Known for their precision engineering and impressive durability, these nuts are designed to meet strict industry standards, ensuring they perform reliably across a variety of applications. Adam Stainless blends cutting-edge manufacturing techniques with thorough quality control to deliver nuts that resist wear, corrosion, and deformation exceptionally well. Trusted by various industries throughout Australia, their Stainless Steel 420 Nuts are perfect for projects that demand dependable fastening solutions, outstanding strength, and a great mix of hardness and toughness.
These Stainless Steel 420 Nuts are mainly made of iron, featuring 12–14% chromium and up to 0.15% carbon, which classifies them as martensitic stainless steel. This unique composition gives them high hardness, wear resistance, and decent corrosion resistance. They can even be heat-treated to boost their strength and toughness, reaching a Rockwell hardness of up to 50 HRC. With good tensile strength typically ranging from 700–900 MPa, they also boast excellent machinability. These mechanical properties make Stainless Steel 420 Nuts a great choice for environments where strength and durability are crucial, even when faced with moderate moisture or chemical exposure.
