Frosted stainless steel beltWhat are the functional characteristics and application scope

The product ground by the grinding belt.

Characteristics and application 347h austenitic stainless heat strength steel has good corrosion resistance,2507 stainless steel pipe, welding performance and heat strength performance. 347h stainless steel is used for large boiler superheater, reheater, steam pipeline and petrochemical heat exchanger pipe fittings.

.Only soluble paper or the combination of soluble paper and blocking plate is used for blocking ventilation protection (i.e. solid core welding wire + TIG + water-soluble paper)

Low temperature embrittlement --- in low temperature environment, the deformation energy is small. In the low temperature environment, the phenomenon that the elongation and area shrinkage decrease is called low temperature embrittlement. Most of them are produced on the body centered cubic structure of ferrite series.

.Corrosion test: the industrial corrosion-resistant steel pipes provided shall be tested for corrosion resistance according to the standard provisions or the corrosion agreed by both parties, and there shall be no tendency of intergranular corrosion.

201 series & mdash; Chromium nickel manganese austenitic stainless steel.

If packing is not required, it shall be indicated in the contract and will not bear the problem of scratching and scratching the surface of stainless steel pipe due to opening the packing bag.

The surface quality, appearance and dimensional accuracy of cold rolled steel strip are better than those of hot rolled plate.

Construction materials shall be prepared and delivered to the site according to the data scheme, and shall be supplied according to the scheme.

2B cold rolling shall be subject to heat treatment, pickling or similar treatment, and then leveled to obtain appropriate gloss.

middleman.(IV) high level operation of steel plant and social inventory. The contradiction between market supply and demand spread to the circulation field, and the domestic steel inventory continued the growth trend at the end of the previous year. On March 15, it reached a historical high of 22.52 million tons, including 14.32 million tons of construction steel inventory, accounting for 66% of the total inventory. After that, with the increase of seasonal consumption, the inventory gradually fell back to 15.4 million tons on July 26. The oversupply in the market also pushed up the inventory of steel mills. In mid March, the steel inventory of key enterprises reached a historical record, reaching 14.51 million tons a year-on-year increase of 27%. In late June, it fell to 12.68 million tons, stainless steel coil, stainless steel belt, stainless steel pipe and other products have a complete variety and sell well at home and abroad. The equipment has a long service life! Products lead the industry in wire products. Welcome to inquire. An increase of 4% over the same period in 2012.

3 after deep drawing, small black spots and RI high imitation dging will also appear on the surface of the area with large deformation which will affect the BQ attribute.

The inner and outer surfaces of precision stainless steel pipe and thick wall pipe shall be free of cracks, folds, crazing, cracks, rolling folds, delamination, scabs and other defects, which need to be completely removed (unless they are specially used for machining) And after removing the stainless steel pipe wall, the wall thickness and outer diameter shall not exceed the negative deviation. As long as some minor surface defects that do not exceed the allowable negative deviation do not need to be removed.

The corrosion resistance of duplex stainless steel, which is widely used in many media, is better than that of ordinary l austenitic stainless steel, while super duplex stainless steel has very high corrosion resistance. In some media, such as acetic acid and formic acid, how should you choose?

Measures to improve the welding quality of stainless steel pipe in order to ensure that the outer surface of stainless steel pipe is not damaged and purified, the maintenance of stainless steel pipe should be strengthened in each process of consumption, mainly including the following three aspects: the processing and consumption of stainless steel pipe should have a special consumption workshop (wood board is well used) , avoid the machining platform of austenitic stainless steel and carbon steel or solid overhead.

HL polishing with appropriate particle size abrasive material to make the surface show continuous grinding lines.

Stainless steel is a very thin, firm, fine and stable chromium rich oxide film (protective film) formed on its surface. It prevents oxygen atoms from penetrating and oxidizing, and obtains corrosion resistance. Once this film is continuously damaged for some reason, oxygen atoms in the air or will continue to separate out, forming loose iron oxide. For a long time,MONEL400 stainless steel plate, stainless steel plate, stainless steel coil and stainless steel belt will be provided Stainless steel pipe, a 20-year-old brand, has advantages in price and guaranteed quality! The metal surface is constantly corroded

　　408— Good heat resistance, weak corrosion resistance, 11% Cr, 8% Ni.
