EN Standard 1.4436 (AISI 316L) Super austenitic stainless steel has a range of common applications, mainly in industries where its corrosion resistance, mechanical properties and cost-effectiveness are well suited. Some typical applications of 1.4436 stainless steel include:

Food and Beverage Processing: – Equipment, tanks and piping for food, dairy and beverage plants
– Food processing machinery and appliances

Construction and Civil Engineering: – Curtain wall with water-treated steel frame
– Pier structures and offshore platforms

General industrial applications: – Process equipment, storage tanks and pipelines for various industries
– Architectural and decorative elements

Low and high temperature applications: – Liquefied Natural Gas (LNG) Facilities
– Petrochemical plants and power generation equipment

Key factors that make 1.4436 super austenitic stainless steel a suitable choice for these applications include:

Corrosion resistance: – 1.4436 has good resistance to general corrosion, pitting corrosion and crevice corrosion, making it suitable for use in various industrial environments.
– While not as resistant to chloride-induced stress corrosion cracking as 2205 duplex stainless steel, 1.4436 still provides adequate corrosion protection in many applications.

Mechanical Properties: – 1.4436 provides a good balance of strength and ductility, with typical tensile strengths ranging from 480 to 680 MPa and elongations of approximately 40-50%.
– The austenitic microstructure gives the material high toughness, making it suitable for applications where impact resistance is important.

Thermal and Low Temperature Performance: – 1.4436 maintains its mechanical properties and corrosion resistance at both high and low temperatures, allowing its use in low and high temperature environments.

Cost-Effectiveness: – Compared to higher alloy stainless steels such as 2205 duplex, 1.4436 is a more cost-effective solution for applications where slightly lower corrosion resistance and mechanical properties are acceptable.

1.4436 Super Austenitic Stainless Steel’s versatility and cost-effectiveness make it a popular choice for applications in the food, pharmaceutical and general industrial sectors, where its performance characteristics meet the required standards.
