201 / 304 Stainless Steel Tank Laser Cutting Holes For Filtering
Water
Type 201 Stainless Steel is an austenitic chromium-nickel-manganese
stainless steel which was developed to conserve nickel. Type 201 is
a lower cost alternative to conventional Cr-Ni stainless steels
such as 301 and 304. Nickel is replaced by additions of manganese
and nitrogen. It is non-hardenable by thermal treatment, but may be
cold worked to high tensile strengths. Type 201 is essentially
nonmagnetic in the annealed condition and becomes magnetic when
cold worked. Type 201 can be substituted for Type 301 in many
applications.

2. How to Choose Good Stainless Steel Tank
The stainless steel sink plate thickness is best chosen between
0.8–1.2mm. Within this thickness, 304# material stainless steel is
chosen to make the tank tough enough to avoid damage to all types
of porcelain vessels due to impact. The easiest way is to press the
surface of the sink slightly. If you press it down, it means that
the material is thin.
Thickness:
The thin, light and thin edge not only allows the sink's maximum
washing space and minimum appearance size to be unified, but the
water splashing out of the sink can easily be wiped into the sink.
weight:
Stainless steel is a kind of ferroalloy. The specific gravity of
steel is 7.87. Nickel and chromium heavy metals are added inside.
The proportion of these metals is greater than steel, so the weight
is heavy. Counterfeit and inferior stainless steel, such as chrome
plated steel, is lighter.
Process:
Stainless steel sinks are welded and integrally formed. The welding
method is divided into two types. One is the welding of the pot and
the panel welded together. The advantage is that the appearance is
beautiful. After the strict treatment, the welding mouth is not
easy to be found. The surface of the sink is straight and smooth.
The disadvantage is that some consumers Suspected of its
sturdiness. In fact, the current welding technology mainly includes
sub-arc welding and the most advanced numerically controlled
resistance welding, and the quality has passed. The other is the
butt welding of two single-pot butt welding. The advantage is that
the pot and the panel are one-piece stretched and sturdy. Durable,
its disadvantage is that it is easy to see the welding marks, and
the flatness is slightly poor. One-step molding is currently a more
advanced and popular manufacturing process, but the production
process is difficult, and the overall thickness of the formed water
tank is uneven, thin, mostly about 0.7mm, and a good thickness of
the basin should be 0.8-1.0 Mm, not the thicker the better, the
thicker the material sink is too bulky, it will easily deform the
cabinet, it will also damage the utensils, 0.8-1.0mm is the best
thickness, long life, utensils will be safe.
Depth:
The height of the sink, which is suitable for domestic use, is
180mm or more. Its advantage is large capacity and splash-proof.
