Cold drawn hexagonal steel and hot-rolled hexagonal steel are two common types of hexagonal steel, which have certain differences in production process, physical properties, and application fields. This article aims to help readers better understand the characteristics of these two types of steel through comparative analysis.

From the perspective of production technology, cold drawn hexagonal steel is formed by stretching through a cold drawing machine at room temperature, while hot-rolled hexagonal steel is formed by rolling through a rolling mill at high temperatures. This difference leads to differences in physical performance between the two. Cold drawn hexagonal steel has a high surface finish and better dimensional accuracy due to its cold drawing process. Due to the characteristics of the process, its strength and hardness are usually higher than hot-rolled hexagonal steel. Hot rolled hexagonal steel, on the other hand, has good plasticity and toughness due to its high temperature effect during production, making it suitable for applications that can withstand large loads.

In the application field, due to the high precision and strength of cold drawn hexagonal steel, it is more commonly used in mechanical parts and precision equipment with higher requirements, such as various standard parts, fasteners, etc. Hot rolled hexagonal steel, on the other hand, is commonly used in fields such as building structures, bridges, and transmission shafts due to its good toughness and plasticity.

In general, cold drawn hexagonal steel and hot-rolled hexagonal steel each have their own advantages and characteristics, and the choice of material needs to be determined based on the specific application requirements. Through comparative analysis, we can have a clearer understanding of the application scope and applicable industrial fields of the two.
