Most people are not even aware that there are different types of stainless steel. They use them - depending on the specification an object is made from - as if it were always the same material.
Yet stainless steel 1.4571 differs from other stainless grades in several respects. Here we take a closer look at what stainless steel 1.4571 can be used for and which properties define it.
What exactly is stainless steel 1.4571?
It is an austenitic chromium-nickel-molybdenum steel stabilised with titanium. One of its most important properties in use is that it is corrosion-resistant. It is used above all where strength is required even at high temperatures.
Its good corrosion resistance in almost all natural waters makes it ideal wherever moisture and liquids are involved - provided the concentration of salt, chloride and hydrochloric acid is not too high. This applies both to private use and to industrial applications where stainless steel 1.4571 is selected precisely for these material properties.
Particularly suitable for high temperatures
Alloying with titanium raises the maximum service temperature of stainless steel 1.4571. It can be used at temperatures of up to 400 degrees Celsius and remains heat-resistant, meaning that a component made from this stainless steel does not deform - even under sustained high temperature.
In return, however, you have to accept that its cold-working characteristics deteriorate: the mechanical properties for cold formability, cold heading behaviour and notched impact toughness are reduced by the titanium stabilisation.
This is why stainless steel 1.4571 is used above all where its temperature resistance is required.
Where is stainless steel 1.4571 typically used?
This steel is frequently used in plant engineering as well as in shipbuilding. The construction industry and the automotive sector also use stainless steel 1.4571 in many ways. Due to its purity, it is also used in production facilities in the pharmaceutical and medical sectors.
It plays an essential role in the food industry, where stainless steel 1.4571 is used above all for the storage and transport of foodstuffs such as milk.
How can stainless steel 1.4571 be processed?
Welding stainless steel 1.4571
It can be welded with all common processes. Filler metal can be dispensed with, and heat treatment is not required when welding stainless steel 1.4571. Care should, however, be taken that interpass temperatures do not exceed 200 degrees Celsius.
Forging stainless steel 1.4571
Provided it is preheated to 1,150-1,180 degrees Celsius, this stainless steel can be forged in the temperature range between 1,180 and 950 degrees Celsius. Subsequent cooling is always carried out with water.
Machining stainless steel 1.4571
If you want to machine stainless steel 1.4571, bear in mind that the addition of titanium increases tool wear.
Stainless steel 1.4571 V2A / V4A: what is the difference?
In everyday life you mostly encounter stainless steel in the V2A version. It is corrosion-resistant and thus meets the requirements of many applications - whether as sheet or as a screw. What can harm stainless steel is chloride-containing substances.
By adding around 2% molybdenum, you obtain a V4A stainless steel. This is considerably more resistant to corrosion in chloride-containing media, which broadens the range of applications. In shipbuilding in particular, but also in the food industry, the V4A version is therefore predominantly used.
What other names is stainless steel 1.4571 known by?
In addition to the designation 1.4571, the steel is also traded internationally under the following names:
- AISI 316Ti
- SS 2350
- ASTM TP316Ti
- UNS S31635
- AFNOR Z6CNDT17-12
- BS 320S17
- UNI X6CrNiMoTi1712
- JIS SUS316TI
- GOST 10Ch17N13M2T
The professional partner for stainless steel 1.4571
As you can see, this stainless steel meets special requirements and is offered in the different versions V2A and V4A. It is therefore clear that this is not a material available in every DIY store. So what can you do if you do not need stainless steel by the tonne?
You need to turn to a supplier that specialises in handling both small and large orders. A supplier like ESC Burg.
We hold a permanent stock of 2,000 tonnes of stainless steel sheet and can therefore guarantee our customers fast order processing. Our self-imposed target is to dispatch every order within 48 hours. We produce individual sheets to customer specification and also offer further processing.
We do not only serve key accounts
Our capacities at the production site in Burg allow large order volumes and we are happy to take on series production. At ESC Burg, however, we have also decided to accept smaller, individual orders around stainless steel sheet.
We offer cutting to individual customer dimensions. Bending or surface treatment can be commissioned at the same time. Our well-trained staff and our machine park ensure that every sheet is produced exactly to the desired dimensions. We guarantee absolutely uniform bends.
Because we purchase very large quantities of stainless steel, we can offer our customers attractive 1.4571 pricing - and we keep our prices transparent. Anyone comparing us with the local metal fabricator will be surprised at how competitive we are despite our fast delivery.
No off-the-shelf products
Anyone with special requirements for a product needs a reliable partner at their side. ESC Burg stands for adherence to deadlines and absolute precision. The stainless steel sheets we produce can be installed without further preparation. Shipping naturally plays a role here too: our first priority is not the cheapest rate, but getting all our products to the customer safely.
For us it makes no difference at all whether we receive an order for 1,000 pieces or a one-off production. Our own standard is to cut every sheet perfectly. We tolerate no deviations, because we know where stainless steel is used: where every millimetre counts.
We do not only process stainless steel 1.4571, but other grades as well. Our friendly staff will be happy to provide information and advice.
As a rule, we process ferritic, austenitic and duplex steel to European standards. By arrangement, we can also source and process steel to foreign standards.
