Material Notes:
ASSAB 618 is a vacuum-degassed Cr-Ni-Mo-alloy steel which is supplied in the hardened and
tempered condition. ASSAB 618 is manufactured to consistently high quality standards with a
controlled sulfur content (max. 0.015%) giving a steel with the following characteristics:
Good polishing and photo-etching properties
Good machinability
High purity and good homogeneity
Uniform hardness in all dimensions
Chemical Composition:
| C | S | Ni | Si | Cr | Mn | Mo |
| 0.37 | ≤0.015 | 1.00 | 0.30 | 2.00 | 1.40 | 0.20 |
High Wear Resistance:
One of the key features of ASSAB 618 steel is its exceptional wear resistance, making it suitable
for applications where tools are subjected to abrasive wear, such as cutting, shaping, and forming
of hard materials.
Good Toughness:
Despite its high hardness and wear resistance, ASSAB 618 also possesses good toughness.
This combination of properties allows tools made from this steel to withstand high impact loads
without fracturing or chipping, making it suitable for demanding applications.
Dimensional Stability:
ASSAB 618 exhibits excellent dimensional stability during heat treatment, meaning that the steel
maintains its shape and size accurately even when subjected to high temperatures. This property
is crucial for ensuring precise and consistent tooling dimensions.
Heat Treatment: ASSAB 618 steel can be heat-treated to achieve the desired hardness and
mechanical properties. Common heat treatment processes include quenching and tempering,
which result in a hardened steel with improved strength and toughness.
Applications:
Injection moulds for thermoplastics
Extrusion dies for thermoplastics
Blow moulds
Forming tools, press-brake dies (possibly flame hardened or nitrided)
Machine or structural components, shafts.
ASSAB 618 steel is widely used in the manufacturing of various cutting tools, such as punches,
dies, shear blades, and forming tools. It finds applications in industries like automotive, aerospace,
metalworking, and plastic molding, where tools are subjected to high wear and require excellent
performance and durability.
