Product Description:

B610CFHL4 low sensitive welding cracking steel plates steel for bifurcated pipe

B610CFH series high strength Q&T steels with low sensitive welding cracking for metal components of large-scale hydropower station

The B610CFHL2, B610CFHL4 high strength Q&T steel plates with low sensitive welding cracking are developed by Baosteel and can be used to construct and manufacture of large-scale hydropower station (such as penstock, spiral case and bifurcated pipe in hydropower station). The lowest service temperature of those plates are -20or -40respectively. Currently the available thickness is from 10mm to 100mm. Higher strength steel plates, such as B690CFHL2, B690CFHL4, B780CFHL2 and B780HL2 can be available for the construction of hydropower station.

Mechanical properties of B610CFHL2 & B610CFHL4 steel plates for metal component of hydropower station

Remarks:1. The yield strength value applies to the Rp0.2 , if the yield strength is not pronounced.

        2. The requirement of impact energy can be consulted by supplier and purchaser.

3.The meanings of B610CFHL2 & B610CFHL4:”B” represents “Baosteel”, “610” represents minimum tensile strength(Mpa) and “CF” represents crack free. “H”represents hydropower purpose,”L2” represents the impact test temperature is minus 20, and “L4” represents the impact test temperature is minus40.

4. In order to distinguish the steel plates for spherical tank and hydropower, the grades of B610CF and B610CF-L1 originally used for hydropower purpose are revised into B610CFHL2 & B610CFHL4.
