Sanmac technology

Sanmac^® is a family of machinability-improved stainless steels, available as bar and hollow bar.

There are different ways to measure productivity and determine cost savings, depending on whether you are close to the machining process, or responsible for purchasing the material.

We have therefore chosen to show six different perspectives, which all highlight the benefits of using Sanmac^® materials.

1. Economy

The aim for any component manufacturer is to maximize the value added time, which will earn profit for operations performed. However, every machine tool should have planned maintenance for set up times and periodic maintenance.

2. Productivity

Five aspects define the productivity in your machines:

High cutting data
Tool-life
Energy consumption
Chip breaking
Surface finish

The total productivity potential for a machining process is all about the interaction between material, cutting tools and machine, where the right material can enable higher cutting data while at the same time prolonging tool life.

3. Material consistency

Minimize downtime
Maximize utilization
Enable standardization
Reduce component costs

A higher volume of desired quality products at a lower cost is therefore expected. But if the raw material used does not have the quality and consistency as the rest of the system, then the whole machining operation will fail to achieve the expected cost-effectiveness. Most often the raw material quality determines the ultimate efficiency of a machining operation.

4. Setup times

Why is a short setup time so important?

Higher machine utilization
Quicker batch changes
Less wastage of trial components
Reusability of cutting data programs

For any producer of machined parts, minimizing the time spent between batches must always be kept to a minimum.

5. Chip breaking

How can we help you achieve better chip breaking?

Machining stainless and duplex stainless steels is a challenge due to the high strength of the material, and chip-breaking is closely related to the microstructure. In our hot working process, we ensure that the material has an even and optimized microstructure throughout the entire length of the bar.

6. Chemical composition

Are there differences between materials, if they all fulfill the same UNS standard?

UNS and EN standards for chemical composition allow a wide tolerance, but at Alleima, we never aim for the lower end of these tolerances like many of our competitors. Instead, we design our chemical compositions for the sweet spot in the triangle of desirable properties: machinability, corrosion resistance and weldability. Once that target composition has been achieved, we land exactly in that spot every time we melt, within very tight tolerances.
