1.4310 vs 1.4301 stainless steel pipe: difference
Leave a message
When selecting stainless steel pipes for industrial or structural applications, understanding the differences between 1.4310 (AISI 301) and 1.4301 (AISI 304) is essential. Although both are austenitic stainless steels under the EN standard, they differ in mechanical properties, corrosion resistance, work hardening behavior, and typical applications.
What is 1.4301 steel pipe?
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.
What is 1.4310 stainless steel tube?
1.4310 stainless steel tube refers to tubing made from EN 1.4310 grade, also known as AISI 301. It is an austenitic stainless steel with higher carbon content and lower nickel than 1.4301, which allows it to achieve high strength through cold working. This makes it ideal for applications requiring spring-like properties, fatigue resistance, or high tensile strength.

Mechanical Properties & Work Hardening
| Property | 1.4310 | 1.4301 |
|---|---|---|
| Yield Strength (MPa) | ~275 (annealed), up to 1000+ (cold-worked) | ~230 |
| Tensile Strength (MPa) | ~650–950 | ~500–700 |
| Hardness | 150-180 HB | 140-170 HB |
Corrosion Resistance
Both 1.4310 and 1.4301 stainless steel pipes contain 18-20% chromium and 8-10% nickel, and have similar corrosion resistance and can resist air, water, and weak acids and alkalis; however, 1.4310 has a lower carbon content, making it less likely to experience intergranular corrosion after welding, and is more stable in humid, welded piping systems (such as water pipes in food factories); 1.4301 has sufficient corrosion resistance in non-welding, dry scenarios (such as indoor handrail pipes), and is more cost-effective.
Cost
For projects that require welding or long-term exposure to moisture, 1.4310 pipes can reduce maintenance costs due to rust; for simple non-welding applications, 1.4301 pipes are reliable and less expensive.
