Not All Stainless Steel is Equal
316 Austenitic Stainless Steel is the only steel grade that contains Molybdenum,
and Molybdenum is what resists corrosion from feline urine

316 stainless steel is
rarely used in consumer products
From cutlery, cookware to pet products, stainless steel is everywhere in major retail and online stores yet most of them rarely label the grade of steel used and that's intentional because all stainless steel looks identical to the naked eye. Same silver sheen. Same weight. Same finish. A manufacturer can swap 316 for 200-series or 304 economy steel and you'd never know, until it starts to rust, pit, and corrode. 316 stainless steel is rarely in consumer goods. It costs significantly more to produce and most brands simply won't pay for it, especially when the consumers can't tell the difference at the point of purchase.

Molybdenum is only presented in 316 stainless steel
Why does 316 stainless steel matter for your cat? Cat urine contains urea, creatinine, ammonia, and significant chloride concentrations nearly identical in corrosiveness to seawater. 304/201 stainless steel doesn't contain any molybdenum but molybdenum is what prevents corrosion from feline urine. It's the same reason 316 is chosen for surgical instruments, marine hardware, and automotive parts and why Less Litter is made of 316 stainless steel to resist corrosion from daily urine exposure.

The industry truth
Majority of stainless steel consumer products are made from 200-series or 304 economy steel, the cheapest grades available. Not because these products are better engineered but because manufacturers discovered a simple, profitable truth:
"All stainless steel looks the same. So why offer higher quality?"
From the outside, a product made from 304/200-series steel and one made from 316 stainless steel are indistinguishable. There's no law requiring manufacturers to disclose the grade on the packaging. So most don't. They use the cheapest material available and sell it at a premium price.
