ISO 9001:2000 Certificated S690QL steel hardness

ASTM A588 steel beam S690QL steel hardness not only has high tensile and yield strength, but also has good atmospheric corrosion resistance due to its small copper content. Due to its high strength, its S690QL steel hardness weight is less than that of A36 steel section without reducing strength. At the same time, it is the best material for outdoor application, the surface is orange.

Plate 20 to 30mm thick S690QL steel hardness product: 20*1400*11400, 20*2100*7000, 20*2500*6200, 20*2933*7300, 20*3200*4400, 20.9*2851*7000, 21*2100*8810, 21.5*1630*13480, 22*3400*13000, 23.1*2590*7790, 25*1950*10150, 25*1950*9700, 25*2100*8400, 25*2100*8650, 25*2400*11600, 25*2400*8200, 28*2170*13000, 30*1600*10720, 30*1600*8600.

The carbon content of S690QL steel hardness, hot rolled steel plate is slightly higher than that of cold rolled steel plate. Hot rolled steel plate has low hardness, easy processing and good ductility. Cold rolled steel plate has high hardness and is difficult to process, but it is not easy to deform and has high strength. The strength of hot-rolled steel plate is relatively low, the surface quality (oxidation finish) is low, but the plasticity is good, and it is generally medium thick plate.

The technical characteristics of activated coke dry desulfurization and denitrification are as follows: (1) In view of the complex flue gas working conditions with sulfur, nitrogen, oxygen, high water content and large fluctuations produced by sintering, as well as working conditions with high requirements for removal efficiency and index stability, advanced two-stage activated coke drying Method purification technology; (2) In order to meet the ultra-low emission requirements of particulate matter, proprietary porous plate and microporous plate technology are adopted; (3) Activated coke feeding and unloading adopts advanced rotary sealing valve technology to reduce the powdering rate of activated coke and improve the sealing effect.
