Difference between Q345R boiler vessel plate and ordinary Q345 plate, EN 10083-3 33MnCrB5-2 steel:Q345R boiler vessel plate is pressure vessel steel, Q345 plate is low alloy steel.Q345R boiler vessel plate generally requires flaw detection and positive deviation, while Q345 plate generally has lower requirements.In terms of performance, Q345R boiler vessel plate and Q345 plate are of the same level. However, due to high requirements, they can not be mixed in general.Generally, the requirement of Q345R boiler vessel plate is higher than Q345 plate, EN 10083-3 33MnCrB5-2 steel.
In view of the characteristics of container transportation, such as high added value, low cargo damage and short time, our company takes more consideration of port collection and distribution conditions, port facilities, flight density and route coverage when choosing ports. For the convenience of customers, as well as the safety of goods.
Normalizing is to heat the steel parts to 30~80℃above the critical temperature for a period of time. Then the parts are taken out of the furnace and cooled in air. Since the cooling rate of normalizing is faster than that of annealing, the strength and hardness of normalized EN 10083-3 33MnCrB5-2 steel are higher than that of annealed EN 10083-3 33MnCrB5-2 steel, but the elimination of internal stress is not as good as annealing. The normalizing operation of EN 10083-3 33MnCrB5-2 steel is simple, the cost is low, the productivity is high, and it is widely used in actual production.
