AISI 302 303 304 Stainless Steel Plate Sheet Cold Rolled 0.15mm
Thick No.4
What is the difference between 302 and 304 stainless steel?
Like grade 304, alloy 302 is an austenitic stainless steel alloy.
Therefore, they share certain elements, which is what gives them
the same austenitic microstructure.
However, they fall into different grades solely because of the
modification of the constitution of the elements.
For instance, the content of carbon in grade 302 is a max of 0.15%
carbon, with a max value of 0.8% in stainless steel alloy 304.
The lower content of carbon in austenitic steel grade 304
effectively lowers the risk of carbide precipitation, which occurs
in alloys that have a higher percentage of carbon in their alloys.
The main benefit of using grade 302 is that this particular
stainless steel alloy demonstrates good resistance to solvents,
acids as well as resistance to several chemicals.
303 Stainless Steel Material Data Sheet
AISI 303 is a non magnetic austenitic stainless steel and a
modified version of Alloy 304 with addition of Sulphur to improve
machinability.
It has improved chemistry as compared to 18/8 Stainless Steel to
display extra machinining performance maintaining good mechanical &
corrosion properties.
Stainless Steel 303 offers excellant toughness though sulphur
addition imparts cutback to some limit.
NO.4 Polish Stainless Steel sheets
No.4 finish is duller than the other common finishes, 2B and BA and
is generally used where lower reflectivity or gloss is required and
where welds and other fabrication marks are to be refinished to
match the original surface.
This is not possible with 2B and difficult with BA.
A 'No 4' surface finish stainless steel sheet or coil is produced
by cutting the surface with abrasive belts to remove a very small amount of metal without
affecting its thickness.

Stainless steel plates are widely used in below fields:
1.Beams, columns, platforms and supports in water treatment
processing plants, pulp and paper manufacture,
nuclear, biomass, chemical, pharmaceutical as well as the food and
beverage industries.
2.Primary beams and columns, pins, barriers, railings, cable
sheathing and expansion joints in bridges.
3.Seawalls, piers and other coastal structures.
4.Reinforcing bar in concrete structures.
5.Curtain walling, roofing, canopies, tunnel lining.
6.Support systems for curtain walling, masonry, tunnel lining, etc.
7.Security barriers, hand railings, street furniture.
8.Fasteners and anchoring systems in wood, stone, masonry or rock.
9.Structural members and fasteners in swimming pool buildings
(special precautions should be taken in structural
components in swimming pool atmospheres due to the risk of stress
corrosion cracking).
10.Explosion and impact resistant structures such as security
walls, gates or bollards.
11.Fire and explosion-resistant walls, cable ladders and walkways
on offshore platforms.



Packaging: According to customers' needs, use wrapping paper.
If the transportation period exceeds 10 days or encounters special
climate, we will use waterproof packaging and add plastic film to
prevent moisture, water and rust.
Loading: We use the wooden pallet,triangular wood to fix the coil,and the
steel wire rope to hold on the both side. That can prevent from the
crush injury effectively.
