Non-Magnetic Stainless Steels

Welcome to our comprehensive guide on non-magnetic stainless steels. In this article, we'll explore various grades of non-magnetic stainless steels, different shapes and sections they are available in, their production routes, and the offered machinable conditions.

**1. Grades of Non-Magnetic Stainless Steels:**

a. AISI 202:
- AISI 202 stainless steel is a general-purpose, low-nickel, high-manganese stainless steel.
- It provides excellent corrosion resistance and is less prone to becoming magnetic.
- Commonly used in household appliances, automotive trim, and architectural applications.

b. AISI 304:
- AISI 304 is the most widely used stainless steel grade worldwide.
- It contains 18% chromium and 8% nickel, providing good corrosion resistance and non-magnetic properties.
- Commonly found in kitchen equipment, food processing, and chemical containers.

c. AISI 310:
- AISI 310 stainless steel is high in chromium and nickel content.
- Offers high-temperature strength and excellent resistance to oxidation.
- Widely used in heat treatment furnaces, radiant tubes, and high-temperature applications.

d. AISI 316:
- AISI 316 is an austenitic stainless steel with molybdenum, enhancing its corrosion resistance.
- Resistant to chloride environments, making it ideal for marine and coastal applications.

e. AISI 321:
- AISI 321 stainless steel contains titanium, reducing its susceptibility to intergranular corrosion.
- Offers good weldability and is used in aerospace and high-temperature applications.

**2. Shapes and Sections:**

Non-magnetic stainless steels are available in various shapes and sections, including:
- Rounds
- Squares
- RCS (Round Cornered Squares)
- Flats
- Hexagons
- Wire

**3. Size Range for Each Section:**

The size range for each section may vary based on the grade and manufacturer. Common size ranges include:
- Rounds: 5mm to 200mm
- Squares: 5mm to 150mm
- RCS: 20mm to 100mm
- Flats: Thickness - 3mm to 100mm, Width - 10mm to 300mm
- Hexagons: 5mm to 100mm
- Wire: 0.5mm to 10mm

**4. Production Routes:**

Non-magnetic stainless steel sections are produced through various routes, such as:
- Non-vacuum degassed route
- Vacuum degassed route

**5. Machinable Conditions:**

Non-magnetic stainless steels are offered in different machinable conditions, including:
- As rolled
- Annealed
- Normalized
- Spherodize annealed
- CHQ (Cold Heading Quality)

Please note that the availability of specific shapes, sections, and machinable conditions may vary depending on the supplier and manufacturer. Always consult with the supplier to get the most up-to-date information for your specific requirements.

In conclusion, non-magnetic stainless steels are a versatile group of materials with excellent corrosion resistance and non-magnetic properties. They find applications across various industries, and their availability in different shapes and machinable conditions makes them suitable for a wide range of engineering and design applications.
