AISI Series Steel Round Bars

These AISI Steel Round Bars are extensively used in metallurgical, mechanical, electrical construction field, ships, military and automobile industry. These bars belong are wisely made of high carbon steel which is also a quenching and tempering steel with high strength. It is widely for manufacturing moving parts which needs high strength, such as plunger of air compressor and pump, rolled shaft, connecting rod, endless screw, gear rack, dowel of heavy machines. These round bars can be also used in the production of wear resistant parts such as machine tool shaft, crank axle and transmission shaft.

These AISI 4130 Round Bars have great thermal and physical properties as compared other grades. Produced by an excellent combination of rolling and forging techniques, these round bars feature even surface and high strength. Commonly used for applications where flame hardening is utilized for surface hardness, these round bars are highly suitable for various quench and temper heat treatment, forming and machining uses.

We supply AISI 4140 Steel Bar of high-quality to our client. These bars are wisely made of different grades of steels with compositions of boron, carbon, manganese and molybdenum. The elastic modulus of our steel bars is also considerable for fitting to various user needs. These are also highly ductile. Besides, these can also be heated and welded at considerably normal temperatures suitable for heavy industries. As such, we are highly in compliance with the market standards in supplying these steel bars to the client.

We offer these Alloy Steel Round Bars in heat treated and annealed forms. Extensively used in a number of different applications including automotive industry, these round bars are applied in manufacturing of crankshafts, engine construction, spindles, gears and axles. Best known in the industry for their high strength, superior corrosion resistance and excellent weathering properties, these bars are offered to clients in a wide range of dimensions for meeting their exact needs.

These AISI 4340 Steel Bars are mainly used in power transmission gears and shafts, aircraft landing gear, and other structural parts. Superior quality nickel chromium molybdenum alloy steel is used in manufacturing these bars. Widely used in oil & gas industry, these bars have high tensile strength. Offer toughness and high strength in the heat treated condition; these bars are usually supplied under quenched and tempered condition. These bars can be easily machined using all conventional techniques. Feature good ductility and formability in the annealed condition, these bars can be bent or formed by pressing or spinning in the annealed state.

This AISI 01 Steel is considered as one of the most well respected oil -hardening tool and die steels. Easy to machine, this steel is carefully processed for no major dimensional changes. It has good abrasion resistance and sufficient toughness for normal tool- and- die applications. It is preferred for the majority of applications when it is essential to have a safer hardening tool - and-die steel. These are extensively used for cold - forming, blanking and bending dies, forming rolls, broaches, knurling tools and gages.

This AISI H13 Tool Steel features high harden- ability, excellent wear resistance and toughness. This steel features good thermal and shock resistance. In addition, it can also tolerate water cooling in service. This steel grade is best known for its great homogeneity and an exceptionally fine structure, resulting in improved machine-ability, polish-ability and high temperature tensile strength. It is highly recommended for use in a variety of hot work applications including extrusion tools, pressure die casting tools, hot shear blades, forging dies, plastic molds and stamping dies. In addition, it is also great for aluminum die-casting tools and plastic mold tools requiring a very high polish.

This AISI H21 Steel is mostly utilized as instruments for manufacture of hollows, screws, rivets, nuts and bolts & hot work devices. It is a hot work tool steel for oil or air solidifying to grow high hot quality, maintenance of hardness and warmth checking resistance. Widely used for manufacturing die casting tools, forming dies, die inserts and hot shear blades, this steel grade with good toughness include tungsten chromium carbon vanadium. It is normally available in round, flat and square shapes.
