What hardness can HAWEN hollow block mould components reach after heat treatment?

For applicable HAWEN mould components, the published surface-hardness reference is approximately HRC 58–62 after heat treatment. The material and treatment process depend on the component, mould structure and production requirements. This reference should therefore be read together with the specification for the particular part being discussed.

Identify the component before comparing hardness

A hollow block mould contains several components with different functions. A question about a forming surface is not necessarily the same as a question about the frame or a supporting part. When requesting a hardness specification, identify the component on the drawing or photograph and describe the area that contacts the concrete. This helps keep the material, treatment and hardness information attached to the correct item.

Hardness alone does not describe the complete mould design or establish a service-life guarantee. Block geometry, the working surfaces and the conditions in which the mould operates also need consideration. An approximate range in a general description should not replace the agreed technical requirements for an individual order.

What to send for technical confirmation

Provide the mould or component drawing, machine model, block section and photographs of the existing part where available. If the enquiry concerns wear, mark the affected area and include the production conditions. Ask for the proposed material, applicable treatment and relevant inspection information to be considered together before the specification is finalized.
