  • Wear plate: 

Several well-known international manufacturers of wear-resistant plates include hardox wear- resistant plates from Sweden (SSAB), DILLIDUR from Germany, RAEX from Finland, XAR from Germany , and JFE(EH) from Japan. Among them, the hardox600 wear-resistant steel plate from Sweden is  widely recognized as the wear-resistant steel plate with the highest hardness and strongest wear resistance.

  • Die steel: 

Die steel is a type of steel used to manufacture cold stamping dies, hot forging dies, die-   casting dies and other molds. Molds are the main processing tools for manufacturing parts in industrial sectors such as mechanical manufacturing, radio instruments, motors, and electrical    appliances. The quality of molds directly affects the quality of pressure processing technology,  the precision and output of products, as well as production costs. The quality and service life of molds, apart from relying on reasonable structural design and processing accuracy, are mainly influenced by mold materials and heat treatment.

  • High-strength structural steel plates for Marine engineering:  

Due to the harsh working environment of ships, the hull shells are subject to chemical corrosion and electrochemical corrosion by seawater, as well as corrosion by Marine organisms and  microorganisms. The hull is subjected to considerable wind and wave impacts and alternating loads. The shape of ships makes their processing methods complex and other factors, so strict requirements are imposed on the steel used for the hull structure. First of all, good toughness is the most crucial requirement. In addition, it is necessary to have high strength, good corrosion resistance, welding performance, processing and forming performance, as well as surface quality.

Characterlstics:

 

It features high strength, light self- weight, good overall rigidity and strong  resistance to deformation. Therefore, it  is particularly suitable for the construction of large-span and super-high and super-heavy buildings. The material has good homogeneity and isotropy, and is an ideal elastomer, which best conforms to the basic assumptions of general engineering mechanics. The material has good plasticity and toughness, can undergo significant deformation, and can well withstand dynamic loads. The construction period is short. It has a high degree of industrialization and can carry out specialized production with a high degree of mechanization.

Steel structure components are convenient to be manufactured in factories and assembled on construction sites. The finished products of steel structure components manufactured mechanically in factories feature high precision, high  production efficiency, fast assembly speed on construction sites and short construction periods. Steel structure is  the most industrialized type of structure.
