Corrosion and heat resistance: This
material possesses excellent resistance to a number of aggressive
media including hot crude oil products, steam and combustion
gases When operated in air it is oxidation resistant up to
900°C and with temperature variation resistant up to 800°C.
It is resistant to carbon dioxide up to 650°C.
Welding and mechanical properties: suitable for all
the know welding techniques. It is alloyed with Ti, a carbide
former, and is thus resistant to grain disintegration in accordance
with DIN 50914.Consequetly, irrespective of the cross section
no heat-treatment is required subsequent to welding. The material
is highly ductile. Machine-cutting may only be performed with
very sharp tools otherwise work hardening of the surface occurs
making further processing difficult.
Field of application: Nuclear power (also liquid sodium),reactor
instrumentation, construction of chemical instruments(highly
resistant), in the production of acetyl acid and nitric acid
heat exchangers, annealing furnaces, and textile industry,
crude oil refinement and petrochemistry, fat and soap industry,
food processing, dairy and fermentation work.

Corrosion and heat resistance: Addition
of molybdenum make these steels superior to molybdenum-free
types as regards increased corrosion resistance to certain
acid such as acetic acid, phosphoric acid , sulphuric acid
and other similar acids. Further more these steels are more
or less insensitive to pitting corrosion and withstand salt-water
and aggressive industrial media. They can be used in continuous
operation in air up to approx. 900°C and with temperature
variation up to 800°C.
Welding and mechanical properties: Suitable for all
the known welding techniques, Heat- temperature subsequent
to welding is generally not necessary. In special circumstances
when stresses from welding should be reduced to avoid stress-corrosion-cracking
heat temperature should be conducted (e.g. ½ h at 900°C).
Highly ductile. As with 1.4541 only when sharp tools should
be used for machine cutting. The steels can be polished.
Field application: Due to its high level of resistance
to corrosion and pitting corrosion this alloy is highly suited
to application in the field of chemical instrument construction.
Other fields are : nuclear power plants , reactor instrumentation
, furnace construction , sulphite chemical pulp , textile
, dye , fatty acid, photochemical and pharmaceutical industries.

Corrosion and heat resistance: This
steel is also highly resistance to number of aggressive media
e.g. crude oil products, steam, combustion gases, colouring
agents and liquid sodium. In contrast to alloys such as 1.4301
it is less prone to intercrystalline corrosion due to the
lower carbon contents. It can be subjected to continuous operation
in air upto 900°Cand under temperature variation up to
800°C.
Welding and mechanical properties: Suitable for all
the known welding techniques, Heat- temperature subsequent
to welding is generally not necessary. In special circumstances
when stresses from welding should be reduced to avoid stress-corrosion-cracking
heat temperature should be conducted (e.g. ½ h at 900°C).
Highly ductile. As with 1.4541 only when sharp tools should
be used for machine cutting. The steels can be polished.
Field application: Nuclear Power plants, construction
of chemical equipment, textile and paper industries, fat,
soap, and nitric acid industries, food processing, dairy and
brewery works.

Corrosion and heat resistance: Excellent
Corrosion resistance. Can be operated in an atmosphere with
carbon dioxide content upto 900°C. Resistance to concentrated
nitric acid at 200°C and molten nitrates upto 420°C.
Continuous operation in air upto approx. 1150°C and with
temperature variation up to approx. 1000°C. Not recommended
- the use of the material in continuous operation between
550°C and 850°C because the material has a tendency
to aphase precipitation and is constantly brittle after cooling,
to room temperature.
Welding and mechanical properties: Arc welding techniques
are used on this material. Neither pre-heating nor heat treatment,
subsequent to welding are required. Perfect for hot and cold
working processes. Following hot or cold work heat treatment
is recommended (1150°C - 1100°C, cooling in water
or in air) Machine cutting can be performed providing high
quality tools are used and the correct cutting conditions
are selected. Hard metal tools are recommended.
Field application: In all fields where excellent scaling
resistance and simultaneous hot tensile strength are of advantage.
The high NI content results in sensitivities to furnace gases
with a sulphur contents, in particular in reducing atmospheres.
Particularly in : nuclear power plants, crude oil and petrochemistry,
furnace construction, heat exchanger , air preheaters, cement
kilns , brick kilns and glass works.

Corrosion and heat resistance : Highly
resistance to general corrosion and stress-corrosion-cracking.
The limit for use in carbon dioxide is around 500°C, as
from 650°C corrosion increases drastically. Inconel 600
should not be used in liquid sodium above 750°C because
higher temperatures above 550°C in a S-containing atmosphere.
Can be operated in water free of CI up to 590°C
Welding and mechanical properties : suitable for all known
welding techniques. Annealing should precede welding. Suitable
for brazing and soldering. Very high ductile. Inconel 600
is a high nickel content alloy thus exhibiting excellent mechanical
properties at higher temperature. The material is soft and
robust and facilitates machining-cutting providing it is not
machined in the annealed condition but in the rolled conditioned.
Field application : Standard material for the construction
pf PWR plants , nuclear power plants, furnace construction,
man-made fibre production, synthetic material, production
paper industries, food processing, steam boilers, column stills,
aircraft engines.
