Gao Jiangang Q345GJB
The full name of Gaojian Steel is high-performance steel for building structures. It is mainly used in high-rise, super-high-rise buildings or large-scale steel structures, sports and exhibition venues and other projects. Due to its excellent weldability, low temperature resistance, and shock resistance. Due to the low alloy sheet in tensile strength, both carbon equivalent and yield strength are required.

Application of wear plate
1) Thermal power plant: medium-speed coal mill barrel lining, fan impeller socket, dust collector inlet flue, ash duct, bucket turbine lining, separator connecting pipe, coal crusher lining, coal hopper and crushing Machine liner, burner burner, coal drop hopper and funnel liner, air preheater support tile, separator guide vane. The above-mentioned parts do not have too high requirements on the hardness and wear resistance of wear-resistant steel plates, and can use wear-resistant steel plates made of NM360/400 with a thickness of 6-10mm.

What is weathering board? Detailed introduction of weathering board
What is weathering board? Many people do not know what weathering board is. Weathering board is also a kind of material commonly used in decoration. It can be used outdoors for a long time, and it is not found that aging, rusting and degeneration are the general term for a material. So let's take a look at what is weathering board.

How much do you know about boiler plates?
It is used to manufacture various boilers and important accessories. Since the boiler steel plate works under high pressure at medium temperature (below 350°C), in addition to high pressure, it is also subjected to impact, fatigue load and water and gas corrosion. It is required to ensure a certain strength. Must have good welding and cold bending properties. Such as: 20g, 16Mng, etc.
