Q370R steel and 15CrMoR plates have low sulfur and phosphorus content, and have good comprehensive mechanical properties, welding performance and low temperature impact toughness. Q370R low alloy steel is suitable for manufacturing medium temperature and low pressure pressure vessels and their accessories. GL-D40 ore carrier steel plate, 15CrMoR material has low sulfur and phosphorus content, and has good welding performance and impact toughness.
As the boiler steel plate GL-D40 ore carrier steel plate is working under medium temperature (below 350 ℃) and high pressure, the boiler steel plate is not only subjected to high pressure, but also subjected to impact, fatigue load and water and gas corrosion. The performance requirements for boiler steel mainly include good welding and cold bending performance, certain high temperature strength, alkali corrosion resistance, oxidation resistance, etc.
Penetration testing technology is only suitable for detecting surface defects. It uses penetrant to apply on the surface of the GL-D40 ore carrier steel plate 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 GL-D40 ore carrier steel plate 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.
The company is mainly engaged in GL-D40 ore carrier steel plate steel plates manufacturing and deep processing, sales and distribution. It is committed to building a complete modern steel purchase and sale network. Here we would like to express our sincere gratitude to our old and new friends who have always given care, support, affirmation and help, and sincerely hope to establish a long-term cooperative relationship with them for mutual benefit, win-win and common development, and work GL-D40 ore carrier steel plate together for a better tomorrow.
After sales service support personnel pay attention to commitment in their work. In the process of people to people communication, mutual trust is an important factor for the long-term and stable communication. After sales service personnel must do what they say in the process of communication with customers.
