What are the skills in cutting hot rolled BV FH32 marine sheet

Q460D material is a low-alloy ultra-high-strength steel with high hardenability. The critical hardening diameter in oil is 60mm (96% martensite). The steel can obtain high strength after quenching and tempering. The toughness, and can be processed into shape; but the cold deformation plasticity and weldability are low.

Shipbuilding steel plates are used to manufacture the hull of marine and inland ships. High strength, plasticity, toughness, cold bending performance, welding performance and corrosion resistance are required for shipbuilding steel plates. Boiler steel plates are used to manufacture various boilers and important accessories. As the boiler steel plate works under medium temperature (below 350℃) and high pressure, it is also subject to impact, fatigue load and water and gas corrosion. The hot rolled BV FH32 marine sheet, boiler steel plate is required to ensure a certain strength and have good welding and cold bending properties.

Hot-rolled steel sheet / cold-rolled steel sheet: Steel ingots or slabs are difficult to deform at normal temperature and difficult to process. They need to be heated to 1100 ° C to 1250 ° C for rolling. This hot rolled BV FH32 marine sheet rolling process is called hot rolling. Rolling at room temperature is generally understood as cold rolling. However, from the point of view of metallurgy, the boundary between hot rolling and cold rolling should be distinguished by the temperature of metal recrystallization, that is, rolling below the recrystallization temperature is cold rolling; Rolling above the recrystallization temperature is hot rolling.
