Hi everyone, I am looking for advice for hardening hydraulic valves. As you might know, hydraulic valves are under an emmense performance pressure and have to endure a challenging atmosphere. Most manufacturers use stainless steel for hydraulic valves, hoping that their products have a long durability. While stainless steel is better suited for this purpose than other steel grades, such as carbon steel which tends to corrode really fast, it’s not indestructible. Especially given the fact that hydraulic valves are surrounded by water or steam 24/7 most of the time.
I have found a solution here: https://www.edelstahl-haerten.de/en/ and I was wondering if this can realyl work? How much better can stainless steel get when you use a coating like that?
