High Temperature Steels

High Temperature Steels

High Temperature Steels, High Temperature Steels Grades, High Temperature Steels Suppliers in India.

Champak Industries is one of the leading manufacturers, exporters and suppliers of High Temperature Steels.

Inferable from its higher resistance to substance and mechanical corruption at raised temperatures, high temperature steels is broadly requested in the market. Because of their attributes, for example, corrosion resistance, oxidation resistance, hydrogen weakness and crawl resistance these are perfect decision for high temperature working situations.

The steel is ordered on the premise of its miniaturized scale structure, which can be ferritic-austenitic (duplex), ferritic, austenitic and martensitic. The structure of steel review is dictated by its synthetic piece.


Classification of Steels Steel Grades Properties Fields of application
Ferritic stainless steel Wnr. 1.4000
Wnr. 1.4016
Wnr. 1.4512
Wnr. 1.4113
etc.
  • Ferritic grades are plain chromium grades (chromium content: 11-17%).
  • They are ferromagnetic.
  • Welding is only under certain conditions.
  • They are easily forged, cold worked and hot worked. They have good machinability.
  • The ferritic stainless steels cannot be used for any reducing or organic acids such as oxalic, formic and lactic, however, it is used where conditions are less aggressive, for handling nitric acid and many organic chemicals in moderately corrosive media.
  • Good resistance to dynamic loading.
  • The grades Wnr. 1.4000 and Wnr. 1.4113 are have good polishing ability and good machinability.
  • Wnr. 1.4016 has good corrosion resistance in the standard environment and at low chloride concentration, e.g. households and natural water. This steel grade is not sea water resistant! It is resistant to intergranular corrosion. In general, Wnr. 1.4016 is poorly suited to welding processes. The material has a good cold formability. For temperatures over 400 degree C not recommended.
  • Soap industry
  • Automotive application
  • Cutlery
  • Household utensils
  • Manufacture of machines and instruments that are exposed to water and water vapor in the long term
  • Food industry
  • Manufacture of surgical instruments
  • Agriculture
  • Construction industry
Martensitic stainless steel Wnr. 1.4006
Wnr. 1.4021
Wnr. 1.4028
Wnr. 1.4057
Wnr. 1.4034
etc.
  • Martensitic steel contain mostly 12 to 18% chromium.
  • Carbon contet: 0,10-0,44 %
  • These materials are ferromagnetic.
  • Martensitic steel can be tempered and hardened by heat-treating.
  • Welding: not suitable or only under specific conditions.
    • The welding of Wnr. 1.4057, 1.4021 and 1.4028 is only permitted if certain precautions were made.
    • For welded structures they are not recommended. Wnr. 1.4034 is not suitable for welding.
  • These steel grades have good ductility and good polishing ability.
  • The martensitic grades are mainly used where hardness, strength and wear-resistance is required.
  • Martensitic grades are not corrosion resistant. However, molybdenum can improve their corrosion resistance.
  • Wnr. 1.4006 is suitable for welding. A subsequent heat treatment is generally required. If it is not performed the corrosion resistance of the steel will be reduced.
  • Wnr. 1.4021 and Wnr. 1.4057 are good for bending, however, Wnr. 1.4028 and Wnr. 1.4034 are not suitable for it.
  • Manufacture of components, devices and instruments that are exposed to large mechanical stresses (e.g. knife)
  • Turned parts
  • Manufacture of surgical instruments and gauges
  • Wear resistant tools for the chemical and food industry.
Austenitic stainless steel Wnr. 1.4301
Wnr. 1.4305
Wnr. 1.4306
Wnr. 1.4541
Wnr. 1.4571
etc.
  • Austenitic steels are the most widely used sort of stainless steel.
  • They have excellent machinability.
  • Welding ability is dependent on the chemical composition of the steel grades, e.g. Wnr. 1.4301, Wnr. 1.4541 and Wnr. 1.4571 are excellently suitable for welding. Wnr. 1.4305 is not recommended for welding, however, this steel grade provides the best machinability.
  • Good ductility for cold and hot forming.
  • Austenitic steel offers excellent corrosion resistance.
  • Under certain conditions these steel grades are non-magnetized.
  • They have a low thermal conductivity.
  • Generally they are resistant to intergranular corrosion.
  • Wnr. 1.4301 and Wnr. 1.4404 have good polishing ability, however, Wnr. 1.4541 and Wnr. 1.4571 are less suitable for polishing.
  • Construction industry (e.g. stainless reinforcing steel)
  • Paper and cellulose industry
  • Wnr. 1.4301: household equipments, tanks, piping, equipments for the dairy industry, bottles
  • Wnr. 1.4571: chemical and textile industry, suitable for high corrosive media
  • Wnr. 1.4541: application is identical to Wnr. 1.4301, however, it is better suited for application with mechanical stress.
Austenitic- ferritic (duplex) stainless steel Wnr. 1.4460
Wnr. 1.4462
  • "Duplex" has a double meaning. Duplex steels have a mixed microstructure of austenite and ferritic stainless steel. The ferrite improves the corrosion resistance. The austenite ensures the toughness, ductility and weldability.
  • In comparison to the austenitic steel duplex steels are better to stretch.
  • They exhibit excellent corrosion resistance.
  • As a result of the industrial development several types of duplex stainless steel have been developed:
    • "normal duplex",
    • "lean duplex",
    • "super duplex",
    • "hyperduplex".
  • Deepwater pipelines
  • Constructions that are exposed to the impact of sea water e.g. bridges, offshore applications
  • Pharmaceutical equipments
  • Plants in the chemical industry
  • Cellulose and paper industry
  • Pressure vessels and tanks.
