Benefits

Why Supra range

  • Austenitics are highly formable and weldable and used in facades, claddings, storage tanks, and heat exchangers.
  • Our Supra range includes the well-known Outokumpu Supra 316L/4404 as well as several alternatives and is home of our latest austenitic stainless steel grade innovation: Supra 316plus.
  • Ferritic stainless steels are nickel free, have good formability, and can be used in applications with elevated temperatures.

Attributes

  • Supra 316/4401 is a widely used Molybdenum alloyed stainless steel and an all-purpose product with very good corrosion resistance
  • Supra 316L/4404 is a low-carbon alternative to Supra 316/4401 since the lower carbon content minimizes carbide precipitation, giving improved resistance against intergranular corrosion.
  • Both versions are suitable for a wide variety of applications that require good formability and weldability.
 

Supra range

Our Supra range austenitics can be readily formed by all cold forming methods. These products are mainly used in facades, claddings, storage tanks, and heat exchangers.

All grades share common forming properties such as excellent stretch formability, a high work-hardening rate as well as an average strain ratio r of approximately 1. The stability of the austenite decreases with lower alloying element content; more martensite is formed during cold working. In addition to the chemical composition, the martensite transformation depends on the forming temperature.

乐游手游官网下载 Due to their high toughness and work hardening behavior, austenitic steels are more difficult to machine than carbon steels but are still comparatively easy to machine compared to more highly alloyed stainless-steel grades. They require higher cutting forces than carbon steels, show resistance to chip breaking, and have a high tendency to built-up edge formation. The best machining results are obtained by using high-power equipment, sharp tooling, and a rigid set-up.

low interstitial levels and added stabilizers have made enormous improvements to the welding characteristics of ferritic stainless steels. in addition, due to their lower thermal expansion and higher thermal conductivity, distortion and buckling is much lower during welding compared to austenitic or duplex stainless steels.
