The main difference between hot rolled and cold rolled steel is in how they are processed. The difference in processing directly affects their shape and properties.

In metal processing, heat treatment shapes material performance, and normalizing and annealing are its most widely used basic technologies. What’s the real difference between normalizing and annealing, both using "heating-holding-cooling"? This article clarifies their core differences from principles to applications, with international standards and cases, to guide precise process selection.

Steel coils are long strips of steel rolled into circular shapes. Many industries use these for strength and versatility.

This guide will systematically break down the key aspects of Brinell and Rockwell hardness testing, including testing principles, practical procedures, applicable scenarios, and result interpretation, to help readers quickly grasp the core points of both methods and easily solve various practical problems in steel hardness testing.

Carbon steel is a metal made mainly from iron and carbon, with small amounts of other elements. It contains up to 2.1% carbon and very low alloy content.

Steel coating refers to the application of a protective or decorative layer onto the surface of steel to prevent corrosion and enhance durability. Steel is strong and widely used but is prone to rust and corrosion if left unprotected. To keep steel lasting longer and performing well, it often needs a protective coating. Steel coating methods create a barrier that protects steel from damage, corrosion, and wear.

“Mild steel” and “carbon steel” are frequently used in the metalworking and construction industry. However, quite a few of us tend to mix them up. For the engineers or fabricators who want to select the right material for their projects, this guide aims to break down the differences, properties, and ideal applications of each.

Carbon may be a small part of steel — usually less than 2% — but it changes the properties of steel profoundly. From soft and ductile low carbon steel to high carbon varieties known for their superior hardness, carbon content determines the steel’s tensile strength, hardness, and ductility. Everything depends on carbon level: machinability, weldability, corrosion resistance, and even how well steel responds to heat treatment. Understanding carbon content helps you pick the right steel. Whether you’re building a bridge, a knife, or a car part, the choice matters. In this post, we’ll break down types of carbon steel, how carbon changes their properties, and why it matters for real-world applications.
