304 stainless steel is a common material in stainless steel, the
density of 7.93 g/cm, also known as 18/8 stainless steel.High
temperature resistance 800℃, with good processing performance, high
toughness, widely used in the industry and furniture decoration
industry and food and medical industry.

Cold rolled: Hot rolled coil is used as raw material, and the oxide
skin is removed by pickling. The product is rolled coil. The cold
work hardening caused by continuous cold deformation makes the
strength, hardness and toughness and plasticity of rolled coil
increase, so the stamping performance will deteriorate and can only
be used for parts with simple deformation. Rolled coil can be used
as raw material for hot galvanizing plant because annealing lines
are set up in hot galvanizing units. The weight of rolled coil is
generally 6-13.5 tons. The hot rolled pickling coil is rolled
continuously at room temperature. The inner diameter is 610 mm.
Cold Rolled Stainless Steel Sheet / Plate:
a. Stretch good, toughness, but the price is more expensive;
b. Cold rolling processing surface without oxide skin, good
quality;
c. Cold rolling is generally used in the production of strip, the
rolling speed is high;
d. Cold rolling than the thickness of the high precision.
Mechanical properties, surface and so on in the hot rolling;
e. Cold-rolled steel coil due to a certain degree of work
hardening, low toughness, but can achieve better yield ratio, used
for cold-formed spring and other parts;
f. Cold coil yield point closer to the tensile strength, so the use
of risk in the process of no predictability, when the load exceeds
the allowable load prone to accidents
g. The surface of the cold rolled steel coil without plating is
gray.
h. Cold rolled steel plate surface smoothness is higher than the
hot rolled steel coil.
