Most Common Types of Stainless Steel?

Stainless steel is a crucial material in numerous industries, valued for its strength, durability, and resistance to corrosion. Its versatility allows it to be used in everything from heavy industrial machinery to household appliances. However, not all stainless steel is created the same. There are several types, each designed for specific purposes and industries. In this article, we will explore the most common types of stainless steel and their applications, along with why Mangalam Worldwide is a trusted name among stainless steel manufacturers and suppliers.

What is Stainless Steel?

At its core, stainless steel is an alloy primarily made from iron and carbon, with chromium added to enhance its corrosion resistance. The proportion of chromium, along with other elements like nickel, molybdenum, and nitrogen, varies across different grades of stainless steel. These variations influence the material's strength, flexibility, and resistance to heat and corrosion. Each grade is designed for specific uses, making it essential to understand the differences when selecting stainless steel for various applications.

Common Types of Stainless Steel and Their Uses

Below are the most commonly used types of stainless steel, each designed to meet different industrial and commercial needs.

1. Austenitic Stainless Steel (300 Series)

Austenitic stainless steel is the most widely used type due to its superior corrosion resistance and versatility. It includes common grades like 304L and 316L.

• Grade 304L Stainless Steel: Often called the “workhorse” of stainless steel, 304L is frequently used in kitchen appliances, industrial machinery, and architectural structures. It has high chromium (18%) and nickel (8%) content, making it resistant to corrosion and suitable for general-purpose applications.
• Grade 316L Stainless Steel: Similar to 304L, but with added molybdenum, 316L offers enhanced resistance to chloride and saline environments, making it ideal for marine applications, chemical processing, and industries facing harsh conditions.

At Mangalam Worldwide, we supply high-quality austenitic stainless steel products that deliver long-lasting performance in a wide range of demanding environments.

2. Ferritic Stainless Steel (400 Series)

Ferritic stainless steel is magnetic and typically contains chromium with little to no nickel. This type is generally more affordable than austenitic stainless steel and is suitable for applications requiring moderate corrosion resistance.

• Grade 430 Stainless Steel: Commonly used in automotive trim, kitchen appliances, and decorative applications. It offers corrosion resistance in mildly corrosive environments and has good thermal conductivity.
• Grade 409 Stainless Steel: Frequently used in automotive exhaust systems, grade 409 is known for its high-temperature resistance. While it provides lower corrosion resistance than 430, it is still a durable and cost-effective option for automotive applications.
• Grade 431 Stainless Steel: Known for its excellent strength and moderate corrosion resistance, grade 431 is ideal for high-stress applications like bolts, screws, and shafts. It also has superior resistance to oxidation and is commonly used in marine, aerospace, and chemical industries.

Ferritic stainless steels from Mangalam Worldwide are well-suited for industries needing both strength and moderate corrosion resistance.

3. Martensitic Stainless Steel (400 Series)

Martensitic stainless steel is known for its high strength and hardness, making it ideal for applications requiring durability. These steels are magnetic and have higher carbon content, which gives them greater hardness.

• Grade 410 Stainless Steel: Widely used in cutlery, surgical instruments, and industrial knives, grade 410 offers excellent wear resistance and is highly machinable.
• Grade 420 Stainless Steel: Known as “cutlery-grade” stainless steel, grade 420 is commonly used in knives and other cutting tools due to its high carbon content and ability to retain sharp edges.

Mangalam Worldwide provides martensitic stainless steel for industries that need high-strength and precision in manufacturing tools and equipment.

4. Duplex Stainless Steel

Duplex stainless steel combines the properties of both austenitic and ferritic stainless steel, offering a better price point while maintaining excellent corrosion resistance and superior strength. It is ideal for heavy-duty applications requiring both durability and strength.

At Mangalam Worldwide, we offer high-performance duplex stainless steel solutions for industries that demand materials capable of withstanding harsh conditions and offering long-term durability.

5. Precipitation-Hardening Stainless Steel

Precipitation-hardening (PH) stainless steel is used in applications requiring high strength and wear resistance. This type of stainless steel can undergo heat treatment to develop exceptional mechanical properties, making it ideal for demanding industries.

• Grade 17–4 PH Stainless Steel: This popular grade offers a combination of strength, hardness, and corrosion resistance, making it ideal for aerospace, chemical processing, and the oil and gas industry.

At Mangalam Worldwide, we supply precipitation-hardening stainless steel for industries that require high-performance materials capable of withstanding extreme mechanical stress.

Selecting the Right Stainless Steel for Your Needs

We've discussed the most common grades of stainless steel, but Mangalam Worldwide also offers a range of other high-performing grades, such as 310, 316L, 316 Ti, 321, and duplex.

• Grade 310 Stainless Steel: Known for its excellent oxidation and high-temperature resistance, grade 310 is used in furnace parts, heat exchangers, and other high-heat applications.
• Grade 316 Ti Stainless Steel: This alloyed version of 316 includes titanium for enhanced corrosion resistance and improved strength, making it suitable for high-temperature applications in the chemical and pharmaceutical industries.
• Grade 321 Stainless Steel: Known for its resistance to high temperatures and intergranular corrosion, grade 321 is commonly used in applications such as aerospace, petrochemical plants, and high-temperature exhaust systems.
• Duplex Stainless Steel: Combining the best properties of both austenitic and ferritic stainless steels, duplex stainless steels offer exceptional strength and resistance to pitting and crevice corrosion, making them ideal for marine, chemical, and offshore applications.
