Located in the heart of Kinshasa, Congo, Sadiki Metals stands as a trusted partner for industries requiring unwavering quality and resilience. We take pride in manufacturing and supplying high-performance materials built to withstand the most demanding environments, with our Hastelloy rectangular bar being a prime example. This premium alloy is engineered for exceptional service, offering our clients across the region a reliable solution for their most critical projects where corrosion and heat are constant challenges.
The strength of this bar lies in its sophisticated composition, primarily a nickel-chromium-molybdenum blend with additions like tungsten. This specific formulation grants it truly impressive mechanical properties, including high tensile strength and excellent fatigue resistance. It maintains these robust characteristics even when exposed to extreme temperatures, both high and low, ensuring structural integrity and long-lasting performance under pressure that would compromise ordinary steels.

Hastelloy Rectangular Bars are highly resistant to galvanic corrosion due to their corrosion-resistant alloy composition. However, in certain environments with dissimilar metals, they could be susceptible to this type of corrosion.
Yes, Hastelloy Rectangular Bars can be recycled. Their nickel-based composition allows for efficient recycling, making them a sustainable option when properly processed at recycling facilities.
Yes, Hastelloy Rectangular Bars are suitable for cryogenic applications due to their excellent toughness and resistance to brittle fracture at low temperatures, ensuring reliable performance in extreme cold environments.
This unique combination of properties makes the Hastelloy rectangular bar indispensable in a wide range of severe applications. It is commonly machined into essential components for chemical processing equipment, aerospace engineering, and pollution control systems. You will also find it providing reliable service in the oil and gas industry, pharmaceutical manufacturing, and marine environments, wherever exceptional resistance to pitting, cracking, and oxidation is a non-negotiable requirement for safety and efficiency.
