300 series stainless steel is a group of austenitic steels known for its exceptional qualities. This versatile material excels in rust and corrosion resistance, making it a durable choice for many applications. There are a variety of grades within the 300 series; 302, 304, and 316 are the most common. Each offers varying levels of properties depending on its specific chromium and nickel content

300 Series Grades at Alliance Fabrication & Manufacturing

We offer a variety of 300 series grades to meet your specific needs:

301: 

• 301 Stainless Steel is a type of austenitic chromium-nickel stainless steel that can be used in annealed and cold working conditions. It provides excellent stretch formability and the highest strength in cold working conditions.

302: 

• 302 Stainless Steel is a high-carbon alloy known for its exceptional toughness, outstanding corrosion resistance, and ease of machining. It is primarily used in the food and beverage industry and pressure vessels.

304L:

• 304L (low carbon) is austenitic steel, the most versatile and widely used stainless-steel family member. It is commonly found in both home and commercial operations. Alloy 304L exhibits excellent corrosion resistance, high ease of fabrication, and outstanding formability. Austenitic stainless steels are also considered the easiest to weld high-alloy steels. 

316: 

• 316 stainless steel, or A4 stainless, is renowned for its excellent corrosion resistance. It is chemically like 304, containing high levels of chromium and nickel, along with silicon, manganese, and carbon, with iron as the remainder. However, 316 includes a significant amount of molybdenum (2-3%), lacking in 304.
• This molybdenum gives 316 stainless steel superb saltwater and marine applications, earning it the nickname "marine" grade. 316 stainless steel is widely used in chemical processes and high-salinity environments. For these reasons, it is also often utilized for chemical processing and storage equipment, medical and surgical devices, refinery equipment, and marine equipment.

316L: 

• 316L stainless steel is a medical-grade metal that is hypoallergenic and suitable for people with sensitive skin. It is a marine-grade stainless steel with good strength and high corrosion resistance. It finds applications in marine settings, biomedical implants, body jewelry, and food processing equipment.
