MS1700 shows the highest ultimate tensile strength of this steel group and is currently purposed for automotive roof railing. Otherwise, it is best for applications that require high strength and good fatigue resistance, such as belt line and side sill reinforcements.

When choosing the right cutting parameters to run, most people focus on the speed  which relates to the machine RPM.  This is a mistake!  Focus on on the proper feed per tooth (FPT) first, and then adjust the speed.  Often when a part is programmed, and is being proven out for production, the programmer will choose conservative parameters and encounter chatter.  Chatter is nothing more that part vibration or noise, because the tool is not cutting properly.  Usually, the first response is to slow the RPM and the chatter will go away.  This often works, but this is unproductive.  What has just happened is that by reducing the speed and keeping the feed constant, the FPT has increased.  And most likely the FPT before was too low in the first place and that was what caused the chatter.

Transformation hardening is the process by which steel is heated to extreme temperatures and then is cooled quickly following the austenite phase.

The speeds and feeds formulas are in the bottom of the charts below.  If you follow these guidelines, you will have a much greater success rate in part programming, and you will be milling more efficiently.

This innovative steel grade is intended for safety structural parts for passenger vehicles. One of the main benefits of this grade steel is that it lowers the overall weight of safety structural components in passenger vehicles by over a third. The tensile strength for this MS automotive steel grade is 1300 MPa.

Because of these differences in microstructure, strength is one of the main differences between these two kinds of steels. Austenitic steels are much softer than martensitic steels. MS grade steels do not have austenitic structures, and instead contain higher levels of carbon and small amounts of bainite and ferrite.

ANSWER: Martensite and austenite refer to steel microstructure. They make up two of the four types of stainless steels. With low levels of carbon and high amounts of nickel and chromium, austenitic steels showcase good formability, corrosion resistance, and wear resistance. In their annealed condition, austenitic steels are not magnetic.

Yes, this is one of the four types of stainless steels. The other stainless steels are: austenitic, ferritic, and duplex.

These steel grades showcase qualities that are sought out by vehicle manufacturers. For instance, automotive lightweighting benefits fuel economy, which is one clear advantage these steels offer. Another clear advantage is that the higher strength levels produce crash resistant vehicles that satisfy safety regulations.

The most important aspect of milling with end mills is to run the tool at the proper RPM (revolutions per minute or spindle speed)  and IPM (inches per minute or feed rate).  We have broken these recommendations down into material categories so you can make better decisions with how to productively run your end mills.  Certain high performance mills have very specific running parameters relative to their material families.  We have listed these also as individual recommendations by coating family.  These documents are downloadable in pdf formats by clicking the links below.

This MS grade is one of the strongest high strength steels. It is growing in popularity for its outstanding capability to protect EV batteries and for use in bumper and door beams and reinforcement. Along with MS1700, this grade is considered an automotive lightweighting ultra high strength steel (UHSS).

MS steel grades boast some of the highest tensile strength levels within the AHSS/UHSS group. While other martensite steels are 100% martensite, MS grades are considered part of the multiphase steel group. These steels have a martensitic matrix which includes trace amounts of ferrite and bainite. MS steel grades were specifically introduced to meet the needs of the automotive industry for use in cross members, bumper reinforcement, and side intrusion beams. They showcase ultimate tensile strengths up to 1700 MPa.

We have created an excellent speeds and feeds calculator which incorporates these charts into the calculations.  It generates ranges of SFM or SMM and allows you to decide what SFM is appropriate.  It then automatically calculates the RPM.  Then it gives you a range for FPT and allows you to decide what is appropriate.  Then it automatically calculates the IPM or millimeters per minute (MMPM).  Try it out!  It is easy to understand.
