Turning of stainless steel
Are you interested in turning stainless steel… Supplier Avek Global proposes to buy stainless steel of domestic and foreign production at an affordable price in a wide range. We will ensure the delivery of products to any point of the continent. The price is optimal.
General Provisions
Turning of stainless steels depends on the presence and composition of alloying elements, heat treatment (hardening) and technological processing (forging, casting, etc.). In general, machinability is more difficult in more highly alloyed alloys.
Classification of stainless steels
- Ferritic / martensitic grades;
- Austenitic steel
- Duplex steel (austenitic or ferritic)
Supplier Avek Global proposes to buy stainless steel of any brand of domestic and foreign production at an affordable price in a wide range. We will ensure the delivery of products to any point of the continent. The price is optimal.
Ferritic and martensitic steels
They are processed on lathes in a quenched condition; this imposes additional requirements on the plastic deformation resistance of the insert, but provides a better quality of the final surface.
Austenitic stainless steel
This is the most common type of stainless steel. This group also includes so-called superaustenitic stainless alloys, with a Ni content of more than 20%. To obtain complex profiles and diameter differences, or to eliminate jamming of chips (which is considered the main wear mechanism), carbide cutters are used, while the feed must be small and the depth of insertion of the cutter into the workpiece in one pass is minimally permissible.
Duplex and super duplex stainless steels
They are characterized by increased strength. The higher the mechanical strength, the more difficult it is to process the material. Common wear mechanisms are lateral and crater wear, plastic deformation, chip impact on the tool and its shearing. To prevent plastic deformation of the tool, it is important to monitor and cool the chips. For this, it is recommended to use turning tools with the possibility of an internal supply of a coolant source, preferably with high pressure.
Other factors of turning
When turning stainless steels, always use a cutting fluid. Its use reduces the wear of the tool and the plastic deformation of the workpiece in the cutting area. Due to the wear of the edge, which increases as the material of the workpiece hardens, the process of forming burrs intensifies. To eliminate such defects, the cutting edge of the cutter is sharpened, does not allow radial junctions, and applies increased cutting speeds.
