Austenite may contain carbon in any proportion up to about 2.2 It is non-magnetic, and, when preserved in the cold either by quenching or by the presence of manganese, nickel, &c., it has a very remarkable combination of great malleability with very marked hardness, though it is less hard than common carbon steel is when hardened, and probably less hard than martensite.
All these phenomena are parallel with those of 1 oo% carbon steel at this same critical point Ar l.
Its behaviour in this respect is thus the opposite of that of carbon steel.
The blade cuts the adhesive caulking compound around the windscreen using the specially hardened carbon steel blade.
The absorber construction material is usually carbon steel making the process less expensive in capital costs compared with wet scrubbers.
