We have strengthened and broadened our grade profile for stainless steel milling with the introduction of grade 1040.

1040’s tough micro-grain cemented carbide substrate and thin PVD coating helps resist thermal cracking and chipping. It is a broad grade that works well in dry or wet machining and from roughing to finishing. It can be used in a variety of industry segments, including aerospace, energy, chemical and oil and gas.

Hello, and welcome to the Sandvik Coromant webcast about stainless steel milling.

Sandvik Coromant is strengthening and broadening its grade profile for stainless steel milling with the introduction of grade 1040. 1040 can be used in a variety of industry segments, including aerospace, energy, chemical and oil and gas.

1040 should be your first choice grade for austenitic stainless steels such as 304 and 316; duplex stainless, which are more demanding then austenitics due to their higher chromium content; and PH stainless steels such as 17-4 and 15-5. Shoulder milling with small diameter cutters, and tough or slow-speed applications also call for 1040 for optimal performance.

1040’s tough micro-grain cemented carbide substrate and thin PVD coating helps resist thermal cracking and chipping. It is a broad grade that works well in dry or wet machining and from roughing to finishing.

Along with the grade, insert geometry can enhance or detract from insert performance and tool life. When machining stainless, there is always a benefit to using positive geometries, as opposed to negative. Catering the insert geometry to your application can make for optimal cutting conditions.

When it comes to choosing the right grade for your application, follow this simple chart. 1040 should be your first choice for all-around stainless steel milling; use 2030 when you have large engagements, longer cut times and higher cutting speeds; and use 2040 when you have extremely unstable operations where chipping becomes an issue.

1040 can be found in most of the CoroMill family, from square-shoulder and face milling to profile and slot milling, and its versatility fits all of your milling applications.

In very demanding applications, such as milling over holes in austenitic material, several competitor inserts chipped after two pieces. 1040 on the other hand, maintained optimal performance for 50 percent longer.
