The cheap Chinese ones are plated with nickel or something with copper underneath.

I have not had any issues with stainless steal tools unless I am stiring a strongly acidic or alkali solution in which case you should use PTFE or
glass

the grade of stainless is important. some of the junky stainless is 304 which is no where near as good as 316 for chemistry applications. i have seen
cheap spatulas react violently with nitric acid and produce Cu2+ colouration, but they are supposed to be stainless steel. such is life when we want
to pay $1 for a good quality tool, and the chinese are happy to supply at that pricepoint.

The only problems I've had with our steel spatulas is when some twit of a student uses them to stir a solution of copper
nitrate/acetate/chloride/sulphate and can't figure out why it suddenly looks so pretty.
Please remember: "Filtrate" is not a verb.
