WSD690D steel plate is a kind of hydropower steel with high strength, high toughness, fatigue resistance and laminarity tear resistance, which is mainly used in the manufacture of water inlet pressure pipes, volutes, ribs, turnout pipes and auxiliary equipment in the dam of hydropower station.

The yield strength of WSD690D steel plate is 690, the quality grade is D, and its material has high cleanliness, low content of harmful elements such as P, S, O, N, H and so on, and excellent internal quality.

WSD690D steel plate can be normalized, tempered, quenched and other treatment, thickness can be z15, z25, z35, different delivery forms will present different performance indicators and uses, so in the selection of technical requirements should be based on the current use of the situation to do specific delivery planning.

WH80 steel plate is a kind of high-strength welded steel structural steel plate, often referred to as high-strength plate.

The "W" of the WH80 steel plate represents Wugang, the "H" indicates the kg class high-strength welded structural steel plate, and the "80" indicates the kg class value.

WH80 steel plate is mainly used in the manufacture of steel structural parts with high welding performance requirements, such as construction machinery, mining machinery, coal mining machinery, environmental protection machinery, metallurgical machinery, such as hydraulic support, crane extender arm, crane extender arm, excavator support arm, etc.

WH80 steel plate has good strength and toughness matching, excellent low temperature impact toughness and cold formability, good welding performance, no preheating before welding, no heat treatment after welding.

WDB690(C, D, E) steel plate is a kind of low welding crack sensitivity high strength steel plate, mainly used in hydropower station pressure steel pipe, unit volute and other steel structure with high welding performance requirements.

WDB690(C, D, E) steel plate has the following advantages:

It has good strength and toughness matching.
It has good low temperature impact toughness.
It has excellent cold formability.
It has good welding performance, no preheating before welding, no heat treatment after welding.

The WDB690(C, D, E) steel plate has been successfully developed since 2001, and has met the technical requirements for the use of pressure steel pipes and volutes in dozens of large and medium-sized hydropower stations in China, simplifying the production process of steel pipes and saving production costs.

SX800 steel plate is a kind of high strength, high toughness, fatigue resistant steel plate, mainly used in the manufacture of large machinery, ships, Bridges, oil pipelines, chemical containers, power plant equipment and so on.

This steel plate is made of high quality carbon structural steel and low alloy high strength structural steel as raw materials, after special rolling and heat treatment process, with high strength, high toughness, fatigue resistance and other characteristics.

The advantage of SX800 steel plate is that it has excellent mechanical properties, can withstand greater pressure and impact, and is not easy to deformation and fracture. In addition, it also has good corrosion resistance and heat resistance, and can be used for a long time in a variety of complex environments.

During the manufacturing process, SX800 steel plates need to be strictly tested and controlled to ensure that their quality and performance meet the requirements.

Q500CF(C, D, E) is a high strength steel plate with low welding crack sensitivity, which is mainly used to make pressure steel pipes for hydropower stations, construction machinery, railway vehicles, Bridges, high-rise and long-span buildings with high weldability requirements.

The name of Q500CF(C, D, E) steel plate consists of four parts: the Chinese Pinyin letter Q representing the yield strength "Qu" character, the regular yield strength value, the English letter (CF) representing the international low welding crack sensitivity, and the quality grade (C, D, E).
