hardox 450 vs ar500 for pressure vessels
45# steel is a common medium carbon quenched and tempered structural steel. The cold plasticity of 45# steel is general. Annealing and normalizing are slightly better than Hardox 450 vs ar500 quenching and tempering. 45# steel has higher strength and better machinability. After proper heat treatment, 45# steel can obtain certain toughness, plasticity and wear resistance. 45# steel is suitable for hydrogen welding and argon arc welding, not suitable for gas welding.
Weathering steel plate for welding structure is made by adding metal materials such as chromium, molybdenum, titanium and vanadium to ordinary molten steel. The addition of these materials can form a protective film on the steel surface, which can resist weathering corrosion for a long time. The advantages of weathering steel plate for welding structure: It has very good welding performance and weather resistance, and is widely used in railways, bridges and other areas that need to be exposed to the atmosphere for a long time. Disadvantages of weathering steel plate for welded structure: It has very high requirements on the production process, and the poorer technology can not produce good weathering steel plate, Hardox 450 vs ar500.
Welding is mainly used for manufacturing metal structure parts, and also for manufacturing machine parts. The welding connection performance is good, and it is convenient to weld Hardox 450 vs ar500 steel plates, profiles or castings and forgings according to the needs. At the same time, welding can also connect different shapes and sizes (plate thickness, pipe diameter) or even different materials, so as to reduce weight, save materials, optimize resources and other purposes. The welding structure has high rigidity, good integrity, and easy to ensure air tightness and water tightness, so it is especially suitable for Hardox 450 vs ar500 manufacturing hollow structures with high strength and large rigidity (such as pressure vessels, pipes, boilers, etc.).
