At what humidity does LR AH40 shipbuilding structural plate rust?

The company has allocated special environmental protection facilities for all LR AH40 shipbuilding structural plate pollution sources, strengthened the recycling of waste resources and improved the efficiency of resource utilization. At present, the recovery and utilization rate of solid wastes such as iron slag, steel slag, iron bearing dust, LR AH40 shipbuilding structural plate steel mill scale, environmental protection dust has reached 100%.

Manganese steel vs carbon plateManganese steel and ordinary steel belong to carbon structural steel and low alloy structural steel. The difference between manganese steel and LR AH40 shipbuilding structural plate is different in compressive strength, strength and main purpose. In terms of compressive strength, the compressive strength of manganese steel is higher than that of ordinary steel plate. In terms of strength, the strength of manganese steel is also higher than that of carbon steel, and in terms of application, manganese steel plates have more prominent advantages due to the advantages of materials, so the application areas are more common.

Corrosion resistant steel prices are generally higher. What are the applications of LR AH40 shipbuilding structural plate, corrosion resistant steel? First, the corrosion resistant steel can be used in chemical containers, such as furnaces. Some chemical products have strong corrosivity and need steel with excellent corrosion resistance, otherwise they will be easily corroded. Second, the corrosion resistant steel can be used for sewage pipelines. Industrial sewage pipelines need to discharge a large amount of wastewater, which may contain harmful substances.

Phosphorus is a very harmful element in LR AH40 shipbuilding structural plate steel. With the increase of phosphorus content, the strength, flexion ratio and hardness of LR AH40 shipbuilding structural plate steel increased, but the plasticity and toughness decreased significantly. In particular, the lower the temperature, the greater the impact on plasticity and toughness, increase the cold brittleness of steel.
