Product Description

Export Popular S355 Hot Rolled Carbon Steel Ms Iron Square Billet Bar Cold Drawn Bright Mild Steel Square Solid Bar 45# 1020 Forged Square Alloy Steel Rod/Bar
The material of steel Square bar is mainly carbon steel, which contains high carbon element. It has excellent mechanical properties, high strength, good toughness, strong plasticity, and good wear resistance and corrosion resistance. These properties make square steel perform well in various engineering fields.

There are many specifications of square steel, which are mainly distinguished according to their cross-sectional dimensions. Generally speaking, the larger the cross-sectional size of square steel, the stronger its bearing capacity. Common square steel specifications are 8#, 10#, 12#, 14#, 16#, etc., where the numbers represent the section width.

Square steel: It is solid, bar. Different from the square tube, it is hollow and belongs to the pipe. Steel (Steel): It is a material of various shapes, sizes and properties required by steel ingots, billets or steel products through pressure processing
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.

MECHANICAL PROPERTIES:
Yield Point = 36,000 psi
Tensile Strength = 58,000 psi
Elongation = 23% in 2"
Brinell Hardness = 133; Melting Point = 2600F

Carbon Steel Hot Rolled Square Steel Bar

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.

The manufacturing process of steel square bar includes hot rolling and cold drawing. Hot-rolled square steel is made by heating the billet to a certain temperature and pressing it through rolling machinery. The surface of hot-rolled square steel is relatively rough, but its mechanical properties are better. Cold-drawn square steel is made by cold-working hot-rolled square steel. Its surface is smooth, but its strength and toughness are slightly lower than hot-rolled square steel.
