General Scope
This grade is similar to 4140 in scope which has a higher carbon level giving 4130 an advantage when it comes to weldability, this weldability is achieved at the cost of through section hardenability.
AISI 4130 steel is a low alloy steel that is used in structural designs that may be found in applications such as aircraft engine mounts or welded tubing. It is well known for its ease of welding and ability to harden in commercial applications. It is commonly referred to as chromium-molybdenum steel.
Steel I-Beams, also known as H-Beam, are one of the most common steel profile used in construction and civil engineering. It provide support for buildings and load-bearing walls.
The I-shaped section optimises strength weight ratio & surface usability to provide a highly efficient product. It is right-angle formed & so has high bending resistance, construction application simplicity. It save cost, is light weight and thus is used widely in various industries.
A T-Beam is a load-bearing structure with a t-shaped cross section. The top of the t-shaped cross section serves as a flange or compression member in resisting compressive stresses. The web of the beam below the compression flange serves to resist shear stress and to provide greater separation for the coupled forces of bending.
Other uses for one way to make a T-beam to be more efficient structurally is to use an inverted T-beam with a floor slab or bridge deck joining the tops of the beams. Done properly, the slab acts as the compression flange.
Angle steel bars are perpendicular elongated steel bars connected together as a wave-like product. There are equal angles and unequal angles. Angle steel bar is a simple sectioned carbon structural steel mostly used in metal products fabrication and construction of workshop.
In application, it must has weldability, plasticity deformation performance and high mechanical strength. The raw material to produce angle steel is low-carbon billet. Finished product of angle steel is hot roll formed.
Channel bar, also known as C-Beam, are often used where the flat, back side of the web can be mounted to another flat surface for maximum contact area.
The shape provides superior structural support, making it an ideal product for frames and braces used for machinery, enclosure, vehicle, building and structural support applications. They are also sometimes welded together back-to-back to form a non-standard I-beam.
Round steel bar is a round-shaped solid steel bar. It is hot formed, forged or cold formed. The specification of hot formed round steel is 5.5-250mm.
The small round steel are normally distributed in bundles of 5.5-25mm, and is normally use to make steel bar, bolt and all kinds of mechanical parts. Round steel greater than 25mm are mainly use to make mechanical parts or seamless steel tube ring.
Square Bars are made from very high quality raw material which ensures high durability at its user end. These steel square bar are widely finds its applications in various industrial and commercial sectors.
Steel rebar, also known as deformed bar, is a steel bar or mesh of steel wires used as a tension device in reinforced concrete and reinforced structures to strengthen and hold the concrete in tension. Rebar surface is often patterned to form a better bond with the concrete.
