what is 1.4301 stainless steel equivalent?

what is EN 1.4301 material?
EN 1.4301 is the European standard for austenitic stainless steel, commonly known as AISI 304. It is a popular, versatile, and corrosion-resistant stainless steel widely used for kitchen equipment, tanks, tubing, and architectural applications due to its good workability and resistance to corrosion.

 

what is 1.4301 stainless steel equivalent?

The stainless steel grade 1.4301 is equivalent to AISI 304 and is also known by the EN designation X5CrNi18-10. This common austenitic stainless steel is also designated as UNS S30400 and has other equivalents like 304S11 and EN58E.

STANDARD	UNS	WERKSTOFF NR.	AFNOR	EN	JIS	BS	GOST
SS 304	S30400	1.4301	Z7CN18‐09	X5CrNi18-10	SUS 304	304S31	08Х18Н10

 

Is 1.4301 the same as AISI 304?
Yes, 1.4301 is the EN/European designation, and AISI 304 is the American equivalent. Both have similar composition and performance.

Weldability
The stainless steel material 1.4301 (AISI 304 / X5CrNi18-10) can be used for all common welding processes (with the exception of gas welding). No filler material is required.

 

Heat treatment and hot forming
Solution heat treatment (cooling by air or water): 1000-1100 °C
Hot forming (cooling by air): 1200-900 °C

 

Machinability
This stainless steel is generally easy to machine. However, like all austenitic materials, stainless steel AISI 304 hardens during machining. Therefore, it is important to ensure that the depth of cut is sufficient.

 

Are 1.4301 and 1.4401 steels magnetic?

1.4301 (corresponding to 304 stainless steel) and 1.4401 (corresponding to 316 stainless steel) are both austenitic stainless steels and are generally non-magnetic or only very weakly magnetic in the annealed state.

 

What is the difference between 1.4301 and 1.4306?

The main difference is that 1.4306 (X2CrNi19-11) has a higher corrosion resistance than 1.4301 (X5CrNi18-10) due to its higher chromium and nickel content, though both are austenitic stainless steels. Grade 1.4306 has slightly higher chromium and a more significant increase in nickel, making it better suited for applications requiring increased corrosion resistance, such as those involving nitric acid production.
