THE CAST IRON GRADES

Since the launch of our first Duratomic Technology grades TK2001 and TK1001 for cast iron in 2013 we seized the opportunity to further improve performance and productivity in both grey and nodular ductile cast irons.

TK1501: BALANCED CAST IRON PRODUCTIVITY

TK1501 is the first choice in Nodular Ductile Cast Iron turning providing a wide applicability with the characteristic high wear resistance from Duratomic Technology based coatings. TK1501 shows a very high productivity in roughing and reliable productivity at more limited speeds in demanding applications in both Grey Cast Iron and Steels. For the highest security demand still with Duratomic Technology performance, TK1501 with the new MR9 geometry delivers very good results.

TK0501: HIGH SPEED PRODUCTIVITY IN CAST IRON

TK0501 is the first choice in Grey Cast Iron turning delivering the high productivity level needed in addition to the secure behavior with variations in cast iron batches. TK0501 is capable to deliver long tool life and productivity in ductile cast irons in up to one third of the continuous cut applications it may outperform TK1501. Additionally, TK0501 and MR9 are a good combination for high productivity in interrupted cut applications

APPLICATION AREA

The following chart illustrates the indicative positioning and application area for using TK1501 and TK0501 in cast iron workpieces.

Application area chart

The TK1501 is the first choice in ductile cast iron.TK0501 is the first choice in the grey cast iron area. TK0501 also works well in continuous application in ductile casts. TK1501 can be a better choice at limited speed with bet- ter toughness in demanding grey cast. iron applications.

Note: Combining the TK grades with the MR9 geometry increases their toughness drastically while keeping high wear resistance.
