Carbon steel round bar can be used in many fields such as building, automobile, shipbuilding, petrochemical, machinery, medicine, food, electric power, energy, space, building and decoration, etc. It be made into mould template, mortise pin, column .This kind of steel have good mechanical property, is widely used in structural parts which may support stress alternation, especially made into some connecting rods, bolts, wheel gear... This kind of steel is the most common blanks and materials of shaft parts. Its die welding material model is CMC-E45.

Hexagonal bar, also known as Hexagonal Steel Bar, is a type of steel with a long solid steel bar with a regular hexagonal cross-section. According to different materials, hexagonal rods can be divided into ordinary carbon steel hexagonal rods, stainless steel hexagonal rods, etc. The specifications of hexagonal rods are usually expressed by the length of opposite sides S, and their sizes range from a few millimeters to tens of millimeters. At the same time, the dimensional accuracy of the hexagonal rod is high, up to ±0.01mm, ensuring its stability and reliability in various applications.

Hot-rolled square steel refers to steel rolled or processed into a square cross-section. Square steel can be divided into two types: hot-rolled and cold-rolled; the side length of hot-rolled square steel is 5-250mm, and the side length of cold-drawn square steel is 3-100mm. Stainless steel square steel is mainly used for fine decoration, such as doors and windows.

8620 steel bar is made of a kind of low alloy steel mainly composed of iron, carbon, silicon, manganese, phosphorus, sulfur, chromium, nickel and other elements. It has good hardenability and weldability, and can obtain excellent mechanical properties through heat treatment.

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.

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.
