Q:Will 304 stainless steel and 301 stainless steel What is the difference?

1, specifications: commonly used stainless steel sheet is divided into 201 and 304 two models, the actual composition is different, 304 quality better, but the price is expensive, 201 worse. 304 for the import of stainless steel, 201 for the domestic stainless steel plate. 2, 201 composition of 17Cr-4.5Ni-6Mn-N, is the section of Ni steel, 301 steel alternative steel. After cold processing with magnetic, for railway vehicles. 3, 304 composition of 18Cr-9Ni, is the most widely used stainless steel, heat-resistant steel. For food production equipment, the former chemical equipment, nuclear energy and so on. 4, 201 is a high manganese content, the surface is very bright with dark black, high manganese content is easy to rust. 304 chrome more, the surface showing matte, no rust. Two put together there is a comparison. The most important thing is the corrosion resistance of different, 201 corrosion resistance is poor, so the price will be much cheaper. And because 201 nickel low, so the price is lower than 304, so corrosion resistance is not as good as 304. 5, 201 and 304 is the difference between the nickel-containing problem. And the price of 304 are now more expensive, generally close to 50000 a ton, but at least 304 can guarantee that the use of the process will not rust. (Can be used to do the experiment) 6, stainless steel is not easy to rust because the surface of the steel body to form chromium-rich oxide can protect the body, 201 material is high manganese stainless steel 304 hardness higher carbon low nickel. 7, the composition of different (mainly from carbon, manganese, nickel, chromium and other aspects to distinguish between 201 and 304 stainless steel) Steel (C) silicon (Si) manganese (Mn) phosphorus (P) sulfur (S) chromium (Cr) nickel (Ni) molybdenum (Mo) copper (Cu) AISI (304) ≤0.08 ≤1.00 ≤2.00 ≤0.045 ≤0.03 18-20 8-10 AISI (201) ≤0.15 ≤1.00 5.5-7.5 ≤0.05 ≤0.03 16-18 3.5-5.5

Q:What kind of domestic brand plate frame good?

Eyes are their own, love the eyes is very necessary, especially after myopia, do not just say where to see where the glasses discount quickly ran with glasses, but the quality of the glasses off the eye damage is very large , The importance of the frame can not be ignored. So when the glasses with the choice of good glasses glasses is the most critical. Now the glasses are better brands are the island, Daming, the United States pupil - Johnson & Johnson, Hai Chang, snow and so on, these are the brand network MAIGOO 2017 top ten glasses brand, you can go to see the above details. Or that sentence, the eyes are their own, not for a moment of cheap on the casual with the pair of glasses, be sure to choose a good brand.

Q:2.2 meters high 3.5 meters deep 30, no hardware, probably the following, the budget probably how much!

I was selling the brand name of the overall kitchen cabinet, according to the figure: If the overall 450 yuan / square: 450X7.7 = 3465 yuan, If the expansion of the calculation: 18 PCT side board 2.2X0.3X8 = 5.28 18% baffle 2.2X0.3X2 = 1.32 18 layers 3.5x0.3X6 = 6.3 5 PCT backplane 2.2X3.5X1 = 7.7 Material Amount: 18 PCT = 220 yuan / square X12.9 = 2838 yuan 5% = 135 yuan / square X7.7 = 1039.5 yuan A total of 3877.5 yuan Count all the good material,

Q:Solid wood furniture and panel furniture which pollution is small?

Popular, solid wood furniture is certainly a small pollution, but the market is full of a lot of parallel imports of solid wood furniture, such as solid wood paste, obviously the middle of the particleboard, posted a bark on the outside that is solid wood furniture, furniture and sheet furniture in my It seems there is no difference, choose a good solid wood furniture from the material, technology point of view. General people think that solid wood furniture is certainly all solid wood, but simply not, so when you buy furniture to ask the material, all parts of the material to ask, there is a desktop is solid wood, table legs are not, some desktop is good Wood, table legs with parallel wood, but the price tag is good wood price. Anyway, if you are very stressed that pollution is small, you will see manufacturers have no 10 ring certification, which is the most authoritative environmental certification, of course, people have money to buy another matter on the matter. You'd better buy a brand name, so safe, because to tell the truth, many small workshops which produce furniture, and then to the supermarkets to pay a long lease, transformed into a good furniture, and is completely deceptive. There is to shop around!
