Stainless steel strappingThe company's losses are expanding rapidly

the investment in fixed assets in the iron and steel industry was 303.5 billion yuan

(VI) the growth rate of fixed asset investment in the iron and steel industry dropped significantly. From 2013 to June,Quotation sheet of stainless steel pipe, a year-on-year increase of 3%,Hot rolled stainless steel strip, of which the investment in ferrous metal smelting and rolling was 235.6 billion yuan, a year-on-year increase of 3%, down 1 percentage point from the same period in 2012; The investment in ferrous metal mining and dressing was 67.9 billion yuan, a year-on-year increase of 8%, and the growth rate fell sharply by 15 percentage points.

Corrosion resistance most stainless steel products require good corrosion resistance. Stainless steel pipe is similar to class I and II tableware, kitchen, water heater, water dispenser, etc. Some foreign businessmen also test the corrosion resistance of products: use NaCl aqueous solution to warm to boiling. After a period of time, the solution is to drain, wash and dry, and determine the weight loss to determine the degree of corrosion.

.Good ductility, used for forming products. It can also be machined to harden rapidly. Good weldability. Wear resistance and fatigue strength are better than stainless steel.

The best choice is also frequently launched in the market. If you want to buy a stainless steel water supply pipe with quality assurance, how should you choose?

.Check the clamping forming effect after each clamping, and there shall be no clamping in place or serious depression of pipe clamping. According to visual inspection, the pipe fitting end and the pipe are tightly bonded. The smaller the diameter of the diamond edge of the pipe fitting above DN25 is slightly smaller than the outer diameter of the pipe, ranging from 0.1-2mm. The larger the pipe diameter, the greater the difference.

300 series & mdash; Chromium nickel austenitic stainless steel.

In polluted air (such as atmosphere containing a large amount of sulfide, carbon oxide and nitrogen oxide), acetic acid liquid points will be formed, pitting, corrosion or wear. Stainless steel is also one of the high-strength materials in metal materials for construction. Because stainless steel has good corrosion resistance, it can ensure that the structural components can maintain the integrity of engineering design. Chromium containing stainless steel also integrates mechanical strength and high extensibility and is easy to wear The processing and manufacturing of parts can be full

While China's exported steel pipes are frequently subject to foreign anti-dumping and countervailing investigations, imported steel pipes are also constantly impacting domestic steel enterprises.

where.Today Xiaobian can help you. If you want to choose high-quality stainless steel pipe water supply pipe, you can choose this: choose the material of stainless steel pipe water supply pipe.

　　·Sewage treatment system.

Check the clamping forming effect after each clamping, and there shall be no clamping in place or serious depression of pipe clamping. According to visual inspection, the pipe fitting end and the pipe are tightly bonded. The smaller the diameter of the diamond edge of the pipe fitting above DN25 is slightly smaller than the outer diameter of the pipe, ranging from 0.1-2mm. The larger the pipe diameter, the greater the difference.

. 18%), which is better than l and 317L in most environments.

Create brilliance.During butt backing, in order to prevent the back of the underlying weld bead from being oxidized, the back also needs to be protected by gas.

Chloride ions exist in the service environment. Chloride ions exist widely, such as salt, sweat, sea water, sea breeze, soil, floating rust of iron foam and so on. Stainless steel corrodes rapidly in the presence of chloride ions,How much is stainless steel, even more than ordinary low carbon steel. Therefore, there are requirements for the service environment of stainless steel, and it is necessary to remove dust frequently and keep it clean and dry. (in this way, we can give him a & ldquo; improper use & rdquo;) there is an example in the United States: an enterprise uses an oak container to contain a solution containing chloride ions. The container has been used for nearly 100 years. The ninetieth generation of the last century plans to replace it. Because the oak material is not modern enough, the container leaks due to corrosion 16 days after it is replaced with stainless steel.

500 Series & mdash; Heat resistant chromium alloy steel.

.Cold rolled oriented silicon steel strip consists of nominal thickness (expanded by 100 times) + code G: ordinary material, P: high oriented material + guaranteed iron loss value (the value after expanding the iron loss value when the frequency is 50Hz and the large magnetic flux density is 7T by 100 times). For example, 30g130 indicates that the thickness is 0.3mm and the guaranteed value of iron loss is ≤ 3 cold rolled oriented silicon steel strip. Liaocheng Suntory stainless steel provides electroplated tin plate and hot-dip galvanized plate: electroplated tin plate, electroplated tin sheet and steel strip, also known as tinplate. The surface of the steel plate (belt) is plated with tin, which has good corrosion resistance. In addition, it can be used as packaging material for cans, inner and outer sheath of cables, instrument and telecommunication parts flashlight and other hardware.
