1.4310 vs 1.4301 Stainless Steel: Key Differences
Leave a message
What is 1.4310 stainless steel?
1.4310 is an austenitic stainless steel, also known as AISI 301, that is characterized by its high work-hardening rate, making it suitable for high-strength spring applications. It offers a good balance of corrosion resistance, strength, and ductility after cold working. The steel becomes magnetic after being cold-worked due to a phase transformation in the microstructure.

What is 1.4301 stainless steel?
1.4301 stainless steel is a European designation for the common US 304 grade, an austenitic chromium-nickel stainless steel known for its excellent corrosion resistance, good formability, and weldability. It is used in a wide variety of applications, from kitchen sinks and cutlery to architectural elements and various industrial equipment. Its chemical composition includes approximately 18-19.5% chromium and 8-10.5% nickel.
What is the difference between 1.4310 and 1.4301 Stainless Steel?
The main difference is that 1.4310 (AISI 301) is a high-strength stainless steel designed for applications like springs, while 1.4301 (AISI 304) is a more versatile, general-purpose stainless steel. 1.4310 achieves its higher strength through cold working, which results in a metastable austenitic structure that hardens rapidly, whereas 1.4301 is the most widely used type of stainless steel for general applications.

| Max Service Temperature | 400 – 500°C | 870°C (intermittent) / 925°C (continuous) |
Do 1.4310 and 1.4301 have good corrosion resistance?
1.4310 stainless steel, after heat treatment, possesses high hardness and wear resistance, making it ideal for tools and precision parts. Its corrosion resistance is moderate; use in highly corrosive chemical environments should be avoided.
1.4301 stainless steel exhibits excellent corrosion resistance and formability, making it suitable for industrial piping, food processing, and construction applications. It cannot be hardened but retains good ductility and toughness.
1.4310 vs 1.4301 Stainless Steel:Machining and Manufacturing
1.4310 stainless steel is difficult to machine in its hardened state, requiring specialized tools or annealing before machining.
1.4301 stainless steel is easy to machine, weld, and form, reducing production time for large-scale applications.
is EN 1.4310 stainless steel magnetic?
EN 1.4310 stainless steel, also known as AISI 301, is not inherently magnetic but can become magnetic through cold working.1.4301: Non-magnetic in annealed state, often used in non-magnetic equipment like chemical tanks or medical instruments.
