Stainless Steel 304 VS 316 Material for stainless steel tumblers

According to the survey, the per capital holding stainless steel water bottle is around 0.68pcs. This is huge data. Good metal water bottle will make effect our health.

Also replacing disposable plastic counterparts with a touch of elegance and a whole lot of practicality, these vessels have become an essential part of our daily lives. But beneath their sleek exteriors lies a symphony of factors that make them more than just a means to quench thirst.

Even some merchants have introduced the use of their own cups to buy coffee, you can reduce some fees, such as Starbucks.

Do you know the material and different raw material cost?

Stainless steel 304 and 316 are both austenitic stainless water bottle and safe. While the difference is that 316 adds 2% more molybdenum. In this way, the corrosion resistance of 316, especially the resistance to chloride corrosion, is better than that of 304.

Below list is China 304 & 316 each tone material RMB cost. 316 is higher 304 almost 57%. So this will effect the unite water bottle cost.

To compare what is a 304 & 316 stainless steel cups function?

304 stainless steel tumbler (18/8) is the undisputed maestro, gracing the majority of water bottles and tumblers.

Durability: It can withstand bumps, drops, and ensuring your companion lasts through countless adventures. Of course power coating is more durability than paint coating.

Safety: Free from harmful chemicals like BPA, it keeps your precious fluids pure and worry-free.

Temperature Control: Whether you crave icy refreshment or soothing warmth, 304 stainless steel tumbler maintains the ideal temperature for more than 8 hours.

Ease of Maintenance: Non-porous and odor-resistant, cleaning becomes a breeze, leaving you more time for the important things in life.

Also 304 has more benefit and is a versatile stainless steel material. It is also relatively good in terms of high temperature resistance, and the general use temperature limit is less than 650°C. 304 stainless steel has excellent stainless corrosion resistance and good intergranular corrosion resistance.

In addition to the uses of 304, 316 stainless steel cups also include 18Cr-12Ni-2.5Mo. Due to the addition of Mo, its corrosion resistance, atmospheric corrosion resistance and high temperature strength are particularly good, and can be used under harsh conditions; work hardening Excellent (non-magnetic).

Comparison of the chemical composition of additives in SUS304 and SUS316

From the below list, we can be more clearly to see the different.

Chemical composition:?SUS304 /SUS316

Carbon C:≤0.08 /≤0.08

Silicon Si :≤1.00/?≤1.00

Manganese Mn:?≤2.00/?≤2.00

Sulfur S :≤0.03/?≤0.03

Phosphorus P : ≤0.045/?≤0.045

Chromium Cr: 18.00～20.00/?16.00～18.00

Nickel Ni : 8.00～10.50/?10.00～14.00

Molybdenum (Mo):NA/?2.00～3.00

As can be seen from the table above, the difference between SUS304 stainless steel and SUS316 stainless steel is mainly in the content of nickel and chromium, and SUS316 stainless steel adds corrosion-resistant molybdenum element. The corrosion resistance of 316 stainless steel is better than that of SUS304 stainless steel, and it can maintain its corrosion resistance without special maintenance and can be used in complex environments. Can be used to hold boiled water, juice, drinks, etc.

316 and 304 are suitable for what kind of places?

304 stainless steel is a common stainless steel material, mainly used in the production of household appliances, kitchenware, tableware, sinks and so on. It consists mainly of 18% chromium and 8% nickel. Therefore, 304 stainless steel has good oxidation resistance and corrosion resistance, good high temperature resistance and low temperature resistance, and is suitable for indoor and low temperature environments.?

316 stainless steel is a high-end stainless steel material, mainly used in the production of medical equipment, Marine equipment, chemical equipment, food processing equipment and so on. And 316 stainless steel oxidation resistance, corrosion resistance and wear resistance are better than 304 stainless steel, suitable for high temperature, high pressure and Marine environment and other harsh conditions.

304 vs 316: What Makes Them So Popular?

To sum up, 316 is indeed more environmentally friendly than 304. Personally, I think that for children's cups, you can choose 316 material. At the same time, you can choose 316 if you have special requirements for the liquid you hold. For most people, 304 can also meet our usual requirements. After all, 316 is more expensive. And from the query on Amazon, using the keyword "stainless steel mug 304/316", there are only 183 results for 316, but 100,00 results for 304. In the end, it all depends on your specific needs.
