BBN STEEL supply various size of plate product steel grade S690Q
Size stock: 16*1555*11400, 12.7*3316*10500, 12.7*2438.4*12192, 23*2330*11300, 12.7*2518*11380, 6.5*2450*12500, 18*1860*12000, 12.7*2515*12000, 9*2440*12500, 15.1*1550*10400, 12*2680*12000, 12*2520*12000, 18*2020*12000, 11*2365*12000, 14*3470*12000, 12.7*2518*11380, 18*1700*12000, 9.2*2530*12000, 12*2680*12000, 68*2350*7500.

The weight of seamless steel pipe is only 1 / 5 of that of square steel. Seamless steel pipe corrosion resistance acid, alkali, salt and atmospheric environment corrosion, high temperature resistance, good impact and fatigue resistance, do not need regular maintenance. The effective service life of product steel grade S690Q more than 15 years.

The main problem of safety education in iron and steel enterprises is not that the company does not pay attention to it and does not implement it, but that the subordinate units do not strictly follow the company's requirements. In order to avoid the problem of safety education becoming a mere formality, BBN steel company improved the safety education model from the following aspects: First, the content of safety education should not only pay attention to the accumulation of safety knowledge, but also pay attention to the mastery of safety operation skills.

The basic phases of steel grade S690Q, structural steel in the annealed state are ferrite and carbide. The alloy elements are dissolved in ferrite to form alloy ferrite, which depends on solid solution strengthening to increase strength and hardness, but at the same time reduce plasticity and toughness. The addition of alloying elements reduces the carbon content of the eutectoid point, which increases the proportion of pearlite in the structure and reduces the distance of the pearlite layer. This also increases the strength of the steel and reduces the plasticity.
