ASTM A36 steel bar is one of the most common grades of steel used in structural applications. This mild carbon steel grade contains chemical alloys that give it properties such as machinability, ductility, and strength that are ideal for use in constructing a variety of structures.

JIS G3101 SS400 Carbon Steel Bar

JIS G3101 SS400 steel is one of the most commonly used hot rolled general structural steel. JIS G3101 SS400 steel is usually supplied as SS400 steel plates, sheets, flats, bars, sections, etc.. No matter what form it is, JIS G3101 SS400 chemical composition will not change.

C45 Carbon Steel Bar

C45 steel bar is a medium carbon steel round bar that offers greater strength and hardness as compared to the low carbon grades. Formability and weldability of S45C is fair when using accepted shop practices. While machinability is good, this grade responds very well to forging and heat treating.

SAE 1008 Carbon Steel Bar

1008 steel round bar are medium carbon and chromium steel which has excellent tensile strength. This is welded and then used for screw machine parts, shafts, pins, spindles and rods. Also available in various other industries. SAE 1008 round bar has many chemical and mechanical properties such as steel grade, tensile strength and elongation.

SAE 1018 Carbon Steel Flat Bar

SAE 1018 carbon steel is a free machining grade that is the most commonly available grade around the world. Although its mechanical properties are not very unique, it still can be easily formed, machined, welded and fabricated.

A36 Carbon Steel Plate

ASTM A36 steel plate is one of the most common grades of steel used in structural applications. This mild carbon steel grade contains chemical alloys that give it properties such as machinability, ductility, and strength that are ideal for use in constructing a variety of structures.

AISI 4140 Alloy Steel Bar

AISI SAE 4140 alloy steel is a chromium molybdenum alloy steel specification widely used in general purpose high tensile steel for components, like axles, shafts, bolts, gears and other applications. AISI 4140 steel gives greater strength and heat treatment capabilities in comparison.

AISI 4340 Alloy Steel Bar

AISI 4340 steel is a medium carbon, low alloy steel known for its toughness and strength in relatively large sections. AISI 4340 is also one kind of nickel chromium molybdenum steels. AISI 4340 steel properties offer good ductility in the annealed condition, allowing it to be bent or formed.
