Here we would like to take a closer look at stainless steel 1.4762. It is very popular with our customers, as it is particularly well suited to certain fields of application. To help you judge whether a 1.4762 sheet is the right choice for you, we will inform you about its material properties.
From these it also follows where 1.4762 is best used. Sheets made of this material are in particular demand and are among the products most frequently ordered from us. We can also gladly take on cutting and further processing for you - but more on that later.
What is stainless steel 1.4762 composed of?
Since the various alloys essentially differ only in their composition, let us first look at what 1.4762 consists of. It is a ferritic chromium steel with a chromium content of 23.0 to 26.0%. It also contains between 1.2 and 1.7% aluminium. Carbon may account for a maximum of 0.12%, manganese for 1.0%. Silicon must have a share of at least 0.7% and at most 1.4%. Phosphorus and sulphur are present in small amounts at a maximum of 0.04% and 0.015% respectively.
What distinguishes 1.4762 sheet?
It is a heat-resistant steel with outstanding resistance to sulphurous gases. This material is also resistant to sulphurous reducing gases. Its scaling resistance is maintained up to a temperature of 1,150 degrees Celsius.
Compared with heat-resistant austenitic steels, 1.4762 offers design advantages: it has higher thermal conductivity and lower thermal expansion than those steels. It is also more tolerant of fluctuating temperatures, even in the range beyond 650 degrees Celsius.
However, its mechanical properties at high temperatures are not as good. This is why it is only used where mechanical stress is relatively low.
Very good weldability
For further processing it is a decisive advantage that sheet 1.4762 has very good weldability. It can be welded with all common welding processes: TIG, MAG, arc or submerged arc welding all deliver good, reliable results.
In practice, however, workpieces thicker than 3 mm must be preheated; the ideal temperature range is between 200 and 300 degrees Celsius. Thinner workpieces do not need preheating, as they heat up quickly during welding. As regards forming, bear in mind that this stainless steel is only suitable to a limited extent. Here too, workpieces thicker than 3 mm must be preheated to between 200 and 300 degrees Celsius before processing.
Fields of application for stainless steel 1.4762
This steel is used in many places. It is very popular for furnace construction in the high-temperature range. Many parts in the chain industry and in mechanical engineering are also made of this material, because they can be used for a long time. The same applies to furnace construction, where mechanical stress is relatively low compared with thermal stress.
Examples of items made from 1.4762 include gas turbines, thermal protection tubes, exhaust valves and kilns. Soot blowers, air preheaters and heat exchangers are also frequently made from it.
A special material
As 1.4762 is made for special applications, it is a material that is not offered everywhere. This is of course also because every customer needs a sheet in specific dimensions - and cutting stainless steel is not a task an inexperienced craftsman can manage. For DIY stores and metal dealers, it is therefore not worthwhile stocking various stainless alloys such as stainless steel 1.4762: customer demand is too low.
So that you can continue your project requiring this special sheet, you have two options. You can contact a metalworking company - but they tend to prefer large or at least regular orders, so expect them to take their time preparing a quotation.
Or you can turn to us. We not only have decades of experience in processing stainless steel; we are also set up to produce individual sheets for customers, including orders from private individuals.
We are happy to advise you
Even though machines take over large parts of the work at our company, some things are still as they used to be. This includes the value we place on personal advice. For this reason, the only way to order from us is to contact our sales team.
That way we can assure you that we will always find the right sheet for you. Our experienced staff know all the properties of heat-resistant sheet and can determine with just a few questions what the best choice is for you. This naturally also applies to the material thickness, which must vary according to the planned load.
We can quote you the price for your individual sheet during the phone call itself. We take the trouble to calculate every order precisely rather than fobbing you off with flat rates. With us, you only pay for what you actually order.
We can do more than just sheets
Sometimes it takes more than just a sheet in specific dimensions. Even though sheet cutting with lasers and other processes is the core of our company, we offer further services around stainless steel. For example, we can offer to bend sheets for you - interesting whenever you need an L-profile or special stainless steel angles. We can produce all of this in your desired sizes.
We can also treat the surface for you using various processes. If you want to replace the floor plate of your trailer, for example, we can foil-protect it for you. Feel free to ask us whether we can take some work steps off your hands for your project.
We deliver quickly and reliably
Our production is designed to complete every customer order within 48 hours of ordering. Although we are very fast, we make no compromises on quality. We invest continuously in our machines so that we can always use the best processes for working stainless steel.
We exclusively process sheets from European producers and always hold a stock of more than 2,000 tonnes. Only in this way can we react to every order at short notice and get our individually manufactured products to the customer within a few days. Try it for yourself.
