A Simple Guide To Stainless Steel

Understanding Stainless Steel Grades And Their Uses

Stainless steel comprises of iron alloy with a minimum of 10.5% chromium, the chromium produces a thin layer of oxide on the surface of the steel (passive Layer) this prevents corrosion of the surface. By increasing the amount of chromium the more corrosion resistant the stainless steel.

Other metal elements such as Nickel, Molybdenum, Titanium and Copper, along with non-metal additions such as Carbon and Nitrogen are added to enhance formability and strength

It always important to choose the particular grade of stainless steel suited for purpose of use.

A good general rule is 304 Grade for indoor and 316 Grade for outdoor.

In Our Opinion

AISI 304 Grade, A2 Stainless Steel

Internal Use

Dry Environments

Good Corrosion Resistance

Ideal for: Interior Balustrade, Handrail, Internal Door Furniture, Shelving Supports, Interior Wire Rope and Rigging

In Our Opinion

AISI 316 (Marine) Grade, A4 Stainless Steel

External and Internal Use

Wet and Humid Conditions

Salt Water Environments

Excellent Corrosion Resistance

Ideal for: Exterior Balustrade, Handrail, Garden Trellis Systems, Wire Rope Assemblies, Catenary Wires, Door Furniture, Turnbuckles, Exterior Rigging, Marine Shackles and Hardware

Specialist Stainless Steels

Duplex and 2205 grade stainless steel is ideal for highly corrosive marine environments and offer a higher mechanical strength.
