What material is 1.4310 equivalent to?
The material AISI 302 is an austenitic stainless steel, also known under the designations 1.4310, BS 301S21 and X10CrNi18-8. The stainless steel AISI 302 belongs to the group of V2A steels and is also known as spring steel, as it is used for the production of technical springs.
What is 1.4305 stainless steel?
Stainless steel type 1.4305 is popularly known as grade 303 stainless steel. Grade 303 is the most readily machineable of all the austenitic grades of stainless steel. The machineable nature of grade 303 is due to the presence of Sulphur in the steel composition.

What is the difference between 1.4310 and 1.4305 stainless steel?
The main difference between 1.4310 and 1.4305 stainless steel lies in their machinability and corrosion resistance. 1.4305 (also known as 303) has higher sulfur content, making it exceptionally machinable but slightly less corrosion resistant than 1.4310 (also known as 301). 1.4310, on the other hand, excels in high strength and ductility after cold working, making it suitable for applications like springs.
What is the difference between 1.4310and 1.4307 stainless steel?
1.4310 and 1.4307 are both stainless steels, but 1.4310 is generally known for its higher strength due to higher carbon content, while 1.4307 (also known as 304L) is known for its weldability and corrosion resistance, especially in welded structures.
What is the difference between 1.4310 and 1.4404?
EN 1.4310 (X10CrNi18-8) and EN 1.4404 (X2CrNiMo17-12-2) are both austenitic stainless steels, but 1.4404 offers superior corrosion resistance due to its molybdenum content. While 1.4310 is known for its high tensile strength when cold-rolled, 1.4404's higher nickel and molybdenum content make it more resistant to corrosion, especially in chloride environments.
