Stainless steel is widely used in CNC machining due to its excellent corrosion resistance, strength, and durability. The most commonly used grades include:

• 304 Stainless Steel
• 316 Stainless Steel
• 420 Stainless Steel
• 17-4 PH Stainless Steel

These grades offer different mechanical properties and corrosion resistance, making them suitable for various applications.

304 Stainless Steel

The most common austenitic stainless steel, known for its good corrosion resistance and formability.

International Grades: AISI 304, DIN 1.4301, EN X5CrNi18-10

316 Stainless Steel

Offers superior corrosion resistance to 304, especially in marine environments.

International Grades: AISI 316, DIN 1.4401, EN X5CrNiMo17-12-2

420 Stainless Steel

A martensitic stainless steel with higher strength and hardness.

International Grades: AISI 420, DIN 1.4021, EN X10Cr13

17-4 PH Stainless Steel

Precipitation hardening stainless steel with excellent strength and corrosion resistance.

International Grades: AISI 630, DIN 1.4542, EN X12CrNiTi17-4

304 Stainless Steel

Performance: Good corrosion resistance, excellent formability, weldability, and machinability.

Advantages: Cost-effective, widely available, suitable for various applications.

Disadvantages: Lower strength compared to other grades, not suitable for high-temperature environments.

316 Stainless Steel

Performance: Superior corrosion resistance, especially against chlorides and marine environments.

Advantages: Ideal for harsh environments, maintains strength at higher temperatures.

Disadvantages: More expensive than 304, slightly lower machinability.
