Stainless Steel Machining: Guide to Grades, CNC Processing and Applications

Introduction to Stainless Steel

Stainless steel is a corrosion-resistant alloy composed primarily of iron, chromium, nickel, and other elements that enhance its durability, strength, and heat resistance. It is widely used in various industries due to its excellent mechanical properties and aesthetic appeal.

Specific Types of Stainless Steel (ISO Standards)

Stainless steels are classified based on their microstructure and composition. Common ISO-standard stainless steels include:

• Austenitic (e.g., 304, 316): High corrosion resistance, used in medical and food industries.
• Ferritic (e.g., 430, 446): Good formability and oxidation resistance, used in automotive applications.
• Martensitic (e.g., 410, 420): High strength and wear resistance, ideal for cutlery and tools.
• Duplex (e.g., 2205, 2507): Balanced strength and corrosion resistance, used in marine environments.
