Weldability
Suitable welding methods for Sanmac grades are manual metal arc
welding with covered electrodes MMA and gas shielded arc welding,
with the TIG and MIG methods as first choice. During TIG welding,
especially autogenous welding, a correct setting of the welding current is of great import­ance. However, when filler metal is used, the
weldability is the same as for the standard material.

The art of machining stainless steel
Austenitic and duplex stainless steels have properties that give
them a different machinability compared to carbon steel or
ferritic and martensitic stainless steels. The greatest difference
is the high ductility of austenitic and duplex stainless steels, as
well as their tendency to work harden and form built-up edges
on the cutting tool. Moreover, in duplex materials, chip forming
is made more difficult by the high strength of these materials.
In Sanmac® materials, machinability has been improved without
jeopardising properties such as corrosion resistance, mechanical
strength nor weldability.
The non-metallic inclusions in Sanmac steels are of great significance to the improved machinability. In addition to sulphides,
Sanmac steels contain oxide inclusions that improve chip breaking and reduce tool wear.
Apart from the material and tool, the machining result is influenced by the machine itself, by the cutting data, coolant, and
type of operation.
Always observe the following:
• Use modern cutting tools with suitable geometries for
machining austenitic and duplex stainless steels.
• Change the insert regularly. A worn insert causes
more severe work hardening.
Strength
High strength in combination with high ductility in austenitic
and duplex stainless steels makes chip breaking more difficult
and increases the risk of vibration, which damages the surface
and reduces the service life of the insert.
Always observe the following:
• Use stable machines only.
• Make sure that the workpiece is prop­erly secured and
use stable tool holders.
• Try to minimise tool overhang – this is especially
important in drilling and internal turning.
• In case of vibrations, often a problem during internal
turning, use tools with small nose radius even though this
increases the risk of plastic deformation at the nose.
To obtain long insert/tool-life with good chip breaking when
turning, a generous flow of cutting fluid should be used. The
cutting fluid removes heat from the chip and facilitates chip
breaking, at the same time giving improved dimensional stability. In the case of internal machining, chip evacuation is
improved if cutting fluid is applied through the cutting tool.
Cutting data recommendations
Work hardening
All inserts geometry and grades are valid for Sandvik Coromant.
In all machining that involves cutting austenitic and duplex
stainless steels, work hardening is more pronounced than in
carbon steel or ferritic and martensitic stainless steels. The
machined surface becomes harder at the same time as tool-life
decreases.
Coromant, CoroMill, CoroDrill, T-Max are trademarks owned by Sandvik Intellectual
Property AB.
The recommendations are based on machining with modern
CNC ma­chines with normal power and speed ratings. When
changing the cutting data to compensate for external factors,
only small changes in feed should be made. Recommended toollife is 10–15 minutes unless otherwise stated.

The areas are limited in the
event of low feeds because of
unacceptable chip breaking. In
the case of high cutting speeds, plastic deformation is the most
dominant cause of failure. When feed increases and the cutting
speed falls, edge frittering (chipping) increases significantly.
The diagrams are applicable for normal cutting times. For long,
continuous cuts, the cutting speeds should be reduced somewhat.

Types of wear
Thread cutting
The most important types of wear in general turning of stainless
steels are flank wear, plastic deformation, frittering (chipping) and
notch wear.
Indexable inserts can be used for external thread cutting in all
diameters. Threading with screw-cutting dies or die heads is cost
effective only for small diameters. For inter­nal threading with short
and normal cutting lengths, thread cutting with indexable inserts
is recommended from hole diameter 12 mm (0.47 inch) and up.
For long cutting lengths, thread cutting with indexable inserts is
recommended for hole diameters above 20 mm (0.79 inch).
Flank and notch wear
Causes: a) Cutting speed too high, or insert has insufficient
wear resistance. b /c) Oxidation or excessive attrition wear.
Solutions: a) Reduce the cutting speed. Choose a more
wear resistant insert grade. b /c) Reduce the cutting­
speed. Choose a smaller entering angle.
Plastic deformation
Cause: Too high insert temperature in combination
with high pressure.
Solution: Choose a more wear resistant insert grade.
a) Edge depression. Reduce the cutting speed.
b) Flank impression. Reduce the feed.
Built-up edge
Cause: Workpiece material welds progressively
onto the insert.
Solution: Increase the cutting speed.
Edge frittering (chipping)
Causes: Too brittle insert grade, too weak insert
geometry or built-up edge.
Solutions: Choose a tougher insert grade, choose
an insert with a stronger edge or, in case of built-up
edge, increase the cutting speed.

Due to the tendency of austenitic and duplex stainless steels to work
harden, radial infeeds are recommended. A generous flow of cutting
fluid should be used, partly to obtain a reliable pro­cess and partly to
guide the chips. The recommendations apply for a tool life of 30 minutes for the austenitic material and 10 minutes for the duplex material. T-Max® U-Lock is Sandvik Coromant’s thread turning system.

Milling
Dry milling is the first choice when milling austenitic and duplex
stainless steels. When engaged in a cut the cutting edge is strongly
heated, followed by cooling down when exiting the cut. Use of cutting fluid causes a more rapid cooling of the insert, which can result
in a reduced tool-life due to thermal cracking of the edge.
When milling austenitic and duplex
stainless steels it is import­ant to choose
a correct combination of milling cutter
system, insert geometry and grade, together
with appropriate cutting data.
If cutting fluid is needed (e.g. when the surface finish can not be
reached in the dry condition) the cutting speed must be reduced by
approximately 40-60 % to prevent tool wear due to increased thermal load on the inserts. When used, cutting fluid should be supplied
in large amounts around the cutting edges throughout the process.
Use of appropriate cutting data means
that milling is carried out at cutting speeds
above the range where there is a risk of
built-up edge formation.

Parting-off and grooving
Sawing
The recommendations for parting-off
and grooving are applicable to most
types of grooving operations in stainless steel materials. The feed should be
chosen according to the width of the
groove. The lowest feed value should
be selected for the smallest groove
width. Sandvik Coromant’s system for
parting-off and grooving is CoroCut®.
Both band sawing and cold (circular)
sawing are ideal for cutting Sandvik®
steels.
If there are requirements on smooth
surfaces or if small sections are to be cut,
cold sawing is preferable. Band sawing
is the more flexible approach, as it can
cover a larger variety of sections and
sizes. It is also the most cost effective,
especially when using bimetal blades
suited for stainless steel sawing.

Alternative geometries when using T-Max Q-Cut inserts are -5F to prevent
problems with vibrations and -4E under unstable conditions. Corresponding
alternatives for the CoroCut system are -CF in case of vibrations and -CR at
unstable conditions. Cutting data as above.
For ultimate productivity in high-speed cutting and lower cost per
cut, it is recommended that cemented carbide tipped blades suited for
stainless steel sawing are used.
Tooth pitch (TPI) should be selected according to the dimensions of
the material to be cut.

* Higher cutting speed can be used for Sanmac® 4305.
* For duplex and super-duplex the lower speeds and removal rates should be
chosen. For larger dimensions a slight decrease in band speed, in combination with an unchanged removal rate, is recommended.
Recommendations are for guidance only, and the suitability of a material for a specific
application can be confirmed only when the actual service conditions are known.
Continuous development may necessitate changes in the technical data without notice.
