Q245R (R-HIC is a steel plate for pressure vessels). It is also known as R-Hic steel plate, where R stands for"Steel plates for pressure vessels", HIC said"Hydrogen-induced cracking susceptibility"。The main characteristics of this steel plate are good weldability, high heat resistance and pressure resistance.
Q245R (R-HIC) steel plate is commonly used in the manufacture of pressure vesselsWugang Xinze Steel, boilers and other similar equipmentLi Tang, its main use is to store or process high pressure in various industrial fieldsGases or liquids at high temperatures. Q245R (R-HIC) steel plate in petrochemical,It has a wide range of applications in the chemical industry, power stations and other fields
The chemical composition of this steel plate usually includes elements such as carbon (C), silicon (Si), manganese (MN), sulfur (S), phosphorus (P), etc. These chemistries ensure that the steel plate has good weldability and mechanical properties.
One of the characteristics of Q245R (R-HIC) steel plate is its high heat resistance. It is able to work for a long time at higher temperatures without deformation or damage, which is due to the addition of suitable alloying elements to the steel plate to improve its high temperature resistance. At the same time, the steel plate has excellent pressure resistance and can withstand high internal pressure without deformation or cracking.
Another important feature is that Q245R(R-HIC) steel plate has good weldability. This is critical for the manufacture of pressure vessels, which often require multiple welding processes to assemble. The weldability of steel plates means that various welding methods can be used to join steel plates together, such as arc welding, gas shielded welding, etc.
In addition, Q245R (R-HIC) steel plate also has certain corrosion resistance, which can resist corrosion in the environment and the erosion of chemical media to a certain extent.
In general, Q245R (R-HIC) steel plate is a kind of high-strength, low-alloy pressure vessel steel plate with excellent mechanical properties, good weldability, heat resistance and certain corrosion resistance. It is widely used in various industrial fields to meet the manufacturing needs of pressure vessels and ensure the safety of equipment under high pressure and high temperature.
