Located in Pulau Ujong, Singapore, Andre Stainless is a reputable company in the production and supply of high-performance stainless steel products. We deal in various industrial fasteners, among them Stainless Steel 440B Bolts, which are famous for their superior wear resistance, hardness, and durability. Made from martensitic stainless steel of high carbon content, these bolts possess good mechanical strength and fair corrosion resistance, rendering them the perfect choice for applications in harsh industrial settings. It is the mission of Andre Stainless to provide high-quality, dependable fasteners that are up to international standards, offering performance-oriented solutions for industries like engineering, automotive, marine, and chemical processing.
Stainless Steel 440B is high-carbon martensitic stainless steel alloy with about 16–18% chromium, 0.75–1.0% carbon, and minor amounts of manganese, silicon, and molybdenum. Its composition provides 440B bolts higher hardness (up to 58 HRC), tensile strength, and mid-range corrosion resistance in dry and mildly corrosive conditions. The alloy has good wear resistance and resistance to oxidation at higher temperatures. Such characteristics render Stainless Steel 440B bolts suitable for high-load, precision, and elevated temperature applications that demand both dimensional stability and strength under stress.
