BUMAX AB has launched the BUMAX Ultra range, boasting tensile strengths exceeding 1,700 MPa. BUMAX Ultra is made in BUMAX’s factory in Åshammar, Sweden, and is described as a unique precipitation hardened stainless steel fastener.

“This method has been specifically designed for applications where ultra-high strength, combined with high ductility, is required in the final product. BUMAX Ultra has a corrosion resistance comparable to 316L (A4) and can be used at service temperatures between -50 to 400°C with retained mechanical properties,” states the company.

Despite being a stainless steel, it is frequently used to replace high-strength carbon steel fasteners in critical applications where the requirements on strength and ductility are extreme. “The very high strength to weight ratio, in combination with its good formability and ductility, also make it a very attractive fastener alternative to other lightweight materials, such as titanium,” it added. All fasteners in BUMAX Ultra are custom made and can be delivered with different mechanical properties, with a tensile strength exceeding 1,700 MPa.
