Hexagonal steel is a kind of section steel, also known as hexagonal bar, and the cross-section is a regular hexagonal bar. Hollow hexagonal steel is widely used in various structural parts, tools and mechanical parts. Compared with the round tube, the hexagonal tube generally has a larger moment of inertia and section modulus, and has a larger resistance to bending and torsion, which can greatly reduce the weight of the structure and save steel.

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.

A106 GrB strength grade 415MPa. ASTM A106Gr. B carbon steel round bar is a kind of low carbon steel widely used in petroleum, chemical and boiler industries. The material has good mechanical properties. Carbon steel round bar for high-temperature operation ASTM A106 GR. B, steel grade: SA106B, Specification: 1/4 ″ - 28 ″, 13.7-711.2mm Steel grade: GRAD B, Standard: ASTM A106 - American Society for Testing and Materials.

Performance and application of material ST37: the material has good performance, that is, through cold rolling, it can obtain cold rolled strip and steel plate with thinner thickness and higher precision, with high straightness, high surface finish, clean and bright surface of cold rolled plate in Taiwan Strait, easy to be coated, various varieties, wide application, high stamping performance, non aging, and low yield point.

X42 Carbon steel round bar is the round bar with steel grade of X42.

Now the common round steel processes are hot rolling, forging and cold drawing. The steel quality and application scope of these three processing modes will also have some differences. For example, the specification of hot rolling is generally 5.5-250MM, and the appropriate steel can be selected according to the actual needs.
Generally, parts are manufactured by machinery or used as seamless steel pipe blanks, and steel is also used in some building construction.
Round steel has relatively high strength, high hardenability and very good toughness, so its pressure bearing capacity is also guaranteed. Even if it is used at high temperature, the creep strength is high and the durability is also guaranteed.

Round steel belongs to carbon structural steel for construction and machinery, while square steel belongs to carbon structural steel for machinery. Both of them are simple section steel, and their section shapes are respectively round and square. Low carbon is mainly used for drawing wire, forging rivets, bolts, nuts and other metal products of raw materials. Medium carbon round steel and square steel are generally used to make mechanical structural parts.

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.
