Electrovek-steel company supplies sheet metal products — ribbons and sheets — from heat-resistant steel (1.4511) AISI 430Nb. You can buy this steel at a bargain price from the manufacturer, at the same time the parts of the purchased lot are provided to any place that is stipulated by the conditions. Acquire steel AISI 430Nb (1.4511) from Electro-steel-steel can be in a wide range of thickness and length profile.
Composition and properties
Low-carbon stainless steel AISI 430Nb (1.4511) is favorably distinguished by the presence of niobium in its composition. Its production is carried out according to North American standards ASTM, UNS-norms of the European Union, and also on technical requirements of GOST 5632 (Russia).
The composition of steel AISI 430Nb (1.4511) corresponds to the following:
|Percentage||Not more than 0,05||Not more than 1,0||Not more than 1,0||16… 18||Within the limits of 0.3… 0.6||Rest|
Rolled steel is produced both in the cold and in the hot state (the latter method produces a rolling thickness of 20… 200 mm). The range of produced sheet length is 2000… 6000 mm. Thin sheets and ribbon width 915… 1524 mm are produced in the cold state. At the request of the customer, the rolling can be pre-annealed. After annealing, the steel structure is leveled, and becomes more meleozernistoy, which has a positive effect on machinability. In this condition, the steel AISI 430Nb (1.4511) can undergo a deep multi-transitional stretching and bending. Punching-cutting is performed without chips and metal breaks, it is possible to consistently deform metal in the tape on automated equipment.
Steel can be supplied to the customer after carrying out high-temperature annealing, which consists in heating the sheet metal to temperatures of 750… 850 0 С, followed by slow cooling. Normalization of steel AISI 430Nb (1.4511) does not lend itself.
The European analogue of the steel in question is the alloy X3CrNb17, which differs slightly in the allowances for carbon content: not more than 0.03%. The nearest domestic analogue of this steel is the heat-resistant alloy of grade 0X17N5G9AB, which is produced by special technical specifications of the enterprise. Chemical composition of the alloy:
|Percentage||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|
Iron is the rest.
Due to the presence of niobium in its composition, the steel grade AISI 430Nb (1.4511) has an increased long-term heat resistance. Therefore sheet metal parts made of steel are installed in control and measuring units of equipment, sensors and other technological units that are used in aggressive chemical environments and at elevated temperatures. The rigidity and chemical homogeneity of the surface of the products from the sheet and tape is preserved at temperatures up to 450… 500 0 С.
The field of practical application of the domestic analogue — alloy 0X17N5G9AB — is somewhat wider, due to its increased plasticity and the possibility of punching more complex contours. At the same time, the production cost of the 0X17H5G9AB alloy is substantially higher than the AISI 430Nb (1.4511) steel.
To buy low-carbon stainless steel sheet steel AISI 430Nb (1.4511) is expedient and profitable. Products at a price from the manufacturer, which is offered by Electrovek-Steel, always has high quality and stability characteristics. Each batch of supplied flat products is certified.
