EN 10025-6 high strength steel 1.8931 chemical composition and properties

Advantages of hot rolling: hot rolling can destroy the casting structure of ingot, refine the grain of steel and eliminate the defects of microstructure, so that the steel structure is dense and the mechanical properties are improved. This improvement is mainly reflected in the rolling direction, so that the EN 10025-6 high strength steel 1.8931 steel is no longer isotropic to some extent; the bubbles, cracks and looseness formed during pouring can also be welded under the action of high temperature and pressure.

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.

As a leading steel supplier of raw material, BBN steel company is committed to serving the majority of manufacturing, ships building, construction, power plant, oil storage, and mining companies. With a good reputation, perfect sales network and thoughtful after-sales service, customers have spread to more than 70 parts of the world.

Flat steel is a kind of steel with rectangular cross-section and blunt edges at the edges and corners. It is usually 12-300 mm wide and 3-60 mm thick. Compared with EN 10025-6 high strength steel 1.8931 ordinary steel plate, the utilization rate of flat steel is increased by one to five percentage points. Moreover, flat steel can be produced with fixed thickness, width and length according to the user's requirements, which saves the cutting process for users, reduces the consumption of labor and materials, and also reduces the processing loss of raw materials, saving time, labor and material.
