Composition design of hardox 450 steel hardness

The company adheres to the principle of integrity, standardization and efficiency, wins the market with technology, gains reputation with creative services, and wholeheartedly provides customers with high-quality Hardox 450 steel hardness, efficient and fast services. Facing the future, adhere to independent innovation.

The commonly Hardox 450 steel hardness steels used to manufacture pressure parts of boilers mainly include low carbon steel, low alloy structural steel, low alloy heat-resistant steel, austenitic stainless heat-resistant steel and martensitic heat-resistant steel, etc. According to profiles, these boiler steels can be divided into boiler steel plates and boiler steel pipes. Our main Hardox 450 steel hardness boiler steel materials are as follows: A516 Gr 70, A537 class 1 , 16Mo3, Q345R, A204 grade B, A285C, ASTM A387, P355GH and so on.

What is the difference between Q345B steel and Q345A steel? Hardox 450 steel hardness, Q345B steel and Q345A steel have slight difference in chemical composition: Q345A steel: C ≤ 0.20, Mn ≤ 1.7, Si ≤ 0.55, P ≤ 0.045, S ≤ 0.045, V 0.02 ~ 0.15; Q345B steel: C ≤ 0.20, Mn ≤ 1.7, Si ≤ 0.55, P ≤ 0.040, S ≤ 0.040, V 0.02 ~ 0.15. The difference between Q345B steel and Q345A steel is mainly in A and B behind the steel grade, Q345A steel grade is not subject to impact; Q345B steel grade needs 20 ℃ room temperature impact test.

Compared with ordinary carbon steel plate, manganese steel plate has the following advantages. First, Hardox 450 steel hardness, manganese steel plate is convenient for welding and processing. Second, manganese steel plate has good heat resistance, and can be processed into various containers. Third, manganese steel plate has good toughness. It is not easy to fracture and has long service life. Fourth, the performance of manganese steel plate is good at low temperature. It will not fracture because of temperature, so it can be used in cold areas.

The company attaches great importance to the cultivation of team spirit. Personal strength is weak. After sales service departments, leaders and subordinates often communicate with each other. Everyone often holds meetings to discuss their problems in after-sales service, discuss technical difficulties, discuss how to improve work efficiency, how to better deal with user complaints, etc.
