Stainless Steel Cutting Ability Performance Properties
Different cutting stainless steel is very different. In general cutting stainless steel worse than the other, is the difference between the cutting performance of austenitic stainless steel. This is due to severe work hardening of austenitic stainless steel, low thermal conductivity caused. To do this in the cutting process cutting the need to use water-based coolant to reduce the cutting heat deformation. Especially when the welding heat treatment is bad, no matter how improved cutting accuracy, the deformation is inevitable.
Other types, such as martensitic stainless steel, ferritic stainless steel cutting of stainless steel is not quenched as long as the cutting, then with the carbon steel is not much different. However, the higher the carbon content of both is the cutting performance is worse. Precipitation hardening stainless steel because of its different organizations and different treatment methods and shows the cutting performance, but in general the cutting in the annealed state with the same series and the same strength martensitic stainless steel and austenitic stainless steel.
To improve the cutting performance of stainless steel, carbon steel and can be added as sulfur, lead, bismuth, selenium and tellurium and other elements to achieve. Add, such as sulfur, selenium and tellurium and other elements can reduce tool wear, lead and bismuth and other elements added to improve cutting conditions.
Although the sulfur added to improve the cutting performance of stainless steel, but because it is based on Mns compounds in the form of steel, so make the corrosion resistance decreased significantly. To address this problem, usually a small amount of molybdenum and copper.
