Steel used

[cut it out]

So at work today the inspectors have a new toy in a X-ray gun you point at steel and it tells you what it is. So I volunteered my Alox cadet and it read 430 ss. Everyone probably knows but thought I'd share

I think their machine is a bit off. 430 is what they use for trim on refrigerators, or something.

The standard steel used is 1.4110 though there are variations in the steel type and Rc scale depending on the where the steel is going. For instance the steel used in the blade for the swiss army knife is 1.4110, but for the springs and various steel riggings 1.4021 and 1.4031 are used respectively.
