A36 is a low-carbon steel containing manganese, phosphorus, sulfur, silicon and copper. A36 has good weldability and high yield strength. A36 carbon steel bar is commonly used as a variety of structural steel parts.

Bright steel bars are made from cold drawn steel and have a shiny, polished finish. They are known for their precision and accuracy in terms of dimension and are commonly used in the production of precision components such as gears, shafts, and bearings.

A572 steel bars have good strength, ductility and workability, making them ideal for structural applications. These characteristics make the A572 relatively simple to shape into different structures, while maintaining the ability to withstand large stresses and loads.

A105 is an ASTM specification for steel forgings, primarily for carbon steel forged pipe components. The type of carbon steel wrought alloy involved is a low carbon, manganese and silicon steel similar to the AISI 1330, but with a lower manganese content.

AISI 1018 carbon steel bar has a chemical composition of carbon, chromium, manganese, molybdenum, phosphorus, sulfur and silicon. AISI 1018 carbon steel is a free machining grade that is the most commonly available grade around the world.

AISI 1025 steel bar is a medium carbon steel that offers plasticity, workability and strength. The steel contains between 0.22% and 0.28% carbon, so it is stronger than low carbon steel and more workable and malleable than high carbon steel.
