Stainless steel 1.4301, also known as AISI 304, is one of the most commonly used austenitic stainless steels worldwide. Its outstanding corrosion resistance, formability, and weldability make it a top choice across industries such as food processing, construction, chemical equipment, and architectural projects.

In this guide, we'll walk through the key properties, specifications, typical applications, and how to choose the right stainless steel plate for your project - helping engineers, buyers, and contractors make informed decisions.

What Is Stainless Steel 1.4301 / AISI 304 plate?

Stainless steel 1.4301 is the European standard designation (EN number) for AISI 304 stainless steel. It belongs to the 18/8 Cr-Ni family, referring to its approximate composition of 18% chromium and 8% nickel.

Standard	Equivalent Grade
EN	1.4301
AISI	304
UNS	S30400
DIN	X5CrNi18-10

EN 1.4301 vs AISI 304

EN 1.4301 and AISI 304 are essentially the same austenitic stainless steel. EN 1.4301 is the number of the EU EN standard, which has more detailed regional specifications for the allowable range of trace elements such as carbon (≤0.07%) and manganese (≤2.0%); AISI 304 is the name of the American Iron and Steel Institute (AISI), which focuses more on the general expression in industrial applications. In actual procurement, the two can be used interchangeably.
