Strength and Resistance Combined

Stainless steel is a family of iron-based alloys containing a minimum of 10.5% chromium. It is the chromium content that creates a passive, self-healing oxide layer on the surface of the steel, providing its famous "stainless" quality and exceptional resistance to rust and corrosion.

Common Stainless Steel Grades We Work With

304/304L Stainless Steel

The most widely used stainless steel grade in the world. It offers excellent corrosion resistance in a wide range of environments. The "L" grade has lower carbon content to improve weldability. It is used extensively in kitchen equipment, food processing, and architectural applications.

316/316L Stainless Steel

Similar to 304, but with the addition of molybdenum. This significantly increases its resistance to corrosion, particularly against chlorides and other industrial solvents. This makes 316L the material of choice for medical devices, marine hardware, and chemical processing equipment.

303 Stainless Steel

This grade has added sulfur, which makes it much easier to machine than 304 or 316. It is a "free-machining" grade chosen for high-volume production of small, complex parts like nuts, bolts, and fittings where corrosion resistance is still needed, but machinability is a top priority.

Stainless Steel FAQ

Is stainless steel magnetic?

It depends on the grade. Austenitic grades like 304 and 316 are generally non-magnetic in their raw state. However, cold working (like bending or machining) can induce some magnetism. Ferritic and martensitic grades (like 430 and 440) are magnetic.

What surface finishes can be applied to stainless steel?

Stainless steel can be finished in many ways. It can be left with a standard "as machined" finish, bead blasted for a uniform matte look, brushed for a directional grain, or polished to a mirror-like finish. It can also undergo passivation, a chemical treatment that enhances its natural corrosion resistance.

Is stainless steel difficult to machine?

Compared to aluminum or mild steel, stainless steel is more challenging to machine. It is tougher and work-hardens quickly, which requires more rigid machines, specialized tooling, and slower cutting speeds. Our machinists have the expertise to effectively machine all common grades of stainless steel.
