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:Computer tables, two kinds of sheet: particleboard / melamine board MDF / fiber board which is better material?
MDF is a plant wood fiber as the main raw material, by the hot mill, pavement, hot forming and other processes made.
MDF surface smooth and smooth, fine material, stable performance, the edge of a solid, and the decorative surface of the board is good. But the density of the board is less tolerant of moisture, and in contrast, the density of the clamping force of the board less than the particle board, screw tightening if the loose, because the density of the board is not high, it is difficult to fix.
Particleboard is made of natural wood crushed into pellets, and then pressed by the adhesive, because the profile similar to honeycomb, so called particleboard, environmental protection coefficient is much higher than the density board. Many manufacturers produce furniture using particleboard, but also the main material of the cabinet. Particleboard surface is often rubbed with trimethylenediamine on both sides of the finish, the edge of the treatment and MDF appearance of the same, the use of special connection assembly, removable.
So recommend particleboard.
Q:Plate related knowledge
Q:Will the 2017 plate 10 brand quality how?
Ranked by quality, the New Zealand Pavilion is a well-deserved first. New Zealand Chilean plate benefited from New Zealand's unique island climate, and in the case of the ever-decreasing natural forests in the world, New Zealand Wood has grown well as a sustainable renewable resource. Zhige plate selection of trunk high, light color, solid wood, very suitable for furniture manufacturing and a variety of decorative wood applications.
Q:Villa special plate selection which brand plate?
Landlord, decoration villa ah, it should not be short of money, you can decorate the point, and now are more emphasis on decoration with environmental protection, so the landlord can find some environmental decoration company to choose and reference. My house before the house decoration, do the decoration is relatively high-end, then choose the decoration of the company, they have been known for a herbal home improvement, my home is where the choice of natural Thai ecological floor, which is A more environmentally friendly floor, the performance is very good, the price is not too expensive, the landlord can see!

Q:Aluminum alloy cutting method
General cut the formula is the total width of the outer frame minus 4 cm is equal to the extent of the frame up and down the slide; the total width of the shell minus 4 cents minus the two light business minus a hook enterprise divided by 2 equal to the upper and lower horizontal degree. This thing to find some information to learn. The The Find some content on the Internet about cutting down.

Q:How to buy plate formaldehyde climate chamber?
Buy formaldehyde climate box to focus on the following aspects:
1, to find professional R & D manufacturers to buy, more than a few comparison, assessment of comprehensive strength!
2, test box test parameters and test environment to meet the relevant standards and parameters!
3, combined with their own products, choose the appropriate test space!
4, formaldehyde climate test chamber should have a sophisticated test mode and improve the structure and security system!
