Leave a message
When sourcing stainless steel, understanding material equivalency across standards is essential for accurate procurement and cost-effective decision-making. One of the most commonly requested grades is EN 10088-2 grade 1.4301-but what is it equivalent to in other international standards?
This article will help buyers, engineers, and procurement teams understand the equivalent grades of 1.4301 stainless steel, its key properties, and how to select the right alternative based on your region or technical requirements.
What Is EN 10088-2 Grade 1.4301 Material?
EN 1.4301, designated under EN 10088-2, is a non-magnetic austenitic stainless steel widely used for its excellent corrosion resistance, weldability, and good mechanical strength. It is commonly used in sheet, plate form across industries like food processing, architecture, household appliances, and chemical equipment.

What's the difference between 1.4301 and 1.4307?
1.4301 AISI 304 stainless steel has a high carbon content of 0.07%, while 1.4307 AISI 304L stainless steel has a carbon content of only 0.03%, which reduces the risk of intergranular corrosion in the heat affected zone during welding. As a result, 1.4307 stainless steel has excellent weldability and minimal post-weld annealing requirements.
Both 1.4301 AISI 304 and 1.4307 AISI 304L have comparable corrosion resistance, formability and mechanical properties for applications such as food processing, chemical equipment, building components and piping systems.
1.4301 Stainless Steel Plate Applications
• Food processing and dairy equipment
• Kitchenware, sinks, saucepans, and cutlery
• Architectural paneling, trims, and handrails
• Chemical and pharmaceutical storage tanks
• Tubing, fasteners, nuts, and bolts
If you are working on a specific project, let me know:
• What form you are using (sheet, pipe, bar)
• The environment or chemicals it will face
I can help confirm if 1.4301 is the right choice or if you need an alternative like 1.4307 or 1.4401.
