CN101215669A - High-strength thick steel plate for large

The invention relates to a method for preparing a high strength thick steel plate for a large oil storage tank in a low cost,the method particularly applies to a high strength thick steel plate for a large oil storage tank,which is welded by line energy which is equal or less than 120 KJ/cm.The weight percentages of chemical constituents are that carbon is 0.01-0.12 percent,silicon is 0.15 Carbon and Low-alloy High-strength Steel PlateUT (Ultrasonic examination),AR(As Hot Rolled only),TMCP(Thermal Mechanical Control Processing),N(Normalized),Q+T(Quenched and Tempered),Z Direction Test(Z15,Z25,Z35) ,Charpy V-Notch Impact Test,HIC test,NDT,PWHT( Simulated Post Weld Heat Treatment) NACE0175 The Third Party Test (Such as SGS Test),Coated or Shot Blasting and Painting.

Carbon and low alloy steel plate - BBN Steel

Carbon and low alloy steel also known as Mild steel.steels with a low carbon content and without alloy are softer and more easily formed,it is a low-cost material that is easy to shape.While not as hard as higher-carbon steels,carburizing can increase its surface hardness.carbon structural steel has the proper tensile strength,good toughness,plasticity,processing property.LR,ABS,NK,GL,DNV,BV,KR,RINA,CCS AH40 Shipbuilding LR,ABS,NK,GL,DNV,BV,KR,RINA,CCS AH40 Shipbuilding steel plate Capable Classification Society Quality Authentication from LR,ABS,NK,GL,DNV,BV,KR,RINA,CCS,AH40 steel plate is mainly used for shipbuilding and oil platform,the shipbuilding grade AH40 can be used in the manuf

Low temperature impact toughness of high strength

q800d quenched tempered steel plate gb t 16270 q800d#0183;Table 7 shows that,at the same temperature,not only A kv but also D kv,T decreases with the increasing nominal yield strength.For steels with the same nominal yield strength,D kv,T decreases with increasing plate thickness.The D kv,T of Q690-20-BM are 2.6~4.9% lower than those of Q690-10-BM,indicating a slightly better impact performance Microstructure and mechanical properties of 780 MPa high The microstructure and mechanical properties of reheat quenched and tempered (RQT) steel plate were compared with those of direct quenched and tempered (DQT) steel plates which were hot rolled
