Stainless Steel

Stainless steel machining is an art form. When you need top quality stainless steel machining, you need Yorke Precision. Stainless Steels will always machine slower than Aluminum, but what you lose in machinability you gain in durability. Below you will find a list of the different types of stainless steels that we specialize in. Remember that stainless steels have different amounts of chromium added to them in order to resist rust, but that this makes them generally less tough than regular Steel.

Alloy Types:

200 Series – Austenitic iron-chromium-nickel-manganese alloys.
300 Series – Austenitic iron-chromium-nickel alloys.
Type 301 – Highly ductile, for formed products. Fast hardening while is being machined.
Type 303 – Free machining version of 304 via addition of sulfur.
Type 304 – Very popular; also referred as 18/8 stainless steel.
Type 316 – Very common and highly used by the sea industry due to its resistance to saltwater.
400 Series – Ferritic and martensitic alloys.
Type 408 – Heat-resistant; poor corrosion resistance; 11% chromium, 8% nickel.
Type 409 – Most affordable one; used in the automobile industry.
Type 410 – Martensitic (high-strength iron/chromium).
Type 420 – Known as “surgical steel”.
Type 430 – Used in vehicle trims, decorative.
Type 440 – Great cutlery quality, better edge retention due to its high carbon content.
600 Series – Martensitic precipitation hardening alloys.
Type 630 – Better known as 17-4.

Exotic Series

S35VN – This is a superior knife steel, and holds a keen edge longer than any other known steel.
