Austenite, any of the high temperatures. Featuring alloy this group its proximity to carbon and its magnetic and weldability low, and resistance to corrosion moderate, as the corrosion resistance of the alloy of this group is less than the alloy groups II and III, and that the tensile strength and hardness have to be high so they are used for the purposes that require tensile strength and hardness highs and corrosion resistance is relatively moderate.
Used in the manufacture of parts of valves and bearings such as alloy 440 is also used for the manufacture of alloy 420 surgical instruments.
Stainless steel Alfreta
This type contains a high proportion of chromium compared with other species, which lead to the stability of ferrite as it is non vulcanization. Among the most famous types of alloys of this group is the ingot 430, which is characterized by resistance to good corrosion in the air, for the same, they are widely used in industry decorations auto parts in the oxidation of ammonia plants in the household cutlery industry, such as dishes and pots as well as refrigerators, washing machines etc ..., and types 422 446 characterized resistance sulfur gas because of the high percentage of chromium.
The newly emerged another type for this group, a stainless steel high purity Alfreta which contains a very small proportion of carbon, nitrogen and most important advantage is the high mechanical properties of the weld area that are lacking in other alloys. The most important of the good features of the alloy of this group is its resistance to corrosion, especially in water containing chlorides Alajhadi.
Stainless steel austenitic
The alloy of this group are more kinds of stainless steel widely used because of its advantage of the mechanical properties and corrosion resistance competently and can be welded as it is non-magnetic and becomes hardened when rapid cooling to contain manganese, nickel and nitrogen.
Because of the availability of these properties which are used in cases where the circles are helping to corrosion in various industrial processes and construction purposes in the kitchen and in the pharmaceutical industry and in the purposes that require not get rust whatever degree is more alloy this group widely used and useful are the alloys 304 and 304L and 316 and 347 in addition to carpente 20.
