Why is a stainless steel thermos made entirely of 201 stainless steel not suitable for use as a hot water drinking cup?

Although 201 stainless steel is widely used in some stainless steel products, using 201 stainless steel exclusively in the production of stainless steel thermoses is not an ideal choice. http://www.umbottle.com/ProductsDetail-VB-10413.htmlHere are detailed reasons why a stainless steel thermos made entirely of 201 stainless steel is not suitable for use as a hot water drinking cup:

Higher manganese content: 201 stainless steel contains a higher proportion of manganese, and in the case of hot water consumption, manganese may dissolve into the water. http://www.umbottle.com/ProductsDetail-VB-10413.htmlProlonged intake of excessive manganese may pose potential health risks, making it unsuitable for use in the production of hot water drinking cups.

Relatively poor corrosion resistance: Compared to other stainless steel grades, 201 stainless steel has relatively poor corrosion resistance. http://www.umbottle.com/ProductsDetail-VB-10413.htmlHot water may accelerate corrosion on its surface, leading to the generation of contaminants inside the thermos, affecting the quality of the water.

Not suitable for high-temperature environments: The temperature range for using 201 stainless steel is relatively low and is not suitable for long-term storage or insulation of hot water. http://www.umbottle.com/ProductsDetail-VB-10413.htmlIn high-temperature environments, it may cause changes in stainless steel, affecting the performance of the thermos.

Lower nickel content: 201 stainless steel has a relatively low nickel content, and nickel may cause allergic reactions in some individuals. http://www.umbottle.com/ProductsDetail-VB-10413.htmlAlthough not everyone is allergic to nickel, it is more suitable to choose stainless steel grades with higher nickel content to cater to a broader population.

Does not meet high standards: Hot water drinking cups typically require higher material standards to ensure the safety and quality of the water. 201 stainless steel may not necessarily meet these high standards, http://www.umbottle.com/ProductsDetail-VB-10413.htmlso it is more appropriate to choose higher-grade stainless steel, such as 304 or 316, when producing hot water drinking cups.

In conclusion, a stainless steel thermos made entirely of 201 stainless steel is not suitable for use as a hot water drinking cup. When choosing a stainless steel thermos, consumers should opt for products made from food-grade, http://www.umbottle.com/ProductsDetail-VB-10413.htmlhigh-quality stainless steel to ensure safety and durability. Additionally, following the manufacturer's usage and maintenance guidelines can help extend the life of the stainless steel thermos.
