AISI 304 EN Information Article

AISI 304 EN is one of the most widely used stainless steel grades in the world. It is known for its excellent corrosion resistance, high ductility, and versatility. In this article, we will discuss the features and applications of AISI 304 EN.


AISI 304 EN is an austenitic stainless steel that contains 18% chromium, 8% nickel, and a small amount of carbon. The material has a maximum carbon content of 0.08%, thus making it an ultra-low carbon grade. This aspect significantly improves the weldability of the material and allows for easier fabrication of complex shapes. AISI 304 EN is also non-magnetic, making it suitable for numerous applications, especially in the food and beverage industry.

Corrosion Resistance

AISI 304 EN has excellent corrosion resistance properties when compared to other stainless steel grades. It can withstand exposure to corrosive environments such as acids, bases, and salts. The chromium content enables the formation of a passive chromium oxide layer on the metal’s surface, which protects it from further corrosion. This feature makes it ideal for applications in marine, chemical, and petrochemical industries.

Mechanical Properties

AISI 304 EN has high tensile strength and an excellent yield strength that is twice that of regular carbon steel. It is also highly ductile, allowing it to be formed and drawn into different shapes without cracking or deformation. This makes it a popular choice for producing fittings, tubing, and other critical components.


AISI 304 EN finds its use in various industrial applications such as:

1. Food and Beverage Industry: AISI 304 EN is highly suitable for use in the food and beverage industry due to its non-magnetic nature, easy weldability, and excellent corrosion resistance.

2. Medical Devices: It is commonly used in medical devices due to its biocompatibility, corrosion resistance, and ease of sterilization.

3. Chemical and Petrochemical Plants: AISI 304 EN is widely used in chemical and petrochemical plants due to its excellent corrosion resistance properties.

4. Architecture and Construction: It finds its use as cladding, roofing, and other architectural applications, thanks to its corrosion resistance and aesthetic appeal.


AISI 304 EN is an outstanding stainless steel grade that offers a high degree of corrosion resistance, ductility, and easy fabrication. It is widely used in various applications and industries, including food and beverage, medical, chemical, and architectural. Its excellent features make it a popular choice for manufacturers looking to produce high-quality components that can withstand harsh environments.
