Cold Rolled Mirror 2B 0.6mm Grade SUS 304 420 Stainless Steel Coil
Introduction to 420 stainless steel: Standard: AISI, ASTM Features and applications: 420 stainless steel, 420 stainless steel is 420 "cutting grade" martensitic steel, similar to Brinell high chromium steel, the earliest stainless steel. 420 has certain wear resistance and corrosion resistance, high hardness, the price is higher in stainless steel ball The lower one is suitable for the working environment of stainless steel. The .420 stainless steel is suitable for all kinds of precision machinery, bearings, electrical, equipment, instruments, meters, transportation tools, household appliances, etc. It is mostly used to manufacture parts resistant to atmospheric, water vapor, water and oxidizing acids.
CHEMICAL COMPOSITION
Cold Rolled Stainless Steel coil :
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.
stainless steel coil surface appearance and the possibility of diversification:
Good corrosion resistance, longer durability than ordinary steel
High strength, so the possibility of using the thin plate is big
High temperature oxidation and strength, so it can resist fire
Normal temperature processing, that is, easy to plastic processing
Because it is not necessary to surface treatment, so simple, easy to maintain, clean, high finish, good welding performance
