When sourcing stainless steel materials for industrial or mechanical applications, buyers often compare 1.4310 (AISI 301) and 1.4301 (AISI 304). Although both belong to the austenitic stainless steel family, their chemical compositions, mechanical properties, and application suitability differ significantly.
What material is 1.4310 equivalent to ASTM?
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 steel ?
1.4301 steel pipe is a stainless steel pipe made from the EN 1.4301 grade, which is equivalent to AISI 304. It is one of the most widely used austenitic stainless steels due to its excellent corrosion resistance, weldability, and formability. The pipe is suitable for a wide range of applications, including food processing, chemical handling, architecture, and household equipment.

Which is better, 1.4310 or 1.4301, for corrosion resistance?
1.4301 (AISI 304) generally offers better corrosion resistance than 1.4310 (AISI 301) because it is less prone to intergranular corrosion, especially after welding or under high-temperature conditions. While both can withstand many common environments, the corrosion resistance of 1.4310 decreases with increasing cold working (increased strength) and it is more susceptible to chloride and intergranular corrosion. 1.4310 is suitable for applications requiring higher strength, such as springs.
Can 1.4310 and 1.4301 be welded together?
No, welding 1.4310 and 1.4301 is not recommended because the high carbon content in 1.4310 (also known as AISI 301) can cause intercrystalline corrosion and loss of strength at the weld seam. While 1.4301 (AISI 304) is easily weldable, mixing it with 1.4310 will likely create a weak and brittle weld that is susceptible to corrosion.
What is the price difference between 1.4310 and 1.4301 stainless steel?
On average, 1.4310 stainless steel is slightly more expensive (about US$2,800–3,200/ton) due to additional cold-working processes.
