Stainless steel
Corrosion resistance, moldability and precision.
Rostfritt stål har ett motstånd mot korrosion då det innehåller krom som bildar en tunn hinna av kromoxid på ytan. Man brukar ange en kromhalt på min 12-13 % för att stålet skall räknas till de rostfria stålen. Det gör det väl lämpat att användas i miljöer där det kan utsättas för yttre påverkan av fukt, syror, värme etc.
Choose the right stainless steel
It is important that the correct stainless steel material grade is selected depending on the environment it is exposed to. Severe corrosive environments require higher alloy stainless steels.
Stainless steels can generally withstand higher temperatures, but even in this case, the right material grade must be selected depending on the current temperature range. The material has a surface that many find suitable where the visual aspect is important. It is also hygienic and easy to clean, which means that it is used in the medical, food and automotive industries. In this area, we have stainless spring strips/spring steel, acid-resistant strip steel, hardenable martensitic strip steel and also stainless strips for difficult forming as well as deep drawing. We can supply either in coil, ring, cut lengths or sheets. Cut edge, planed round edge etc. designs, completely according to your wishes.
Our most common stainless steel groups are:
- Austenitic stainless steels.
- Ferritic stainless steels.
- Martensitic stainless steels that are made to order.
You can find material tables further down this page.
Our stainless steel
Austenitic stainless steels
Austenitic stainless steels are alloyed with other metals, such as chromium,
manganese and nickel, among others. The material has good to excellent corrosion resistance
combined with very good weldability and formability. The steel is used
where there are high demands on spring function and high strength.
Austenitic steel is also common where the need for good forming properties
is important, such as in bending and deep drawing. The austenitic
structure has good creep resistance and good oxidation resistance, which makes
them useful in elevated temperatures. Austenitic steels can also
be used in cryogenic applications, i.e. at very low temperatures.
The material is normally non-magnetic, but becomes weakly magnetic in
hard rolling, such as spring steel 1.4310.
Ferritic steels
Ferritic stainless steels have good resistance to stress corrosion cracking in particular and are also magnetic. They have good heat resistance and
resistance to oxidation. They have low carbon content and low or no nickel and do not have the same good formability and weldability as the austenitic ones. Due to their low nickel content, ferrites generally have a lower price than the austenitic ones and are mainly used where good formability and good weldability are of less importance. They are used, for example, for various parts in exhaust systems, commercial kitchen equipment and white goods such as refrigerators and freezers.
Martensitic hardenable steels
Martensitic stainless steels are hardenable and, after hardening, have high hardness
and wear resistance, high yield and ultimate strength. The hardness after hardening
is determined by the carbon content and the heat treatment parameters. It is used
for various types of cutting applications such as knives and
cutting tools, garden tools, surgical instruments, measuring tools, etc. We
provide martensitic steels in both unhardened and hardened condition. As
with hardened carbon steel, the formability of hardened stainless is severely limited. These steels are magnetic.
