1.4462 (ASTM A182 F51) EU material directly from stock & cut to your required dimensions.
1.4462 is a corrosion and acid resistant austenitic-ferritic chromium-nickel-molybdenum steel that exhibits excellent corrosion resistance against pitting and surface corrosion.
The nickel content is lower than in conventional austenite, making this stainless steel particularly appealing from an economic point of view. Duplex steel 1.4462 is magnetic.
Duplex steel 2205 is used in the construction industry, shipbuilding, the food industry, the chemical industry, mechanical engineering, offshore, electronic equipment and the oil industry.

Properties of 1.4462:
Forging: 1.4462 reacts sensitively to thermal shock loads, which is why it requires slow heating to 1200°C. It can be forged at temperatures between 1200°C - 900°C with subsequent rapid cooling in air or water.
Welding: 1.4462 duplex steel is not easy to weld. Working with unsuitable welding parameters can lead to poor results. The use of higher energy densities (1 - 3 kJ/mm) during welding is recommended to achieve improved phase distribution in the weld zone. This consequently helps to improve the mechanical properties.
Corrosion resistance: 1.4462 exhibits excellent corrosion resistance in acid environments and in media containing chloride (e.g. sea water, steam, nitric acid, sulphuric acid). Regarding intergranular corrosion and stress corrosion, 1.4462 duplex is superior to austenitic steels due to its duplex austenite and ferrite microstructure.
Machining: Due to its dual-phase structure and associated strength properties, 1.4462 can only be machined under difficult conditions. 1.4462 exhibits a smaller range of ideal cutting conditions than austenites. It is therefore advisable to use cermet or coated tungsten carbide plates.
Cold working: According to DIN EN 10263-5, 1.4462 is suitable for cold solid working.
Heat treatment: Hot working must be carried out above the temperature range between 600°C and 900°C because the sigma and other phases reduce toughness and corrosion resistance. Following hot working 1.4462 needs to be cooled rapidly.

flat, forged, pre-machined
The processing with the saw is a mechanical processing of the material, which results in a significantly lower unintended deformation and increased hardness for the existing structure, such as the thermal cutting.
Thus, the machined workpiece has a homogeneous structure even at the edge, which does not change in the continuation of the material.
This circumstance allows immediate finishing of the workpiece with milling or drilling . So it is not necessary to anneal the material or make a similar operation beforehand.
