For Greater Hardness and Strength
The Dura range contains 14 martensitic and precipitation hardening stainless steel products designed for applications that demand a high level of surface hardness.
In addition to improved hardenability, these products are characterized by high strength and wear resistance attributes. For this reason, the main alternatives to the Dura range products are carbon steels rather than other ranges of stainless steel.
Dura range products are sold as solution annealed and then age hardened for use in applications that require hardness and a higher corrosion resistance than carbon steel can offer. These products are applicable to everything from high quality knives and scalpels all the way to aircraft landing gear. The precipitation hardening products are hardened by a special mechanism involving the formation of precipitates within the microstructure. Both martensitic and precipitation hardening stainless steels are magnetic.
Our Dura range is especially suitable for end products, which require heat treatment. In the case that you’re needs are geared towards high-strength stainless steels with no heat treatment requirements, our Forta range’s temper rolled products are suitable for those needs.
All Dura range products are readily available around the globe and are delivered from mills that are well known for their on-time delivery accuracy. You can depend on Outokumpu stainless steels to reliably and consistently meet the specifications that your application demands. Our experts can also create products that are custom-made to your precise specifications.
Dura range stainless steels meet the following standards:
| ASME SA240M Code Sect. II. Part A |
| ASTM A240/A240M |
