Andre Stainless stands out as a top manufacturer and supplier of Stainless Steel 420 Nuts in Pulau Ujong, Singapore. They provide robust and wear-resistant fastening solutions tailored for both precision and heavy-duty applications. With a solid reputation for their expertise in martensitic stainless steels, Andre Stainless crafts SS 420 nuts that are not only heat-treatable but also durable, making them perfect for environments that demand high mechanical strength and moderate corrosion resistance. Thanks to their advanced manufacturing capabilities and unwavering commitment to quality, the company caters to a variety of industries, including engineering, tooling, medical, and automotive, both in Singapore and beyond.
Stainless Steel 420 Nuts are crafted from a martensitic stainless steel alloy that contains around 12–14% chromium and at least 0.15% carbon. This specific blend allows the nuts to be hardened through heat treatment, achieving impressive tensile strength (up to 850 MPa) and hardness levels ranging from 48 to 52 HRC. While they may not offer the same level of corrosion resistance as austenitic grades, SS 420 nuts perform well in mildly corrosive and clean industrial settings, boasting excellent wear and galling resistance.
