The company Electrocentury-steel offers delivery of bulk products from 1.4511 steel, aisi 430Nb at the best price from the manufacturer, with delivery to any point specified by the client. To buy steel AISI 430Nb (1.4511) from Electrocentury-steel in a wide range of lengths, profiles and diameters.
Composition and properties
Stainless steel low carbon steel AISI 430Nb with the presence of niobium produced according to the standards of ASTM (USA), Euronorm UNS, and according to the Russian GOST 5632.
The composition of the steel produced abroad, in the following table:
| Chemical element | Carbon | Silicon | Manganese | Chrome | Niobium | Iron |
|---|---|---|---|---|---|---|
| The content in steel, % | Not more than 0.05 | Less than 1.0 | Less than 1.0 | 16…18 | 0,35…0,6 | The rest |
The material lends itself well to hot volumetric stamping on the falling hammers and hot-stamping presses. Heat treatment after rolling is possible, and produced with the aim of increasing surface hardness of the source of hire and reduce grain size in the microstructure. High resistance against the development of corrosion phenomena is maintained at operation temperatures of articles to 5000 C. the Recommended mode high-temperature annealing — aging at temperatures of 750…8000 C, followed by cooling in furnace or in calm air. Normalizing steel AISI 430Nb (1.4511) ineffective.
Uniformity of physical and mechanical properties of steel under consideration does not depend on the method of smelting. Therefore, the material it is possible to obtain a variety of technologies — melting in conventional furnaces, electric arc and vacuum tube methods. In the latter case, simultaneously made vacuum degassing, thereby increasing the homogeneity of the structure, and reduces the number of nonmetallic inclusions.
Metallurgical enterprises of the European Union, the steel is produced under the brand name Х3CrNb17, and has a somewhat tighter tolerances on the carbon content of our steel should not be more than 0.03%. The closest domestic analogue — resistant alloy 0Х17Н5Г9АБ. It is produced in THAT enterprise, and has the following composition:
| Chemical element | Carbon | Silicon | Manganese | Chrome | Niobium | Nickel |
|---|---|---|---|---|---|---|
| The content in steel, % | Not higher than 0,08 | Not above 0.8 | Not above 0.8 | 16…18 | To 0.8 | To 4,5…5,5 |
Application
Due to the higher content of niobium in steel AISI 430Nb (1.4511) has high heat resistance. This allows the use of three-dimensional parts are produced from wires, rods or tubes, in the working parts of piping and valves that are constantly in contact with chemically aggressive environments heated up to 450…5000 With the condition.
Plasticity of the considered steel is satisfactory, although complex in the form of semi-finished products it is more expedient to subject the hot pressure treatment. When processing in a cold state, the machining tool are made of speed steel, and between the transitions provide ezuprechnaya annealing. High-temperature alloy 0Х17Н5Г9АБ due to the presence of Nickel, has a high machinability.
Buy stainless steel mild steel AISI 430Nb (1.4511) with a high content of niobium, and in the state of delivery round, wire, pipe from the company Electrocentury-steel is highly profitable. Bulk rental is stable all the dimensional characteristics of, and each party supplied the corresponding certificate of quality.
