Can we buy stainless steel cups without 304&316 symbols?(two)

Some friends will definitely say that if this is the case, I can claim compensation from the merchant if I find such a problem after purchasing the water cup.But in fact, in addition to the simple method of testing 304 stainless steel with magnets mentioned by editor before, it is difficult for individuals to test whether the water cup material is qualified by other means if a very strict test report is required.Of course, if those professional fighters can do this, but the supplier will also explain that the 316 stainless steel marked at the bottom is just the bottom, and does not indicate that the material of other parts is 316 stainless steel, which is not very wordless. I have experienced this situation myself.

Of course, the water cup without any symbol at the bottom will be more likely to cut corners.There are no hard rules for stainless steel water cups, but there are hard rules for plastic water cups in national and international industries.If the bottom mark of a plastic water cup is wrong, missing, inaccurate, unclear and fuzzy, it is not allowed.

It seems that the friends have met with unsolvable problems.In fact, there are other ways to judge whether the material of this cup is up to standard, that is, when purchasing this cup, pay more attention to check whether this cup has been tested by an authoritative testing agency.Whether the test results meet the requirements of national standards, American standards and European standards.If you see the display of the quality inspection report from the manufacturer, you can buy this water cup with confidence, even if there is no symbol of 304 stainless steel or 316 stainless steel at the bottom of this stainless steel water cup.

Finally, I would like to emphasize the way of magnet testing.Since the exposure of small articles increased in this way, many poor manufacturers can avoid the problem of magnetization when purchasing materials, and also constantly explain that it is because of the magnetism of materials in production and processing.Because 304 stainless steel and 316 stainless steel present weak magnetism, while 201 stainless steel and other stainless steels present strong magnetism.But now some factories will purchase 201 stainless steel with weak magnetic field to produce water cups. Please refer to the product test report.

Speaking of this, many colleagues, including Xiaobian, have shared with you their intention to focus on the safety of materials.Therefore, many such sharing methods have formed the effect of "three people make a tiger", causing people to have doubts about the water cup without symbol.
