UNS S40900 Precision Stainless Steel Strip 0.5mm Aluminium Roll width 400mm Slit
Grade 409 stainless steel is a Ferritic steel that offers good mechanical properties and high-temperature corrosion resistance. It is commonly considered as a chromium stainless steel, with applications in exhaust systems of automobiles and applications that demand weldability.
Grade 409 steels are also available in highly stabilized forms, such as grades S40930, S40920 and S40910. The stability of these grades is provided by the presence of niobium, titanium, or both, in the composition of steels.

Used in gas turbine combustors and other key stationary components. Also used for heat treating and industrial heating applications, and in the chemical/petrochemical process industry and in fossil energy plants.
Hastelloy is a superalloy known for its resistance to high temperatures and stress in severely corrosive environments. Forged primarily from nickel, some types of Hastelloy alloys are common in nuclear reactors, chemical reactors and pipes & valves in chemical installations. Hastelloy X is also used for components such as combustion chambers, tail pipes in aircraft and land-based gas turbine engines.
Nickel-based specialty metal Super Alloy Hastelloy X AMS 5536 is the common Sheet and Plate specification.
* Nitronic 60, also considered a Super Alloy, is designed to be the best non-galling stainless steel.
Beryllium Copper: ASTM B194, B196, B197, B534 Copper beryllium alloys are used for their high strength and good electrical and thermal conductivities. There are two groups of copper beryllium alloys, high strength alloys and high conductivity alloys. Beryllium-copper alloys have desirable properties facilitating their use in a variety of demanding applications. The high-strength alloys (C17200 and C17000) are less dense (.298 lbs./cu. in.) than conventional specialty coppers. This often results in a yield of up to 7 percent more feet per pound than high-strength phosphor bronze. The high-conductivity beryllium-copper alloys (C17500 C17510 and C17410) are ideally suited to applications requiring high operating temperatures, or high strength and conductivity.
C17200 Beryllium Copper: ASTM B196, AMS 4533 Most commonly utilized beryllium copper alloy and is notable for exhibiting the highest strength and hardness compared to commercial copper alloys. Its strength and hardness is similar to that of steel. C17200 ultimate tensile and Rockwell hardness properties in a peak aged condition are in the 200 ksi range and RC 45 respectively (electrical conductivity 22% IACS minimum).
C175 - C17500 Beryllium Copper: ASTM B441, ASTM B534 C17500/C17510 offer a combination of high electrical and thermal conductivity with good strength compared to most copper based alloys. C17500 alloy is the mirror image of alloy C17510 in terms of its properties and characteristics. The alloys differ in that C17500 specifies a cobalt alloying addition (2.40-2.70%) and alloy 17510 specifies a nickel alloying addition (1.40-2.20%), but their performance are the same.
