Can stainless steel be CNC machined?

Stainless steel has a series of characteristics such as excellent corrosion resistance, formability, compatibility, and toughness over a wide temperature range, and is commonly used for CNC machining and CNC turning in the aerospace, automotive and marine industries.Generally, 303 stainless steel and 304 stainless steel are used for stainless steel milling.

What kinds of materials are stainless steel? Which one is the best?

— Ferritic stainless steel

Ferritic stainless steel is the most common type of stainless steel, with a chromium content of 11% to 30% and a body-centered cubic crystal structure.

This type of steel has the characteristics of large thermal conductivity, small expansion coefficient, good oxidation resistance and excellent stress corrosion resistance. However, it has the disadvantages of poor plasticity, significantly reduced post-weld plasticity and corrosion resistance. Therefore, this kind of stainless steel material is mainly used to make corrosion-resistant parts.

— Austenitic stainless steel

Austenitic stainless steel is a stainless steel material with stable austenite structure inside. This kind of stainless steel material belongs to the product with good comprehensive performance, which can resist the corrosion of various media. And it has high toughness and plasticity, but the strength is low, it is impossible to strengthen it through phase transformation, and it can only be strengthened through cold working. At the same time, its free cutting performance is also very good.

— martensitic stainless steel

Martensitic stainless steel is a kind of stainless steel whose mechanical properties can be adjusted by heat treatment. The hardness after quenching is higher, and different tempering temperatures have different combinations of strength and toughness. At present, this kind of stainless steel material is mainly used in the production of steam turbine blades, surgical instruments and other products.

—Austenitic--ferritic duplex stainless steel

Austenitic-ferritic duplex stainless steel is a stainless steel product with a half internal austenite and half ferrite structure.

It has the characteristics of austenitic stainless steel and ferritic stainless steel, and compared with ferritic stainless steel, it has higher plasticity and toughness, no room temperature brittleness, and significantly improved intergranular corrosion resistance and welding performance. It maintains the brittleness and high thermal conductivity of ferritic stainless steel, and has the characteristics of superplasticity. Compared with austenitic stainless steel, it has better thermal conductivity, smaller expansion coefficient, high strength and significantly improved resistance to intergranular corrosion and chloride stress corrosion. It is a nickel-saving stainless steel.
