Hot-rolled coil has relatively low strength, poor surface quality (low
oxidation/smoothness), but good plasticity, generally medium and
heavy plate, cold-rolled sheet: high strength, high hardness, high
surface finish, generally thin sheet, can be used as stamping With
the board.
Hot-rolled steel sheet, mechanical properties are far less than
cold processing, second only to forging, but with good toughness
and ductility
Heat Resistance :
Grade 430 resists oxidation in intermittent service up to 870°C and
to 815°C in continuous service. This grade may become brittle at
room temperature after prolonged heating in the 400-600°C range.
This effect can be eliminated by annealing.

Welding
Excellent weldability by all standard fusion and resistance
methods, both with and without filler metals. Heavy welded sections
in Grade 201 require post-weld annealing for maximum corrosion
resistance.
Machining
Stainless steel tends to work harden if machined too quickly. For
this reason low speeds and constant feed rates are recommended.
