloy structural steel: 4140
Executive standard: ASTM A29/A29M-04 4140 steel. This steel has good workability, small processing deformation, and good fatigue resistance. It is a medium hardenable steel. After heat treatment, 4140 has good strength and good comprehensive mechanical properties, good manufacturability, and yield high.

The highest service temperature is 427 degrees Celsius, 4140 strength, hardenability, good toughness, small deformation during quenching, high creep strength and enduring strength at high temperature.

It is used to manufacture forgings that require higher strength and larger quenched and tempered section than 35CrMo steel, such as large gears for locomotive traction, supercharger transmission gears, rear axles, connecting rods and spring clips that are heavily loaded, and can also be used Drill pipe joints and fishing tools for oil deep wells below 2000m, and can be used for molds of bending machines.
