hardness of martensite is greater than bionite and fine pearlite.
Martensite transformation begins when austenite is cooled below a certain critical temperature, called the matrensite start temperature. As we go below the tmartensite start temperature, more and more martensite forms and complete transformation occurs only at a temperature called martensire finish temp. Formation of martensite require that the austenite phase must be cooled rapidly.
Ferritic and austenitic stainless steels are not heat treatable since "heat treatable" is taken to mean that martensite may be made to form with relative ease upon quenching austenite from an elevated temperature. For ferritic stainless steels, austenite does not form upon heating, and, therefore, the austenite-to-martensite transformation is not possible. For austenitic stainless steels, the austenite phase field extends to such low temperatures that the martensitic transformation does not occur.
no
I think these bins are formed by being formed around a mould.
Martensite
Carbon Steel - Martensite
Microscopically (what we can see through an electronic microscope), steel is seen in a shape of grains, particules, beans, but the submicroscopic strcture of steel is its crystalline structure: the ferrite is Cubic centred, austenite is cubic faced centred and martensite is like a parallelogram.

Stainless steel is not an element, but an alloy formed by the combining of carbon, iron, manganese, chromium, vanadium, tungsten, and other various elements.
There is stainless steel and there is magnaized stainless steel but you can not make regular stainless steel magnetic
steel is steel and there is nothing you can do about it even if it is stainless steel or it i not stainless steel it will rust
