Bumax
Bumax is Bufab's registered trademark, known as the strongest
Stainless Steel fastener in the world. When it comes to quality,
corrosion resistance, high strength, fatigue strength, traceability
and heat resistance, we deliver safety and reliability.
Bumax 88 & Bumax 109
Bumax 88 and Bumax 109 are premium A4 fasteners products in the Bumax family. It is known as a very consistent product that offers higher yield strength, lower amount of inclusions and tighter tolerances in chemical composition compared to standard A4 fasteners.
As a result, Bumax 88 and Bumax 109 offers superior mechanical properties and fatigue resistance, better corrosion resistance in most environments and very low magnetic permeability.
Applications
Bumax 88/109 are used in demanding applications in industries like oil and gas, pulp and paper, marine, petrochemical, energy and many other industries where standard A4 fasteners simply cannot do the job. Bumax products are used for water jets, particle accelerators, sub-sea equipment, pumps, valves, wind turbines, high-pressure equipment, nuclear plants, submarines and many more.
Bumax SDX
Duplex Stainless Steel, also known as Ferrite-Austenitic Stainless Steel, is a family of stainless steel that have two-phase microstructure containing Ferrite and Austenite.
Duplex stainless steel offers many attractive properties.
Applications
Bumax Duplex fasteners are used in many demanding applications that require better corrosion resistance and mechanical properties than Bumax 88/109 (316L, A4).
High alloyed Duplex grades such as Bumax SDX and Bumax HDX are mainly used in the oil/gas, chemical, pulp and paper industries, subsea or other types of applications that are working in tough corrosive environments.
Bumax LDX is mainly used in applications that require similar corrosion resistance as A2/A4, but where it is beneficial with higher strength and better fatigue resistance. Typical applications are large construction projects such as bridges, wind turbines and storage tanks.
