If you’re looking for reliable fastening solutions, Andre Stainless is a name you can trust. Based in Pulau Ujong, Singapore, they specialize in manufacturing and supplying Stainless Steel 420 Bolts that are built to last and handle tough mechanical and structural demands. With a focus on martensitic stainless steels, Andre Stainless crafts SS 420 bolts that offer impressive hardness, decent corrosion resistance, and outstanding wear resistance. Their production process is all about precision and strict quality control, making these bolts perfect for a variety of industries, including engineering, automotive, tooling, medical equipment, and general manufacturing.
So, what exactly are Stainless Steel 420 Bolts made of? They’re crafted from a high-carbon martensitic stainless steel alloy that contains around 12–14% chromium and at least 0.15% carbon. This unique blend allows the bolts to be heat treated, achieving high tensile strength (up to 850 MPa) and hardness levels between 48–52 HRC. While SS 420 provides moderate corrosion resistance in dry or mildly corrosive settings, it truly shines in terms of wear resistance and mechanical durability, making it a go-to choice for high-stress fastening tasks.
