The company Electrovek-steel offers the delivery of bulk rolled steel 1.4511, aisi 430Nb at a bargain price from the manufacturer, ensuring delivery to any point specified by the customer. Buy steel grade AISI 430Nb (1.4511) from Electro-steel-steel can be in a wide range of lengths, profiles and diameters.
Composition and properties
Stainless low-carbon steel AISI 430Nb with the presence of niobium is produced in accordance with ASTM standards (USA), UNS euronorms, and also in accordance with Russian GOST 5632 .
The composition of this steel produced abroad is shown in the following table:
|Content in steel,%||Not above 0.05||Not above 1.0||Not above 1.0||16… 18||0.35… 0.6||Rest|
The material is well suited for hot volumetric stamping on falling hammers and hot stamping presses. Heat treatment after rolling is possible, and is performed with the aim of increasing the surface hardness of the original mill and reducing the grain size in the microstructure. High resistance against the development of corrosion phenomena is maintained at operating temperatures of products up to 500 0 C. The recommended mode of high-temperature annealing is aging at temperatures of 750… 800 0 С, followed by cooling in an oven or in calm air. Normalization steel AISI 430Nb (1.4511) is ineffective.
The homogeneity of the physicomechanical parameters of the steel in question does not depend on the method of its melting. Therefore, the material can be obtained by various technologies — fusion in conventional furnaces, electric arc and electrovacuum methods. In the latter case, vacuum degassing is simultaneously carried out, which increases the homogeneity of the structure, and reduces the number of nonmetallic inclusions.
Metallurgical enterprises of the European Union, this steel is produced under the brand X3CrNb17, and differs slightly more rigid tolerances for the carbon content: it should not be more than 0.03% in the steel. The closest domestic analogue is the heat-resistant alloy 0X17N5G9AB. It is produced according to the specification of the enterprise, and has the following composition:
|Content in steel,%||Not more than 0.08||Not higher than 0,8||Not higher than 0,8||16… 18||Up to 0.8||Up to 4.5… 5.5|
Due to the increased content of niobium, the AISI 430Nb (1.4511) steel is distinguished by its high heat resistance. This allows the use of volumetric parts made of wire, rod or pipes in the working parts of pipelines and pipeline fittings that constantly come into contact with chemically aggressive media in a heated state up to 450… 500 0 С.
The ductility of the steel in question is satisfactory, although it is more expedient to subject the semi-finished products that are difficult to form to a hot pressure treatment. When processing in the cold state, the processing tool is made of high-speed steels, and between the transitions, softening annealing is provided. Heat-resistant alloy 0X17N5G9AB due to the presence of nickel, has increased machinability.
To buy stainless low-carbon steel AISI 430Nb (1.4511) with increased content of niobium, and in the delivery condition the circle, wire, pipes from Electrovek-Steel company is very profitable. Rolling stock is characterized by stability of all dimensional characteristics, and for each lot is attached the corresponding certificate of quality.
