What is 1.4301 stainless steel material?
Stainless steel types 1.4301 and 1.4307 are also known as grades 304 and 304L respectively. Type 304 is the most versatile and widely used stainless steel. It is still sometimes referred to by its old name 18/8 which is derived from the nominal composition of type 304 being 18% chromium and 8% nickel.
What is the material equivalent of 1.4306?
1.4306 / AISI 304L / X2CrNi19-11. 1.4306 - AISI 304L is essentially a more highly alloyed version of 1.4307. Due to the slightly higher chromium and notably higher nickel content, 1.4306 - AISI 304L is more corrosion resistant than 1.4307.
What is 1.4307, X2CrNi18-9, AISI 304L?
Grade similar to material 1.4301 / AISI 304 with additionally reduced carbon content. The application is the same as the model grade. Steel often comes with AISI 304 as double-certified in the form of sheets, pipes or bars.
What is the difference between 1.4301 and 1.4306?
| Feature | 1.4301 | 1.4306 |
|---|---|---|
| Corrosion Resistance | Good, general-purpose | Superior, especially in welded areas, due to higher nickel and lower carbon |
| Nickel Content | Typically 8-10.50% | Typically 10-12% |
| Carbon Content | Max 0.07% | Max 0.03% |
| Deep-drawing properties | Good | Better |
| Typical Use | Architecture, vehicle construction, kitchenware, medical equipment, food processing | Applications where higher corrosion resistance is crucial, and more welding is required |

What is the difference between 1.4306 and 1.4307?
The main difference is that 1.4306 is a more highly alloyed and more corrosion-resistant version of 1.4307. Both are low-carbon stainless steels, but 1.4306 contains slightly higher levels of chromium and nickel, giving it superior resistance, especially in certain chemical environments. However, 1.4307 generally has better machinability and better resistance to intergranular corrosion after welding for thicker materials.
What is the difference between 1.4301 and 1.4307?
In summary, EN 1.4301 (AISI 304) is generally preferred when higher mechanical strength and wear resistance are required, while EN 1.4307 (AISI 304L) is a better choice for applications involving extensive welding or exposure to corrosive environments. The final choice depends on the specific needs of the application.
