Understanding SUS304 Steel: A Comprehensive Guide for Metal Fabricators

SUS304 steel, also known as stainless steel grade 304, is one of the most widely used types of stainless steel in various applications. Its versatility and advantageous properties make it a popular choice among businesses, particularly in the metal fabrication industry. In this comprehensive guide, we will delve into the characteristics, applications, benefits, and potential alternatives of SUS304 steel, providing deep insights for fabricators and decision-makers alike.

What is SUS304 Steel?

SUS304 steel is an alloy composed primarily of iron, with a minimum of 18% chromium and 8% nickel. This combination provides excellent corrosion resistance and improved mechanical properties, making it ideal for numerous applications.

Composition of SUS304 Steel

• Chromium: 18% - Enhances corrosion resistance.
• Nickel: 8% - Improves the overall toughness and ductility.
• Carbon: Max 0.08% - Contributes to strength but too much can reduce corrosion resistance.
• Manganese:
