AISI/SAE 4140 Alloy Steel Bar

4140 steel is a 1% chromium-molybdenum general-purpose high-strength steel, usually hardened and tempered in the tensile range of 850-1000 Mpa. 4140 steel has improved machinability, which greatly increases feed and speed, while extending tool life without affecting mechanical properties. The prehardening and tempering 4140 can be further case hardened by flame or induction hardening and nitriding. AISI4140 steel bars have high strength, hardenability, good toughness, small deformation during quenching, and high creep strength and durable strength at high temperatures.

Application area

First, the construction field
Carbon structural steel hot rolled steel rod is one of the indispensable building materials in the construction field. It is widely used in building concrete reinforcement materials to increase the tensile strength and seismic performance of concrete. In high-rise buildings and large-scale infrastructure construction, carbon structural steel hot rolled steel rod is a key factor to ensure the structural stability and safety of buildings.
Second, the field of transportation
Carbon structural steel hot rolled steel rod plays an important role in the manufacture of vehicles. For example, hot-rolled steel rods can be used to produce components such as tire support springs, engine valve springs, and drive shafts for cars. In addition, a large number of hot-rolled steel rods are also used in shipbuilding, such as anchor chains and cables.
Third, the manufacturing field
Carbon structural steel hot rolled steel rods are also widely used in various machinery manufacturing and equipment manufacturing fields, such as industrial robots, power equipment, metallurgical equipment and mechanical equipment. Because of its hard material, good toughness and strong load-bearing force, it also plays an irreplaceable role in the manufacture of machine parts and equipment.
