Some other websites will list their washers as "18-8" or just "stainless steel".

"18-8" is not an specific alloy
"Stainless steel" is not a specific alloy

These are 304L Stainless Steel

"L" is for Low Carbon, Less than 0.03%. The low carbon make it more corrosion resistant.

"18-8" is not the same as 304L Alloy.
"18-8" is a general classification of the 300 series Stainless steel, which includes 302, 302HQ, 303, 304, 305, 384, XM7 .
 So, If some other company doesn't tell you the specific alloy, you don't know what your getting.
304 Stainless Alloy is more expensive and is harder to machine than 303. 

304L has much better corrosion resistance than 303. 304L is weldable, 303 is not. The term "18-8" has APPROXIMATELY (not exactly) 18% Chromium and 8% Nickel.

The term "304L" alloy stainless steel has a MINIMUM amount of 18% Chromium and a MINIMUM amount of 8% Nickel, COMBINED with a MAXIMUM of 0.03% Carbon. 

Sulfur is added to the 303 alloy which makes it easier to machine, but the sulfur addition does lower Alloy 303’s corrosion resistance to below that of Alloy 304 and also makes 303 not suitable for welding.
