Which type of stainless steel do basins, bowls, and trays belong to?

The type of stainless steel that basins, bowls, and trays belong to is known for its excellent corrosion resistance, durability, and formability, making it suitable for medical and surgical environments. The 300 series stainless steel, particularly 304 and 316 grades, is widely used in the manufacturing of medical instruments and equipment because of its non-reactive properties and overall strength.

The composition of the 300 series includes a higher nickel content, which enhances the steel's resistance to corrosion and makes it ideal for applications where hygiene is paramount, such as in sterile processing. This type of stainless steel can withstand high temperatures and harsh cleaning chemicals, which is essential for maintaining the sterility of instruments.

On the other hand, the 200 series, while also a stainless steel, has a lower nickel content and is generally less corrosion-resistant than the 300 series. The 400 series is primarily known for being magnetic and is commonly used in applications where corrosion resistance is less critical. The 500 series is not typically associated with the production of kitchen or medical equipment. Thus, the 300 series stands out as the correct choice for basins, bowls, and trays used in sterile processing.
