Committed to quality, customer satisfaction, and timely delivery, Adam Stainless caters to various sectors such as construction, automotive, and manufacturing, establishing itself as a trusted source for Stainless Steel 416 fasteners throughout Australia.
The Stainless Steel 416 fasteners from Adam Stainless are crafted from a martensitic stainless steel alloy, primarily made up of iron, 12–14% chromium, along with trace amounts of manganese, silicon, phosphorus, sulfur, and carbon. The addition of sulfur improves machinability while still providing moderate corrosion resistance. These fasteners exhibit impressive mechanical properties, boasting a tensile strength between 500 to 750 MPa, along with good hardness and wear resistance. When properly heat-treated, they achieve enhanced strength and dependable performance, making them ideal for applications that require both durability and machining efficiency.

These sheets contain high corrosion resistance and are available up to 1.2-12mm thickness and width up to 2000mm. They are ideal for high temperature application.
Cold rolled plates of SS 321H possess higher corrosion resistance and are available up to 0.3-6mm in thickness and up to 1500mm in width. They are perfect for applications requiring a smooth finish and high strength.
These plates provide outstanding resistance to corrosion, and come in thickness from 3mm up to 12mm and have sizes of up to 1500mm x 3000mm. Raised pattern surface increases the gripping value, thus commonly used for floor and structural work.
Perforated sheets are extremely resistant to corrosion and can be perforated from 0.5mm up to 20mm in diameter. The sheet thickness is also from 0.3mm up to 3mm. It is used in filtration and ventilation systems.
Shim sheets are resistant to corrosion with a high accuracy level. Thickness is available between 0.05mm up to 3mm, and cut-to-size service is also possible to get precise dimensions for several alignment and spacing applications.
Polished plates have excellent resistance to corrosion, and a reflective finish. These plates are manufactured in thickness range from 3mm to 50mm. The size for these plates up to 2000mm x 6000mm is ideal for aesthetic applications as well as a high-quality surface finish.
