Material
Make and original condition.
HEAT TREATMENT
Heat treatment of parts
Heat treatment mode, zone and control are associated with material and geometry.

HEAT TREATMENT
The hardening mode is related to the material and geometry
SENNAI materials show hardened and cemented series. The specific mode, zone, hardness and layer depth are confirmed for the part; they cannot be transferred between different materials and structures.
WHAT TO CHECK
What to ask before heat treatment
Requirements must be measurable and zone specific.
Work area
Where reinforcement is required.
Properties
The hardness, layer or properties of the core.
Deformation
Allowances and method of subsequent finishing.
HOW THE WORK IS CONSTRUCTED
Control before and after heating
Identification and original dimensions are checked prior to launch. After machining, the required characteristics and suitability of the grinding allowance are assessed.
- Before the processMaterial and prepared geometry.
- After the processHardness and condition of the part.
- Before the finishDeformation and residual allowance.
RESULT
Strengthened part with a finishing task
Heat treatment is not the final result: the working surface must be finished and checked according to the drawing.
- ZoneVerified requirement.
- LayerOnly if included in the task.
- FinishGrinding and final control.
BEFORE AGREEMENT
The heat treatment mode is assigned to the part
Process temperature and time alone do not describe the desired result. Before approval, the steel grade, geometry, working area, hardness, hardening depth and permissible deformation are specified. The sequence takes into account allowances for subsequent grinding and the method of checking the finished surface.
Initial data
Steel, workpiece condition, dimensions and sensitive transitions.
Result
Hardness, zone or layer depth and core properties.
Geometry
Allowable variation and finishing allowance.
Control
Place of measurement, method, sampling and recording of results.
NEXT STEP
Specify material, work area and required properties
Add allowances, layer depth if necessary, and confirmation method.
