What are the precautions for Q345D grade high strength structural steel flame cutting

In terms of ship steel, according to industry experts, steel is mainly used in the construction of ship hulls, cargo holds, piping systems (including pumps and valves) and part of ship decoration. In addition to being used to build conventional ships, steel also plays an important role in the construction of various special ships such as LNG (liquefied natural gas) ships, large oil tankers, large container ships, and chemical tankers.

The company adheres to the "variety, quality and efficiency" road. We have established a technology center, a brand cultivation management system and a quality control system. Now the company has formed an independent innovation system integrating Q345D grade high strength structural steel production, learning, research and marketing. Our company has passed ISO9001 quality management system certification and ISO10012 measurement management system certification.

Temperature has a great influence on the strength of the material, Q345D grade high strength structural steel. When the temperature exceeds a certain value, the strength limit of the steel will be reduced. The higher the temperature, the lower the strength. In addition, the longer the steel is used at high temperature, the lower the strength. Therefore, if the steel works at high temperature for a long time, the instantaneous strength of the steel can not be used as its performance index, nor can the room temperature performance replace the high temperature performance.
