Hot and Cold rolled steel

Understand the main differences between hot and cold rolled steel Hot and cold rolled steel are fundamental materials in the metal processing and manufacturing industries. Choosing between them isn’t about which is better, but about selecting the right material for the specific job. Understanding their distinct properties, manufacturing processes, advantages, and limitations is crucial for designers, engineers, and purchasers. The Core Difference lies in when and how the steel is rolled to achieve its final specifications 1. Hot Rolled Steel (HR): Process: Steel is heated significantly above its recrystallization temperature (typically above 1700°F / 925°C) until it glows. It’s then passed through rollers at this high temperature. Result: Easier shaping, […]

Home » Stainless Steel » 18/0 Stainless Steel 18/0 Stainless Steel Coil Width: 600-1250mm or customizable Thickness: 0.13-4.0mm Alias: AISI 304 / SUS304 Product Introduce 18/0 stainless steel, also known as AISI 430, is a stainless steel with an 18% chromium content and no nickel. It is a ferritic stainless steel, which means it has a body-centered cubic (BCC) crystal structure. The absence of nickel makes it more cost-effective than other stainless steel grades such as 304 (18/8, 18/10) or 316, but also offers slightly reduced corrosion resistance.
