Over the years we have developed considerable experience in the machining of stainless steel. Much of this work has been focused on the following market sectors:
We machine all types of stainless steel including 200 & 300 austenitic stainless steels as well as 400 series ferratic/martensitic stainless steels.
These chromium-nickel stainless steels are used for a wide range of applications where features such as corrosion resistance, chemical resistance, strength, weldability and heat resistance are required. In turn they offer their own machining considerations such as rapid work hardening, difficult in making small depths of cut, built up edges, workpiece glazing and dull surface finishes, which we at Markell are fully conversant with.
In response our skilled and experienced engineers are equipped with a full range of techniques for ensuring that our customers jobs are worked to best effect such as increasing lead angles for depth of cut angles, increasing speed for built up edge issues, increasing depth of cut for glazing issues and increased speed & rake and reduced feed for dull surface finishes. Typically our attention to detail results in our customers receiving high quality finished components with consistent tolerances and reduced rejection/scrap rates.
These chromium stainless steels are often used for their hardness, resistance to water, chemical & atmospheric corrosion (including performance under high temperature environments) and mechanical properties. The machining considerations are similar to those of austenitic stainless steel although they generally require higher cutting forces.
