How to identify the quality of stainless steel water cups

1. Understand the material types of stainless steel water cups

The materials of stainless steel water cups are generally divided into three types: ferritic stainless steel, austenitic stainless steel and martensitic stainless steel. Among them, austenitic stainless steel has the strongest corrosion resistance and is the most commonly used material. Therefore, it is recommended to choose austenitic stainless steel water cup when purchasing.

2. Understand the composition of stainless steel water cups
The composition of stainless steel water cups has a great impact on the quality of the product. Stainless steel water bottles with higher composition have better corrosion resistance and durability. Therefore, when purchasing stainless steel water cups, it is recommended to choose 18/8 or 18/10 stainless steel water cups.

3. Understand the manufacturing process of stainless steel water cups
The manufacturing process of stainless steel water cups will also affect the quality. A good stainless steel water cup adopts a process of separating the inner tank and outer shell to ensure that the inner tank can be cleaned smoothly. At the same time, a good stainless steel water cup will handle the welding joint to ensure that it is not dripping and dirty, and to avoid bacterial residue.

4. How to identify the quality of stainless steel water cups1. Check the shelf life: Good stainless steel water bottles generally have a warranty period, which is the manufacturer’s confidence in the quality of their products.

2. Observe the surface: A good stainless steel water bottle has a smooth surface, no scratches or oxidation, no rust spots, and a uniform color.

3. Smell: Open the lid of the stainless steel water cup and smell if there is any peculiar smell inside. A good stainless steel water bottle will remove odor during the production process.

4. Measure the weight: For stainless steel water bottles of the same volume, the heavier the weight, the better the quality.

5. Water drip test: Pour a few drops of water into the stainless steel water cup. If the water quickly forms droplets and slides off, it means that the surface of the stainless steel water cup is well treated and of good quality.

5. How to maintain stainless steel water cups
1. Regular cleaning: It is recommended to clean it in time after each use to avoid leaving impurities and bacteria.

2. Avoid scratching: Avoid using steel balls and other items for cleaning to avoid scratching the stainless steel surface.

3. Prevent collisions: Be careful when using and avoid collisions.

【in conclusion】

When choosing a good stainless steel water bottle, you need to pay attention to many aspects, including material type, composition, and production process. At the same time, proper maintenance is also required after purchase, which can not only extend the service life, but also ensure the hygiene and safety of the water cup.
