Product Description:

In thick plate is 4.5 25.0 mm thickness steel plate,

In the thick plate

In the thick plate

Thickness is 25.0 100.0 mm thick plate, thickness more than 100.0 mm thick plate.

In thick plate is mainly used in construction, machinery manufacturing, container manufacturing, shipbuilding, bridge construction, etc. Also can be used to make all kinds of containers, furnace shell, furnace plates, bridge and vehicle static steel plate, low alloy steel plate, shipbuilding steel plate, boiler plate, pressure vessel steel plate, plate, automobile beam steel plate, some parts and welding tractor components, etc. Through the thick plate USES: widely used in the manufacture of containers, furnace shell, furnace plates, bridge and vehicle static steel, low alloy steel plate, steel Bridges with steel plate, made of steel plate, boiler plate, pressure vessel steel plate, plate, automobile beam steel plate, some parts and welding tractor component specific application.


Steel plate for large railway Bridges, requirements under dynamic load, shock, vibration, corrosion, etc., such as: Q

Pressure vessel plates

Pressure vessel plates

235 q, Q345q, etc.


Used in the manufacture of Marine and inland ship hull, require high strength, plasticity, toughness and the cold bending property, welding performance, corrosion resistant performance is good. Such as: A32, D32, A36, D36, etc.

Boiler plate, boiler plate: used in the manufacture of all kinds of boiler and important attachment, because the boiler plate in medium temperature (below 350 ° C) work under the high pressure condition, except under high pressure and impact, fatigue load and water and gas corrosion, and the requirements to ensure certain strength, but also has good welding and the cold bending property, such as: Q245R, etc.

The pressure vessel

Mainly used in the manufacture of petroleum, chemical separation and gas storage and transportation of pressure vessels and other similar devices, general work pressure at atmospheric pressure to 320 kg/cm2 to 630 kg/cm2, even in - 20-450 ° C temperature within the scope of work, for the container plate except a certain strength and good plasticity and toughness, must also have good cold bending and welding performance, such as: Q245R, 15 crmor Q345R, 14 cr1mor, etc.

Car girder

Girders making cars (longitudinal beam, beam), the thickness of 2.5 12.0 mm low alloy hot rolled steel plate. Due to the complexity of automobile beam shape, besides demanding strength and cold bending performance, also requires stamping performance is good.

Q:What does galvanized steel sheet "-PPGI" mean?
Prepainted, galvanised, steel abbreviation for galvanized coated steel (plate / strip).PPGI is the coating of steel (galvanized, zinc plated, nickel plated, etc.) for surface chemical treatment (degreasing, phosphating, chromium, hydrochloric acid passivation), and then coated with paint, and then baked products.
Q:Steel plate coated cement mortar, how can bonding firm?
The simplest method is mortar plus adhesive; the additive used for bonding steel is not cheap.
Q:Definition and application of steel sheet pile
Cold rolled steel sheet pile is a steel structure formed by continuous rolling and forming of a sheet pile wall from a cold bending millNot knowing, then asked
Q:Why can steel HPB300, steel plate without Q300, steel structure manuscript review, but also continued the Q235, why not improve it?
Carbon steel according to the steel yield strength is divided into 5 grades: Q195, Q215, Q235, Q255 and Q275 of each grade because the quality is divided into A, B, C, D grade, with a maximum of four kinds, some only one; this is just plain carbon steel, the price is cheap, generally not heat treatment. Only quality carbon steel has the value of heat treatment.
Q:How can the steel plate of flat welding 10mm make its deformation smaller?
High technical content is: two side groove, one side of the groove is deep, one side of the groove is shallow, the depth of difference is a seam, the two sides welding at the same time, pay attention to the deep groove of this face to be in the lead.Other ways to prevent the in-plane deformation of steel plate are: back welding, skip welding and so on.
Q:What is the electromagnetic steel plate in the generator?
The use of silicon steel sheet generator is designed to: 1) as magnetic pole and magnetic path with smaller excitation current can get larger magnetic field; 2) adding silicon steel material, increases the permeability and resistance to reduce eddy current losses in the steel sheet; 3) the steel sheet made of a film, increase the path of vortex flow, reduce the eddy current loss.
Q:What is the difference between cold rolling and hot rolling?
Hot rolling and cold rolling are forming processes of profiled steel or sheet steel. They have a great influence on the microstructure and properties of steels. Steel is rolled mainly by hot rolling, and cold rolled only for the manufacture of small sections of steel and thin plates. I. advantages of hot rolling: it can destroy the casting structure of steel ingot, refine the grain of steel, and eliminate the defects of microstructure, so that the steel structure is compact and the mechanical properties are improved. This improvement is mainly in the direction of rolling, so that the steel is no longer isotropic to a certain extent;
Q:What is a fixed length steel plate?
Please check the standard: GB/T706-2008 hot-rolled steel fixed length is in accordance with customer requirements made of length, usually 6 meters, 9 meters look
Q:How is the normalized steel plate produced?
Normalizing is the process of heating a steel member to 30-50 degrees above the critical temperature and cooling it in stationary air after proper heat preservation. This process is called normalizing.
Q:STCC what's the quality of the cold rolled steel sheet?
Cold rolled steel: rolled without heating at room temperature (strictly speaking below the recrystallization temperature).
