%).It means: 100 times of Dr + iron loss value (iron loss value per unit weight when 50Hz repeated magnetization and sinusoidal magnetic induction intensity is 5T) + 100 times of thickness value. For example, dr510-50 indicates that the iron loss value is hot-rolled silicon steel plate with thickness of 0.5mm. The grade of hot rolled silicon steel sheet for household appliances is expressed by JDR + iron loss value + thickness value, such as jdr540-50.

. The agitation in the futures market is more direct. If there is an abnormal change in inventory, whether it increases or decreases, it will become a speculative type of mall participants.

.The numbering rules adopt element symbols; Pinyin, open hearth steel: p; Boiling steel: F; Killed steel: B; Class a steel: a; T8: special GCr15: ball.

From the perspective of metallography, because stainless steel contains chromium a very thin chromium film is formed on the surface, which is separated from the corrosion resistance of oxygen invaded in the steel.

.Summary of plate manufacturing method according to surface characteristics surface characteristics application silver white matte hot rolled to the specified thickness, and then annealed and descaled. A rough and matte surface does not need surface gloss. Silver white cold rolled heat treatment and pickling 2D products are used for applications with lax surface requirements. For general materials, the gloss of deep drawing materials is stronger than that of D treatment, After finishing a light cold rolling with polishing roller, the general material Ba is as bright as a mirror. There is no standard, but it is usually the surface processing of bright annealing, and the surface reflectance is very high. For building materials, 100 ~ 200 # (unit) abrasive belt is used for kitchen coarse grinding to grind building materials, The polishing surface obtained by grinding with 150 ~ 180 # abrasive belt in the middle of the kitchen is the same as that obtained by fine grinding. The polishing surface is polished with 240 # abrasive belt. The ultra-fine grinding in the kitchen is polished with 320 # abrasive belt. The luster is similar to that of Ba. It is generally used for grinding with 400 # polishing wheel. It is used for construction. It is specialized in stainless steel plate, stainless steel coil and stainless steel belt, Stainless steel pipe quality assurance. New and old customers are welcome to consult during the preferential activities. HL hair line grinding in the kitchen is carried out by grinding materials with appropriate particle size for hair line grinding (150 ~ 240#). There are many buildings and building materials close to mirror grinding. 600# rotary polishing wheel is used for grinding for art, mirror grinding for mirror, and polishing wheel is used for grinding reflector, For decoration, according to the purpose, bridge steel plate, boiler steel plate shipbuilding steel plate, armored steel plate, automobile steel plate, roof steel plate, structural steel plate, electrical steel plate (silicon steel sheet), spring steel plate, special solar plate (Hairui special steel) are common Japanese brands in other steel plates for ordinary and mechanical structures.

Stainless steel has the ability of atmospheric oxidation,Stainless steel seamless welded pipe, that is, it does not rust. At the same time, it also has the ability of corrosion resistance in the medium containing acid, alkali and salt, that is, corrosion resistance. However, its corrosion resistance changes with its own chemical composition, mutual state, service conditions and environmental medium type. For example,20 large diameter seamless steel pipe, 304 has absolutely excellent corrosion resistance in dry and clean atmosphere,TP304 stainless steel pipe, but it is moved to In coastal areas in the sea fog with a lot of salt, it will soon rust, while 316 stainless steel performs well. Therefore, not any kind of stainless steel can resist corrosion and rust at any time

The cold rolled steel strip has good strength and yield ratio, and the hot rolled steel strip has good ductility and toughness.

Stainless steel tubes can be found everywhere in our daily use. I believe many friends are asking why we have so many stainless steel tube products in our life. Therefore, and can be used as stainless steel spring and clock spring after deformation strengthening.

  410— Martensite (high strength chromium steel) low-temperature equipment components in refrigeration industry, good wear resistance and poor corrosion resistance.

Honesty and mutual benefit.  SPHC—& mdash; In the first place, s is the abbreviation of steel, P is the abbreviation of plate, h is the abbreviation of hot heat, and C is the abbreviation of commercial. It generally represents hot-rolled steel plate and strip.

  409— Cheap model (British and American), usually used as automobile exhaust pipe, is ferritic stainless steel (chromium steel).

The steel strip can be delivered without heat treatment under the condition that all properties meet the standard requirements. Ordinary drawing grade steel strip is allowed to be delivered without heat treatment.

After hot rolling, it is subject to heat treatment and pickling treatment.

Welcome calls .Stainless welded pipe (grade y) gb3280-84 stainless cold plate (grade I)

Pipeline direct drinking water has developed rapidly. With the development of national economy, pipeline direct drinking water has developed rapidly in domestic cities such as Beijing, Shenzhen, Shanghai and Chongqing, and economically developed medium-sized cities have also actively planned to catch up. In direct drinking water, stainless steel pipe system is undoubtedly second to none. At present, domestic high-grade hotels and public places have been equipped or are equipped with direct drinking water pipes.

  ≥520EL(%)

.Usage: it is widely used in automobile industry, aviation industry and other departments.

  302— The corrosion resistance is the same, and the strength is better because the carbon content is relatively high.

The selection of stainless steel plate shall consider the operating conditions, such as manual operation or automatic operation, the performance and type of hot press, such as hardness, gloss, it is required to produce a number of decorative plates with slow quality.
