430 (1.4016) stainless steel, which is included in the ferretic group among stainless steels, is a stainless steel material with low carbon and chromium. 430 (1.4016) grade stainless steels, which have limited weldability due to their component properties, do not contain nickel and molybdenum among their components. 430 (1.4016) quality stainless steel, which is magnetizable due to the absence of nickel in its content, provides an advantage in price since it is molybdenum-free. 430 (1.4016) quality stainless steel creates a pleasant surface appearance in the product and environment where it is generally used. Stainless steels of this quality are not subjected to heat treatment and are generally mixed with 4301. However, 430 grade stainless steel has very big differences compared to 431 grade stainless steel.
Corrosion Resistance (* * *)
Although the corrosion resistance of stainless steel of this quality is not very high, it is often used in manufacturing for decoration purposes. It is recommended to use this material, which has a price advantage, only in environments with low corrosion conditions and it should not be forgotten that it may corrode in humid environment.
Mechanical Properties (* * * *)
Although 430 grade stainless steel, which performs above average in terms of mechanics, is not recommended when excessive strength is required, it can be used as a result of its cost advantage in cases where mechanical conditions are required where corrosion conditions may be weak.
Malleability (*)
The forgeability of stainless steel of this grade is very low and is not recommended because the material is frangible during the forging process.
Weldability Characteristic (*)
Since stainless steel of this grade is not suitable for welding, welding is not recommended.
Machinability Feature (* * *)
Instead of 430 grade stainless steel, which offers an average level of machinability, 430F grade stainless steel containing sulfur in its component can be used if the processing will be intensive.
The usage areas of stainless steel of this quality have recently become widespread and are utilized in a wide range both in Turkey and in the world. 430 grade stainless steel, which is frequently preferred especially for decorative purposes and in the automotive industry, is a stainless steel quality suitable for use in household appliances, kitchenware, washing machines and areas where a shiny surface is required. 430 quality stainless steel is widely used in white goods.

Mechanical Properties at Room Temperature
430 stainless steel is among the ferretic stainless steels. 430 or 1.4016 stainless steel with its code in EN standards is a type of stainless steel whose international use is developing rapidly. 430 quality stainless is also coded as X6Cr17 in EN standards. 430 grade stainless steel is generally known for its suitability for polishing (polishing) and shaping. 430 stainless steel material is magnetic and can be magnetized. 430 grade stainless steel has poor corrosion resistance.
Stainless Steel 430 This product is in the ferritic group and is the best among stainless steels. 430 The most important issue to be considered in stainless steel is that the light process is done correctly and successfully. As a result of the processes carried out in this way, it provides lifetime use and its corrosion resistance increases incredibly. Its resistance is especially valid in chloride-free conditions.
It is also resistant to aqueous, weak acidity, weak organic acids and detergent corrosion. It is heat resistant up to 800-850 °C and continuously up to 850 °C. The same resistance is also seen against scale formation. It shows the same resistance to sulfur-containing gases, such as gases from coal and oil-fired furnaces. While machining properties are similar to unalloyed steels, 430 grade steel also shows a tendency to plaster due to its soft ferritic microstructure.
The welding feature is at medium level. However, it should be annealed after welding. Similar to other stainless steels, gas melting should not be used, and it should be noted that all other welding techniques can be applied. Sheets thicker than 3mm should be annealed between 150-200 C. For some special applications, expert support should be taken into consideration.
In terms of usage areas, 430 quality stainless steel is used in automotive, body parts, bumpers, kitchen utensils, kitchen industry and pharmaceutical industry. You can also get great results in interior design. It is available in the market in coil, bar, sheet, plate and strip forms.
