Andre Stainless, based in Singapore on Pulau Ujong, has built a solid reputation as a top-notch manufacturer and supplier of high-quality stainless steel products, particularly their Stainless Steel Hard and Half Hard Coils. These coils are crafted using cutting-edge cold-rolling techniques to achieve specific mechanical properties and temper conditions. They’re designed for applications that require a perfect blend of formability and strength, and Andre Stainless makes sure that every coil adheres to strict industry standards for consistency and performance. The company caters to a diverse array of industries, including electronics, automotive, construction, and appliance manufacturing, providing reliable stainless steel coil solutions that meet precise customer needs.
When it comes to Stainless Steel Hard and Half Hard Coils, they’re typically made from grades like 301, 304, and 316, featuring compositions of around 16–18% chromium and 8–13% nickel. In the half-hard state, these coils boast a tensile strength ranging from 750–950 MPa, while the full-hard variants can hit impressive strengths of up to 1,150 MPa or even more. They maintain excellent corrosion resistance and exhibit enhanced yield strength and spring-like qualities thanks to work hardening. These mechanical properties make them perfect for stamping, forming, and other manufacturing processes where precision and strength are essential, all without compromising flexibility.
