Q:Comparison of three properties of aluminium plate, stainless steel plate and cold rolled plate?
Aluminum sheet material is light, easy to shape, good coloring;
Q:What's the thinnest stainless steel plate in China?
Stainless steel hot rolled plates are rolled into relatively thin steel sheets at higher temperatures, and cold-rolled steel sheets are rolled at room temperature. Usually the first hot rolling, and then cold rolling. If the steel plate is thicker, it can only be rolled by hot rolling, then rolled into a thinner plate and then cold rolled. Hot-rolled steel sheet is divided into thick plate (thickness greater than 4mm) and sheet (thickness of 0.35~4mm) two kinds; cold-rolled steel sheet only (thickness of 0.2~4mm) one.
Q:What is the difference between stainless steel 304 and stainless steel 202?
202 stainless steel is one of the 200 series stainless steel, the national standard model is 1Cr18Mn8Ni5N. 200 series stainless steel is low nickel, high manganese stainless steel, nickel content, manganese content of about 8%, is a nickel type stainless steel.
Q:What is 3042B stainless steel?
2B: the fog surface; after cold rolling, after heat treatment and acid washing, the finishing surface is made to be a fair light. As the surface is smooth, easy to re grinding, make the surface more bright, wide range of uses, such as tableware, building materials, etc.. Surface treatment with improved mechanical properties almost meets all uses.Stainless steel can be divided into Cr series (400 Series), Cr - Ni series (300 Series), Cr - Mn - Ni (200 Series), Heat-Resisting Chromium Alloy Steel (500 Series) and precipitation hardening system (600 series).
Q:The difference between 304J1 stainless steel plate and 304 stainless steel plate
304J1 is a copper containing material of 304. It is mainly used in deep processing and also belongs to the series of nickel. By the Japanese on the basis of the successful development of American Standard 304.
Q:Why do drill holes burn on stainless steel plates? What's the best way to drill them?
The cutting fluid is made of concentrated emulsions. Commonly used stainless steel drills are: high cobalt bit (M35 bit, M42 bit), in which the M42 bit is the most cost-effective, and carbide drills are also available.
Q:What does stainless steel plate mean?
The corrosion resistance of stainless steel mainly depends on its alloy composition (chromium, nickel, titanium, silicon, aluminum, manganese, etc.) and the internal structure of the alloy, and the main role is chromium. Chromium has high chemical stability, can form a passive film on the steel surface, so that the metal is isolated from the outside, protect the steel plate from oxidation and increase the corrosion resistance of the steel plate. When the passive film is destroyed, the corrosion resistance will decrease.
Q:What's the difference between 304 stainless steel and 301 stainless steel?
301, compared with 304 steel material, C content is much, Cr and Ni content is little, cold processing tensile strength and hardness increased, without magnetism, but after cold processing has magnetism
Q:What drill can drill stainless steel?
Drilling stainless steel materials, there are two main domestic products: high-speed steel bit, carbide drill. Carbide hollow drill is of high toughness and good wear resistance. It is recommended that you use this material. The price depends on the specifications you need.
Q:What is the stainless steel grid board? What areas of stainless steel mesh panels are used in?
Lattice plate of stainless steel steel has strong corrosion resistance, anti-corrosion effect was significantly higher than that of hot dip galvanized steel plate, but the cost is higher, stainless steel grid board is widely used in municipal, environmental protection, steel structure, boiler, desulfurization and denitrification projects, procurement of stainless steel grid plate, Changzhou Gemeirui steel grid plate.
