In recent years, in line with the development trend of iron and shipbuilding use GL-D32 weldable steel steel industry at home and abroad, we have accelerated the transformation of development mode, promoted structural adjustment, and formed a rich product series of medium and thick plates, hot rolled steel coils, profiles, steel pipes, etc., which shipbuilding use GL-D32 weldable steel are widely used in automobiles, long-span bridges, railways, machinery, ocean and so on fields. Meanwhile, we also provide deep processing for the steel materials.
As steel transportation belongs to the transportation of major parts, so in the process of transportation, modern logistics technology, such as centralized transportation, information technology, is a bit out of place. Based on the current situation of China's shipbuilding use GL-D32 weldable steel steel transportation industry, highway transportation is a way of transportation that many enterprises often choose. Naturally, its business volume also accounts for more than 50% of the whole shipbuilding use GL-D32 weldable steel steel transportation industry.
"Mirror" refers to the surface state of shipbuilding use GL-D32 weldable steel stainless steel, which is usually 8K in the industry. The common mirror stainless steel on the market is divided into 6K, 8K and 10K, which are general polishing, 6K, 8K fine grinding and 10K super fine grinding effect. The same thickness generally has no big difference, 10K mirror is brighter; the thicker the thickness, the better the effect, and the higher the processing cost.
The Indian customer purchased our A516 Gr 70 pressure vessel steel plates to make tanks. They have very strict requirement for raw materials quality. For the A516 Gr 70 pressure vessel steel plates, they asked for Normalizing, 0℃ impact, A578 UT test, PWHT and so on tests, our Q/C department witness the production process with the technician from the customer company together. Meanwhile, we arrange BV inspection to check the quantity, spray mark, stamp on the A516 Gr 70 pressure vessel steel plates, and so on.
Chemical composition differences between the shipbuilding use GL-D32 weldable steel, Q345 steel grades (Q345A / Q345B / Q345C / Q345D / Q345E):Q345A steel：C≤0.20，Mn ≤1.70，Si≤0.50，P≤0.035，S≤0.035； Q345B steel：C≤0.20，Mn ≤1.70，Si≤0.50，P≤0.035，S≤0.035； Q345C steel：C≤0.20，Mn ≤1.70，Si≤0.50，P≤0.030，S≤0.030，Al≥0.015； Q345D steel：C≤0.18，Mn ≤1.70，Si≤0.50，P≤0.030，S≤0.025，Al≥0.015； Q345E steel：C≤0.18，Mn ≤1.70，Si≤0.50，P≤0.025，S≤0.020，Al≥0.015； All the Q345 steel grades contain Nb≤0.07，V≤0.15，Ti≤0.20，Cr≤0.30，Ni≤0.012，Mo≤0.10。
The company uses online training system to let all employees use fragmented time to carry out targeted training anytime, anywhere, regardless of time and geographical restrictions. Through training to improve shipbuilding use GL-D32 weldable steel work skills, at the same time, through training, let all improve their own quality education level, let employees work around a goal, create a career and achieve results.
