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.
