What is the general specification of the steel plate? Steel material classification

Everyone knows the steel plate. It is a kind of building material which is more common in the building. There are many places that can be used for steel plates. There are many kinds of steel plates. There are thin plates and thick plates. If you choose our needs, then the steel plate specifications are generally How much? How to classify the material of the steel plate? If you want to know the knowledge of this, then the Xiaobian of the home of the decoration will come to you.

First, what is the general specification of steel plate?


1. The width of the sheet is 500~1500 mm; the width is 600~3000 mm. The thin plates are divided into steel grades, such as ordinary steel, high-quality steel, alloy steel, spring steel, stainless steel, tool steel, heat-resistant steel, bearing steel, silicon steel and industrial pure iron sheet; according to professional use, there are oil drums, Enamel plate, bulletproof plate, etc.; according to the surface coating layer, there are galvanized sheet, tin plate, lead plate, plastic composite plate.


2. Under normal circumstances, the maximum hardenable diameter of carbon steel water quenching is only 10mm-20mm. Strength and yield are relatively low. For example, the σs of ordinary carbon steel Q235 steel is 235 MPa, while the σs of low alloy structural steel 16Mn is 360 MPa or more. The σs /σb of 40 steel is only 0.43, which is much lower than that of alloy steel.

Second, the material classification of steel plates


1. Introduction of hot-dip galvanized steel sheet is produced by hot-dip steel strip or cold-rolled steel strip as a substrate and subjected to continuous hot-dip galvanizing process to prevent corrosion and rust on the surface of thin steel sheets and steel strips. The hot-dip galvanized sheet is supplied by cross-cutting in a rectangular plate; the hot-dip galvanized coil is supplied by winding in a roll form. Due to the different substrates used, hot-dip galvanized steel sheets can be divided into hot-rolled galvanized coils and cold-rolled hot-dip galvanized coils, which are mainly used in construction, home appliances, automobiles, containers, transportation, and home industries. Especially in the steel structure construction, automobile manufacturing, steel plate manufacturing and other industries.


2. Introduction of electro-galvanized steel plate The electro-galvanized steel product is rolled by the cold-rolling mill and then annealed by the CAPL unit. After entering the electro-galvanizing unit, the surface is cleaned. Under the action of the electric field, zinc is continuously deposited from the aqueous solution of zinc salt to the pre-existing The process of obtaining a surface galvanized layer on the surface of the prepared steel strip. Continuous electroplated zinc cold-rolled steel sheets and strips are suitable for use in the automotive, electronics, and home appliances industries. The delivery method is mainly based on the delivery of steel coils, and the required steel plates and strips can also be obtained by cross shearing or slitting.


3. Introduction to ordinary cold rolled sheet is a product obtained by cold pressing of hot rolled sheet. Due to the multi-pass cold rolling, the surface quality is better than that of the hot-rolled sheet, and after the heat treatment, good mechanical properties can be obtained.


Steel plate is common in our life. It is popular among building materials. What is the general specification of steel plate? What kind of material classification is there with steel plate? I think that everyone knows about it through Xiaobian’s introduction. Then if you still want to know more about decoration, please continue to pay attention to the decoration home Internet cafe.

Trichloroisocyanuric acid is shortly name TCCA , its a strong oxidant and chlorinating agent and most important bleaches, chlorinating agent and disinfectants advantage with high effective chlorine content, stable storage and transportation its high bactericidal and bleaching power. Widely use in fungicides for Industrial Water Treatment, swimming pool, hospital etc.
1.Swimming pool: TCCA is good fungicide in swimming pool. Its most wide to be better disinfect.
2.Hospital: the trichloroisocyanuric ACID is also good use in hospital, its high chlorine content, stable storage and convenient molding and use.
3.Using in industrial Water Treatment like textile, rubber etc, or industrial oxidant. The trichloroisocyanuric acid is a chloroisocyanuric acid compound. It is a more important bleaching agent, chlorinating agent and disinfectant.
