dublex ss has 22% or more but ss has 18%cr or less
the main difference is that duplex is a mix of a ferrite / austenite structure approx 50%/50%, and so the name "duplex" while stainless steel has just one structure, for example the 18/10 is an austenitic.
There's no difference, cause duplex is a type of Stainless Steel, as so ferritic,austenitic,martensitic.
When an alloy of steel contains more than approximately 10 ½% Chromium it can be classified as a stainless steel. There are several clasifications of stainless steel with varying propertys Martensitic, Ferritic, Austenitic and Duplex.
While stainless steel is an alloy of steel, the primary difference between stainless steel and other steels is that the stainless steels have a high percentage (about 10% or even more) of the element chromium in them.
a tin plate is tin and a plate, and stainless steel is stainless steel.
Satin is a finish on the stainless steel which changes its look.
Well, the answer lies in the question; by saying 'real' stainless steel, you are implying that there are fake metals which go under the name 'stainless steel', thus the difference is that the stainless steel in refigerators is actually stainless steel, and the fake stainless steel is not...thus your question is answered...
what is difference between mild steel and stainless steel
It was found that sound velocity in duplex stainless steel increases with aging time. This is progress of thermal aging.
nothing because it is steel is steel
Stainless steel is an alloy with at least 10.5 percent chromium. Zinc steel is coated with zinc.
stainless and silver is defferentbecouse silver is a colour and stainless are stains
stainless is steel. aluminum is aluminum
