Why is Stainless Steel Difficult to Machine?

Every manufacturer knows the headache of machining stainless steel. I’ve seen countless projects delayed and tools destroyed because teams underestimated its challenges. The material’s unique properties make it a fortress against conventional machining approaches, leading to excessive tool wear and production delays.

Stainless steel’s machining difficulties stem from its high tensile strength, work-hardening tendency, and low thermal conductivity. These properties cause rapid tool wear, excessive heat buildup, and challenging chip formation during machining processes.

Understanding Work Hardening

Work hardening is perhaps the most significant challenge when machining stainless steel. During cutting operations, the material’s surface becomes harder due to plastic deformation. This creates a vicious cycle – the harder the surface becomes, the more force needed to cut it, which in turn causes more hardening.
