what is HARDO X400 equivalent steel grade

    
    HARDOX 400 is a wear-resistant steel plate produced by Swedish company SSAB for the construction and industrial application. It is a high strength quenched and tempered alloy steel that offers a hardness of approximately 400 Brinell and a good balance of strength, ductility and weldability. It has a nominal hardness of 400HBW and a minimum hardness of 360HBW.
    
    HARDOX 400 is a martensitic wear-resistant steel with an average hardness of 400HBW; it is in the hardox range of high wear resistance steel with a hardness of 400 HBW. It is an incredibly wear-resistant steel designed to stand up to the toughest working conditions.
    
    HARDOX 400 is used in applications with very high wear resistance requirements, such as tipper bodies, agricultural machinery, buckets, cutting edges, used for grain silos, crusher and sieving equipment, conveyor belts, anti-skid plates and chutes, etc.
    
    HARDOX 400 has been shown to offer superior performance over conventional 400 grade steel, including increased wear life and improved formability.
    
    In terms of equivalent steel grades, HARDOX 400 can be compared to ASTM A514 Grade F. This is a high strength low alloy (HSLA) steel grade that has yield strength of 100,000 psi (690 MPa). It has excellent ductility and toughness, as well as good weldability and formability, making it an ideal choice for applications such as tipper bodies, agricultural machinery, cutting edges, conveyor belts, and anti-skid plates.
    
    In comparison to HARDOX 400, ASTM A514 Grade F is slightly less wear-resistant but still offers great mechanical properties. It has higher tensile strength of 130,000 psi (890 MPa) which allows it to be more easily formed and machined without risk of cracking or breaking under stress.
    
    Overall, HARDOX 400 and ASTM A514 Grade F are both high quality wear-resistant steels designed for extreme wear applications. The most significant differences between the two are the hardness, formability and strength. HARDOX 400 is slightly harder, provides greater wear resistance, and has more consistent properties than ASTM A514 Grade F. However, the latter still offers good mechanical properties and is the preferred steel grade for applications where formability and weldability are desired.
