q345r equivalent material HIC plate

The typical hardness of NM500 steel plate is 500 HBW, so it can withstand severe wear. NM500 steel plate is very suitable for working in strong wear environment, such as high strength ore and corrosive materials. NM550 steel plate is a kind of wear-resistant steel plate with an average hardness of 550 HBW. q345r equivalent material Its toughness is the same as that of NM500 steel plate, and it is used in high wear occasions. When the NM500 steel plate is upgraded to NM550 steel plate, the Brinell hardness is increased by 50 units, and the wear resistance life is prolonged without losing the toughness of the q345r equivalent material steel plate.

Boiler steel mainly refers to materials used to make superheaters, main steam pipes and heating surfaces of boiler fire chambers. Boiler steel is a totally different material from q345r equivalent material. The performance requirements for boiler steel are mainly good welding performance, certain high temperature strength, alkali corrosion resistance, and oxidation resistance. Commonly used boiler steels include open-hearth smelted low-carbon killed steel or electric furnace smelted low-carbon steel, with carbon content Wc in the range of 0.16%-0.26%. When manufacturing high-pressure boilers, pearlitic heat-resistant steel or austenitic heat-resistant steel is used. In recent years, ordinary low-alloy steel has also been used to build boilers.

Most common q345r equivalent material steel plates are rolled by hot rolling or controlled rolling. Compared with the general hot rolling process, the advantages of controlled rolling are: the strength and low temperature toughness of steel plates are greatly improved by controlled rolling to refine grains. In addition, the controlled rolling process can give full play to the role of Microalloying Elements Nb, V and Ti, not only play a role of precipitation strengthening, but also refine the grains, and improve the toughness of the rolled q345r equivalent material steel plates.

The company has a high-quality management, technology and R&D team, and adopts independent research and development, domestic innovative process optimization combination. Relying on advanced manufacturing technology and sophisticated production testing equipment, it has ensured the high quality of products q345r equivalent material and won a good reputation. We can offer various kinds of steel materials in GB, ASME, ASTM, JIS, DIN, EN, API standards and specifications.

The company attaches great importance to the cultivation of team spirit. Personal strength is weak. After sales service departments, leaders and subordinates often communicate with each other. Everyone often holds meetings to discuss their problems in after-sales service, discuss technical difficulties, discuss how to improve work efficiency, how to better deal with user complaints, etc.
