431 (1.4057) grade stainless steel contains both chromium and nickel in its components. Structurally, 431 (1.4057) grade stainless steel, which has its own special usage areas, can be increased to very high levels in terms of tensile strength when subjected to heat treatment after annealing. In the general literature, the 1.4057 quality code or 4057 quality code is commonly used in relation to 431 grade stainless steel.
In the production of stainless steel of this quality, heat treatment is applied as standard and delivered to users in this way. Stainless steel is a material with high thermal conductivity and suitable for polishing. It continues to maintain its surface structure at high temperatures and maintains its performance. Although its common name is 431, in some places it is known as 4057 and 1.4057, as well as its purely theoretical name X17CrNi16-2, which refers to its components. The strength of this product after heat treatment, for which there are many substitutes, is the reason why users prefer it.
Corrosion Resistance (* * * *) In terms of corrosion resistance, the performance of 431 (1.4057) grade stainless steel is very successful. 431 (1.4057) grade stainless steel, which shows corrosion resistance in accordance with many conditions in terms of corrosion resistance, has a higher corrosion resistance than 420 grade stainless steel, which is often seen as an equivalent. It is also observed to perform better than 420 in hardness and temperature resistance.
Mechanical Properties (* * * *) 431 (1.4057) grade stainless steel is supplied after heat treatment immediately after production in accordance with general standards. With this feature, the material coming from it with heat treatment is defined by the code of the breaking resistance obtained according to the heat treatment applied.
Malleability (* *) 431 (1.4057) grade stainless steel is generally suitable for forging due to its nickel content. However, since the carbon content is higher than the average, it is not very suitable for forging after heat treatment. Since forging steels with high carbon content after heat treatment may cause fractures and cracks, 431 (1.4057) grade stainless steel should not be forged.
Weldability (* * * *) 431 (1.4057) grade stainless steel is not recommended for welding due to its very high carbon content. If stainless steels with high carbon are exposed to the welding process, swelling due to carbide occurs in their tissues. However, 431 (1.4057) grade stainless steel can be welded when deemed necessary.
Machinability Feature (*) Since 431 (1.4057) grade stainless steel is offered for natural use in a heat treated state, the hardness level reached on its surface is at least 30-32 HRC levels. For this reason, it is a stainless steel material with a hard texture and high strength. Due to this situation, the performance of 431 (1.4057) grade stainless steel will be lower compared to other stainless steels in terms of machinability.
This stainless steel, which has high textural hardness and strength, can be used in the production of bolts and nuts. On the other hand, 431 (1.4057) grade stainless steel is also suitable for use in impeller shafts and pump shafts. Apart from these, the areas where 431 (1.4057) grade stainless steel is used include mixer rods, marine equipment and various laboratory equipment. In general, the most critical feature that distinguishes 431 (1.4057) grade stainless steel, which has lower levels than some metals in terms of all its parameters, is its readily heat treated and its strength in hardness. With all these features, 420 quality stainless steel can be evaluated if an equivalent to stainless steel of this quality is sought.
