How about 304 vacuum stainless steel insulating cup?
In fact, for stainless steel utensils, the state has a standard: stainless steel insulating cup industry standard, which clearly states that the minimum material standard is 304 # stainless steel (austenitic stainless steel). 304 vacuum stainless steel insulating cup is not rusty, cost-effective, so it is selected as the standard material of stainless steel utensils. Of course 201 stainless steel can also be made into cups, but easy to rust; 316 stainless steel can also be made into cups, but the price is higher. Therefore, 304 vacuum stainless steel insulating cup has the highest cost performance ratio.
How to choose 304 vacuum stainless steel insulating cup?
Through the above understanding, the choice of stainless steel insulating cup should be different from the material, buy the cup when you need to see the instructions, see if the material is 304 stainless steel. Next is to choose the thermal insulation performance, to see if there is any obvious knock or defect, and then pour into a cup of hot water, horizontal on the table, to see if there is water penetration, 3 to 5 minutes later, hold the cup body with your hand, feel if there is no obvious temperature; if there is no water seepage, no defect, no obvious temperature, that means this. The insulating cup is a real vacuum stainless steel insulating cup.
