Stainless Steel - Grades
Stainless steel grades are used to group different types of stainless steel based on how they are made, what they are made of, and how they perform.
They are often identified using a three-digit number (like 304 or 316), though newer systems also exist.
Stainless Steel Grades We Supply
At Ujala Stainless, we stock and supply a wide range of stainless steel grades suitable for diverse industrial applications. These grades belong to different families based on their chemical composition, structure, and properties. Here’s an overview of the major stainless steel families and the grades we offer:
Common Grades:
- 200 Series – Economical and ideal for light-duty applications
- 304 / 304L / 304M / 304H – Most versatile and widely used grade, offering excellent corrosion resistance
- 310 / 310S – Heat-resistant grades, perfect for high-temperature environments
- 316 / 316L – Known for superior corrosion resistance, especially in chemical and marine industries
- 321 – Stabilized stainless steel ideal for high-temperature service
Special Grades:
- 409 / 409M – Primarily used in automotive and exhaust systems for their good formability and oxidation resistance
- Custom & Special Grades – Available on request based on your specific project or industry requirements
We supply these grades in a variety of forms including coils, sheets, plates, pipes, tubes, flanges, fittings, rods, wires, fasteners, and more. These grades are divided into families based on their internal structure (called microstructure).
Austenitic Stainless Steels
These are the most commonly used grades, known for excellent corrosion resistance, non-magnetic nature, and good weldability.
Popular Grades We Supply:
- 304 / 304L / 304M / 304H – Ideal for general-purpose use
- 316 / 316L – Superior resistance to chemicals and marine conditions
- 310 / 310S – Excellent performance in high-temperature environments
- 321 – Stabilized grade for high-heat applications
Ferritic Stainless Steels
Ferritic steels are magnetic, contain little or no nickel, and are known for their good formability and cost efficiency.
Popular Grades We Supply:
- 409 / 409M – Commonly used in automotive exhausts
- 430 – Suitable for kitchen equipment and decorative applications
Duplex Stainless Steels
Duplex combines the best of austenitic and ferritic structures, offering high strength, better corrosion resistance, and excellent performance in aggressive environments.
Grades available on special request. Ideal for:
- Chemical processing
- Marine/offshore equipment
- Pulp & paper industries
