shipbuilding use GL-D hull structural steel for engineering project

With equipment, technology, production technology, quality supervision and other leading advantages, we are leading in the production of all kinds of high-quality, high-tech medium, extra thick, extra wide steel plate shipbuilding use GL-D hull structural steel shaped parts. The cutting surface is smooth and clean, the cutting edge is neat, without secondary processing by users, and it can be installed and used directly according to the technical dimensions, with the characteristics of high coincidence rate of positive and negative tolerance and excellent quality. The processed steel products are mainly used in heavy machinery and equipment.

Ultrasonic flaw detection emits ultrasonic waves to the shipbuilding use GL-D hull structural steel steel plate under inspection. If there are defects in the steel plate, the ultrasonic waves will reflect, refract or deform waveforms due to the defects. By recording these changes, the type and shape of the defects are analyzed. Due to its high energy and good penetration performance, and the smoothness of the shipbuilding use GL-D hull structural steel steel plate itself, ultrasound is often used to detect defects such as inclusions, shrinkage holes, bubbles, and cracks in the steel plate.

Phosphorus element (P element) is brought into steel by ore. Generally speaking, phosphorus is also harmful element. Although phosphorus can increase the strength and hardness of shipbuilding use GL-D hull structural steel etc. steel, it also causes the decrease of plasticity and impact toughness. Especially at low temperature, it makes steel significantly brittle, which is called "cold brittleness". The higher the phosphorus content is, the greater the cold brittleness is. Therefore, the phosphorus content in shipbuilding use GL-D hull structural steel etc. steel is strictly controlled.

Tata Steel Europe plans to cut 1250 jobs. Henrik Adam, CEO of Tata Steel, said: "the financial situation of Tata Steel Europe is very serious at present, and there is an urgent need to improve the company's performance and financial situation." Tata Steel has decided shipbuilding use GL-D hull structural steel in November 2019 to cut 3000 jobs in its European operations to reduce costs. After a period of negotiations with the European labour Commission, the layoff plan cut that number by more than half, minimizing unemployment. Tata Steel has about 20000 employees in Europe.
