Evek GmbH supplies sheet metal products - bands and sheets - of heat-resistant steel (1.4511) AISI 430Nb. You can buy this steel at a bargain price from the manufacturer, with the delivery of the purchased batch to any location that is agreed upon conditions. You can buy steel AISI 430Nb (1.4511) from Evek GmbH in a wide range of thickness and profile length.
Composition and properties
AISI 430Nb (1.4511) low carbon stainless steel favorably features the presence of niobium in its composition. It is produced in accordance with North American ASTM standards, European Union UNS standards and technical requirements
The composition of AISI 430Nb (1.4511) steel is as follows:
| Chemical element | Carbon | Silicon | Manganese | Chrome | Niobium | Iron |
|---|---|---|---|---|---|---|
| Steel content, % | Not more than 0,05 | Not more than 1.0 | Not more than 1.0 | 16...18 | 0,35...0,6 | The rest |
Rolled steel is produced both in cold and hot condition (the latter method is used for rolling with thickness of 20 ... 200 mm). The product range of sheet length is 2000 ... 6000 mm. Flat sheets and strips with the width of 915...1524 mm are produced in cold condition. At the customer's request the rolled products may undergo preliminary annealing. After annealing, the steel structure evens out and becomes more fine-grained, which has a positive effect on workability. In this condition, AISI 430Nb (1.4511) can be subjected to deep drawing and bending. Punching-embossing is performed without metal chipping and tearing, and sequential deformation of metal in the strip on automated equipment is possible.
Steel can be delivered to the client after high-temperature annealing, which consists in heating of rolled sheet to the temperature of 750-8500 C, followed by slow cooling. The steel AISI 430Nb (1.4511) cannot be normalized.
The European analogue of this steel is alloy X3CrNb17, which has slightly higher tolerance of carbon content: not more than 0.03%. The nearest domestic analogue of this steel is considered to be 0Х17Н5Г9АБ heat-resistant alloy which is produced under special TU of the enterprise. Chemical composition of the alloy:
| Chemical element | Carbon | Silicon | Manganese | Chrome | Niobium | Nickel |
|---|---|---|---|---|---|---|
| Steel content, % | Not more than 0,08 | Not more than 0.8 | Not more than 0.8 | 16...18 | Up to 0.8 | Up to 4,5...5,5 |
Iron - the rest.
Application
AISI 430Nb (1.4511) has an increased long term heat resistance as a result of its alloy niobium content. That's why sheet parts made of this steel are installed in measuring and control units of equipment, sensors and other technological units, which are operated in aggressive chemical environments, and at elevated temperatures. Stiffness and chemical homogeneity of the surface of sheet and strip products are maintained at temperatures up to 450...5000 C.
The sphere of practical application of the domestic analogue - alloy 0Х17Н5Г9АБ - is a bit wider, owing to its increased plasticity and the possibility to stamp more complicated contours. At the same time the production cost of alloy 0Х17Н5Г9АБ significantly higher than steel AISI 430Nb (1.4511).
It is reasonable and profitable to buy low-carbon stainless steel sheet AISI 430Nb (1.4511). Products at a price from the manufacturer, offered by the company Evek GmbH, always characterized by high quality and stability of the characteristics. Each batch of supplied sheet metal is certified.
