1. What is the difference between 34 stainless steel and 316 stainless steel?
1. The chemical composition is different: 34 does not add molybdenum, while 316 does.
2. Different corrosion resistance: 34 contains only 9% nickel, while 316 contains 12% nickel, so the corrosion resistance of 34 is even worse.
3. Different properties: 34 has better corrosion resistance, acid resistance and alkali resistance, while 316 has better chloride corrosion resistance and heat resistance because of adding molybdenum.
4. Different scope of application: 34 is widely used to make pots and pans, while 316 is widely used in food industry, medical industry, watch industry and so on.
5. Different prices: Because 316 is food grade and has better corrosion resistance, the price of 316 will be more expensive than that of 34.
2. How to distinguish between 34 stainless steel and 316 stainless steel tableware
1. If you look at 34 stainless steel and 316 stainless steel with naked eyes, you can't see any difference, so many merchants sell 34 stainless steel as 316 for their own benefit, but the price difference between them is quite big. Because 316 belongs to food grade and has better corrosion resistance, the price of 316 will be more expensive than 34. If you spend 316 yuan, but buy back 34 stainless steel tableware, it means you have wasted money.
2. Because the chemical composition of 34 and 316 is different, professional stainless steel potion can be used to distinguish them. After dropping liquid medicine on stainless steel, the surface of 34 material is generally a little red, while that of 316 material is black.
3, if there is no professional potion, you can also use magnets to test and distinguish. If stainless steel belongs to 34 material, it cannot be attracted by magnets. But the accuracy of this method will be relatively low.
4. In fact, if it is just for home use, it is not necessary to choose 316 material, because the characteristics of 34 are completely in line with household standards, so as to avoid buying only 34 products at the price of 316 material.
