Hot rolled A387 GR.11 CL.1 pressure vessel steel sheet product stock size: 12*1600*91000, 25*1950*10250, 25*1950*10150, 14*2000*10000, 12*1600*10000, 16*1500*9340, 60*2020*6100, 25*1950*9700, 14*2000*13500, 75*2390*4320, 16*1500*9340, 50*2740*13460, 20*2100*10700, 20*2500*6200, 60*1750*9100, 34*1900*12000, 12*2050*5100, 45*2010*10000, 25*2100*8650, 70*2270*7600, 16*1500*9340, 6*1950*10000, 30*2000*7630, 20*2100*11600, 70*2260*7950, 34*1900*12000.
Penetration testing technology is only suitable for detecting surface defects. It uses penetrant to apply on the surface of the A387 GR.11 CL.1 pressure vessel steel sheet steel plate, then wipes the excess penetrant with the cleaning solution, and then smears the developer. The penetrant remaining in the defect is adsorbed by the developing material, so as to observe the shape of the defect and determine the type of defect. This A387 GR.11 CL.1 pressure vessel steel sheet method requires multiple wipes before and after the inspection, the process is more cumbersome, and can not detect internal defects and rough and dirty steel plates.
Phosphorus is a very harmful element in A387 GR.11 CL.1 pressure vessel steel sheet steel. With the increase of phosphorus content, the strength, flexion ratio and hardness of A387 GR.11 CL.1 pressure vessel steel sheet steel increased, but the plasticity and toughness decreased significantly. In particular, the lower the temperature, the greater the impact on plasticity and toughness, increase the cold brittleness of steel.
The formula of enterprise success is: success = strategy × organizational capability, that is, having the right direction and strong organizational capability. The core competence of an enterprise depends on three pillars: first, talents (talent echelon); second, core values of enterprise culture; third, organizational governance model. If the enterprise is a tree, then the core values of talents, corporate culture and organizational governance mode are just like the root of the tree. With them, the enterprise will flourish and grow forever.
