AISI H11 ESR, steel for hot work and plastic molding applications, stands out for its exceptional physical and mechanical properties. It is manufactured with ESR technology to ensure isotropic properties and low levels of inclusions, making this steel a reliable and durable solution for tools subjected to demanding conditions.
Classified as a chrome-molybdenum-vanadium steel, to ensure its strength in hot work and plastic molding applications, compliance with ASTM A681-08: H11, and equivalence to DIN 1.2343 (X37CrMov5-1), and JIS SKD 6 .
In terms of physical properties, AISI H11 ESR offers thermal conductivity of 27.8 W/m°C and thermal expansion coefficient of 12.7 x 10-6/°C at 400°C, ensuring optimal thermal performance, its mechanical properties at room temperature with hardness of 52 HRC, offers tensile strength of 1,800 MPa, and elastic limit of 1,510 MPa, these values are not mandatory and are Subject to controlled heat treatment processes, they are a general reference to evaluate their performance.
AISI H11 ESR is distinguished by its good hot strength, with excellent resistance to thermal fatigue, good toughness and ductility, its ability to withstand tempering, high hardenability, making it versatile in various industrial applications in hot processes, only available in ESR technology, complies with NADCA #207-2016, offering isotropic properties and low levels of non-metallic inclusions.
For heat treatment, it is recommended after severe machining, stress release, for hardening by transformation to martensite, three tempers, to optimize its properties, it is suitable to receive thermochemical treatments such as nitriding, to provide a hard and durable surface layer. wear-resistant, the H11 ESR is offered as a high-performance solution for hot work tools.
