Stainless Steel & Its Alloys
Ultra-thin at tight tolerances
Arnold’s Precision Thin Metal business provides many types of high quality stainless steel, rolled to precise tolerances for thinness and flatness. Its excellent corrosion resistance and good workability make stainless steel the obvious choice in numerous applications across many markets. From commercial and defense aviation devices to tiny precision instruments and components, to large area solar panels and other energy generation and management apparatus, as well as a range of commercial and automotive uses, Stainless Steel is a versatile choice.
Stainless steel grades are particularly responsive to various heat treatments and can be readily drawn and shaped to provide thin-walled tubing, hypodermic needles, and other precision devices for medical applications.
Arnold offers cold-rolled stainless steel in a number of grades, including those listed below.
