Supply the BBN S690QL high strength steel plate technical specification

In April 2018, our Philiphine customer purchased 1008 Tons API5 L Gr.B ERW&Q345B SMLS pipe S690QL high strength steel plate for offshore oildfield resources drilling project. This is a regular demand almost two month, and we has been cooperated more than three times, totally around 2100 tons steel pipe since 2015 year.

S690QL high strength steel plate 5mm to 10mm stock size5.5*2900*7400, 8*2400*6000, 9*2500*9500, 5*3000*5200, 6*2350*6300, 10*2000*6500, 8*2400*8000, 7*3000*6600, 6*2350*7400, 10*2150*5500, 8*2300*9000, 8*2400*8000, 6*2350*7200, 10*2550*10500, 8*2490*7200, 8*1800*10000, 10*2360*7700, 10*2490*8400, 9*2500*7400, 8*1800*8000, 10*2450*8000, 10*2100*11000, 10*2450*8000, 10*1650*9020.

S690QL high strength steel plate annealing is to heat the steel to 30 ~ 50℃ above the critical temperature, keep it in the heat treatment furnace for a period of time, and then cool it down to room temperature with the furnace. The purpose of S690QL high strength steel plate annealing is to refine the grain of steel, eliminate internal stress and reduce hardness, improve cutting performance, increase toughness and plasticity, and facilitate welding and rolling processes. S690QL high strength steel plate annealing can be complete annealing, incomplete annealing, stress relief annealing, isothermal annealing and spheroidizing annealing.

In mid-October, news from Shanxi called for the elimination of more than 20 million tons of coke oven capacity below 4.3 meters before the end of the year. By the end of October, 12.3 million tons of production capacity had been eliminated, and in November, 10.52 million tons were expected to be eliminated. In the later period, localities will successively announce plans for reducing production capacity during the heating season this year, involving 29.73 million tons of coking capacity.
