The name V4A is an old term and stands for chrome-nickel steel with molybdenum addition. Searching for chrome-nickel steel, the Krupp company developed among other materials this steel grade with an austenitic microstructure.

The development of this steel grade took place in 1912, the letter V standing for Versuch (experiment) and the A for austenite. A further, very well-known material from this group is the experimental melt 2 austenite - V2A for short. The designations "V4A" and "V2A" no longer exist, but are still used as terms.

Modern chromium-nickel steel grades, commonly referred to as V4A steels, are available in 1.4401, 1.4404 and 1.4571.

All V4A steel grades can be cold formed very well by bending or deep drawing. Apart from a few exceptions, welding of these steel grades is possible by any conventional method, such as TIG, MAG.

We have a lot of experience in the processing of V4A steel plates.
