Usage: widely used in automobile, tractor and other industries.

Stainless hot plate (grade I) GB4239-91 stainless cold strip (grade I)

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

The existence of medium temperature brittle zone requires strict heat treatment and welding process system to avoid the appearance of harmful phase and damage the performance.

.Cold formed alloys can be cut and cold formed. However, due to its high strength and hardness, the alloy needs cold forming more than austenitic steel. Because of its high strength, springback should be fully considered.

The steel grades for JIS mechanical structures are: S + carbon content + letter code (CK), in which the carbon content is represented by the intermediate value & times; 100, the letter C: represents carbon, and K: represents steel for carburizing. For example, the carbon content of carbon coil s20c is 0.18-0.23%. The grades of silicon steel sheets in China and Japan are.

  SPCCSPCC—& mdash; Cold rolled carbon steel sheet and strip are generally used, which is equivalent to q195a. The third letter C is the abbreviation of cold. When it is necessary to ensure the tensile test, add t at the end of the brand as spcct.

Stainless steel tube toxic chromium and nickel is not bad for you? Stainless steel contains a lot of chromium and nickel. Why is stainless steel still? The following Tianjin stainless steel pipe factory will answer for you: food grade stainless steel pipes will be corroded into spots for a long time if they are not soaked in acid (vinegar) and salt for a long time. Good stainless steel is a model and never rusts.

Human factors are also one of the causes of product oxidation that some consumers often encounter when using stainless steel products. Some consumers operate improperly in product use and maintenance, especially some stainless steel pipe products used in food and chemical equipment industry. For the artificially generated oxidation of steel products, they should have correct product use knowledge and Reasonable and effective maintenance shall be carried out regularly to reduce oxidation caused by improper use.

In the past few years, the United States has imposed anti-dumping and countervailing duties on a variety of steel pipe products exported from China, including ring welded pipe, rectangular pipe, pipeline pipe, welded stainless steel pressure pipe oil well pipe and seamless steel pipe. These foreign double back pressures have greatly reduced the number of steel pipes exported by China.

Statistics.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, 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 decoration, mirror grinding for mirror, and polishing wheel is used for grinding reflector, For decoration, bridge steel plate, boiler steel plate, shipbuilding steel plate, armored steel plate automobile steel plate,201 stainless steel square tube, 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.

1: stainless steel plate: it can be divided into cold-rolled plate and hot-rolled plate. Its surface has bright surface,SUS304 stainless steel pipe, fog surface and matte surface. It is commonly known as stainless steel plate, including 2B plate and Ba plate. In addition, it can also be plated with other light colors according to customer requirements. The main specifications of plates are: 1m * 1m,304 stainless steel pipe standard, 1m * 2m, 22m * 44m, 5m * 3M, 5m * 6m. If customer demand is large, we can cut them according to customer size. In addition, we can replace wire drawing plate, anti sliding plate and electroplating plate

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.

If the thickness of the steel plate is not enough, the professional stainless steel plate, stainless steel coil, stainless steel belt and stainless steel pipe are strictly tested and the quality is guaranteed. The preferential activities are in progress. Welcome to consult. It is easy to bend, which will affect the production of decorative plate. If the thickness is too large and the steel plate is too heavy, it will not only increase the cost of the steel plate, but also bring unnecessary difficulties to the operation. At the same time, the allowance that should be left during processing or use of stainless steel plate shall also be considered. The thickness of copper plate is not absolutely consistent, but the thickness of the same steel plate shall be as consistent as possible. Generally, for medium-sized saw plate, the thickness tolerance is 0.05-0.15mm. If the requirements are too strict, the grinding cost will also increase. Generally, it is a structural steel plate with high resistance and high degree. The greater the mechanical damage resistance, the longer the service durability, but the grinding and processing cost is also relatively high.

Good quality.According to different metallographic structure of stainless steel it is divided into semi Ferritic and semi martensitic stainless steel pipe, martensitic stainless steel pipe, austenitic ferritic stainless steel pipe, etc.

Deformation strengthening of austenitic stainless steel stainless steel has good cold deformation performance. It can be cold drawn into very thin steel wire and cold rolled into very thin steel strip or steel pipe. After a large amount of deformation, especially when rolling in the subzero temperature zone. The tensile strength can reach more than 2000 MPa. This is because in addition to the cold hardening effect, there are also superimposed Deformation induced M transition.

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

.Stainless steel belt, stainless steel conveyor belt, stainless steel belt, stainless steel coil belt, ultra-thin stainless steel belt.

Stainless steel is more than twice as high and has enough plastic toughness for forming. The wall thickness of storage tank or pressure vessel made of duplex stainless steel is 30-50% less than that of common austenite, chemical fertilizer and chemical fiber, such as containers, pipelines and structural parts.
