SINOXX combines a wide range of stainless steel products.

 

The group is consists of:

  • Austenitic stainless steel
  • Duplex stainless steel
  • Ferritic stainless steel
  • Martensitic stainless steel
  • Participation hardening stainless steel

The diverse applicability of the SINOXX steel brands depends on their chemical composition. A single steel product cannot meet all operational requirements. Thus, under the aegis of SINOXX, various steels have been developed and each of them has only highlighted selected properties. Product durability and usability thus depends quite as much on the selection of an appropriate grade of steel.


Austenitic stainless steel

are the most common. They are no magnetic; in addition to 18 % of chromium, they also contain a minimum of 8 % of nickel that increases their corrosion resistance. This markedly improves by alloying with molybdenum, forming a stable protective passivation oxide layer to provide additional protection. They are also characterised by excellent toughness and the maintenance of mechanical properties at very low temperatures.

Duplex stainless steel

have a typical ferritic - austenitic microstructure in the proportion representing a ratio of 50:50 (commercial grade). The proportion of chromium is around 22 %, nickel amounts to 5 %. These steels types are additionally alloyed with molybdenum and nitrogen. They are characterised by very good mechanical properties, particularly yield strenght and tensile strength. This steel are partly magnetic, and resistant to pitting and stress corrosion cracking.

Ferritic stainless steel

are magnetic with ferritic stainless steels have a low carbon content. The main alloying element is chromium (between 13 % and 17 %); nickel is not added. Their main advantage is resistance to stress corrosion cracking and atmospheric corrosion. They are characterised by a relatively low price, specials steps must be taken into consideration prior during and after fusion welding.

Martensitic stainless steel

have a ferritic structure in the annealed condition or martensite structure in an quenched and tempered condition. Compared to conventional martensitic steel grade, they have improved corrosion resistance. These steels contain between 12 and 15 % chromium and between 0.1 and 0.5 % carbon. By adding molybdenum their corrosion and wear resistance increase. Steels containing between 0.1 and 0.25 % carbon are mostly used in constructions that requires corrosion resistance and enhanced mechanical properties. Steel grades 0.3% or more of carbon are used for cutting tools due to high hardness and wear resistance.

Participation hardening stainless steel

are iron-chromium and nickel alloys characterised by high strength, obtained by precipitation hardening of austenitic or martensitic structure. This enables alloying with one or more alloying elements, such as copper, aluminium, titanium, niobium and molybdenum.
