316 Stainless Steel

Buy 316 Stainless Steel Online

Introducing our 316 Stainless Steel, an advanced austenitic alloy renowned for its exceptional corrosion resistance, especially in chloride-rich and acidic environments. This premium material is engineered for demanding applications where durability and reliability are paramount.

Superior Corrosion Resistance

The standout feature of 316 Stainless Steel is its enhanced resistance to corrosion, particularly against pitting and crevice corrosion in chloride environments such as seawater. The addition of molybdenum (2–3%) significantly improves its resistance to aggressive chemicals, including sulfuric acid, hydrochloric acid, and acetic acid, compared to standard grades like 304. This makes it the preferred choice for marine applications, coastal architecture, and chemical processing industries.

Outstanding Mechanical Properties

Beyond corrosion resistance, 316 Stainless Steel offers excellent tensile strength, toughness, and ductility, making it suitable for high-stress and high-temperature applications. Its austenitic structure also ensures good formability and weldability, supporting complex fabrication for industrial, architectural, and marine projects.

Exceptional Mechanical Properties

With a tensile strength ranging from 500–700 MPa and excellent ductility, 316 Stainless Steel maintains its toughness under mechanical stress. Its austenitic structure also allows for easy welding and fabrication, supporting complex designs and industrial manufacturing processes.

Mechanical Properties

316 Stainless Steel offers robust mechanical properties, with a tensile strength ranging from 500 to 700 MPa, depending on the specific product form and heat treatment. This strength, combined with excellent toughness, ensures the material performs well under mechanical stress and at elevated temperatures. Its austenitic structure provides good formability and weldability, making it suitable for complex fabrication processes.

High-Temperature Performance

This alloy maintains its structural integrity at elevated temperatures, with oxidation resistance up to approximately 870°C in intermittent service and 925°C in continuous service. However, prolonged exposure between 425°C and 860°C may lead to carbide precipitation, potentially compromising corrosion resistance. In such cases, the low-carbon version, 316L, is recommended for its improved resistance to sensitization.

Chemical Composition

The typical composition of 316 Stainless Steel includes:

• Chromium (Cr): 16–18%
• Nickel (Ni): 10–14%
• Molybdenum (Mo): 2–3%
• Manganese (Mn): Up to 2%
• Silicon (Si): Up to 0.75%
• Carbon (C): Up to 0.08%
• Phosphorus (P): Up to 0.045%
• Sulfur (S): Up to 0.03%
• Nitrogen (N): Up to 0.10%

The addition of molybdenum enhances the alloy’s resistance to pitting and crevice corrosion in chloride environments, making it more suitable than 304 Stainless Steel for marine and chemical applications.

Versatile Applications

Due to its outstanding properties, 316 Stainless Steel is widely used across various industries:
Marine and Coastal Applications: Boat fittings, railings, and offshore platforms benefit from its resistance to saltwater corrosion.

Chemical and Petrochemical Industries: Equipment exposed to aggressive chemicals, such as reactors and heat exchangers, utilizes 316 for its durability.
