Stainless Round Iron
Stainless irons are hard steel coatings whose usage areas are increasing rapidly and they have high resistance to rust. Stainless irons are among the most preferred stainless steel materials. Stainless irons It is obtained by processing or shaping stainless bar tools. Stainless steel irons are produced in the form of long strips and rolling or extrusion features are used during production. The most important factor in choosing these stainless irons is that they are robust and can be used for a long time. Because of these features, they are preferred in many branches to provide structural support.
In metallurgy, Stainless steel is defined as an iron-carbon alloy containing a minimum of 10.5% chromium element. Chromium is an element that protects steel materials against corrosion. Stainless steel iron, on the other hand, is formed by melting and shaping the stainless steel. Stainless steel iron is the most used pipe fitting among the stainless fitting materials. The production of Stainless steel iron, which has many uses, consists of a long and varied process. They are produced by using rolling and extrusion properties in the formation of stainless irons. This situation helps Stainless steel irons gain diversity. In addition, because they have a bright design, they not only strengthen the places they are used, but also provide harmony by creating a beautiful image. Stainless steel irons attract the attention of customers with their robustness against corrosion and aesthetically pleasing appearance. In addition to these, Stainless steel is preferred by most companies due to its durability and longevity.
Usage areas
Stainless steel irons have many uses today. These products, which are selected in various departments, gain the happiness of the buyers by maintaining their structure even in all kinds of temperatures and working environments where pressure values are different. If it is necessary to list some usage areas of stainless steel iron;
In the kitchen section: The Stainless steel irons used in the kitchen sections are mostly used in counter and shelf formations. It is possible to use the stainless steel irons in use safely in the kitchen sections due to the fact that they are strong.
Automotive part: Stainless steel irons used in automotive parts are mostly used in vehicle construction. The irons used in vehicle parts are widely used in the automotive sector, as they are extremely durable and formable.
In the construction section: The construction sector, which has the most usage among these usage areas, ensures that the construction foundations are formed in a durable and active manner.
In the weapon industry: They are used as a weapon part in defense and weapon systems.

Properties of Stainless Steel Irons
- cold rolling
- cold forming
- Rounding the fillet specifications
- cooling platform
It varies depending on the heat treatment in terms of including agitation and tempering and is suitable for the Stainless steel environments
304 quality stainless rods are among the most used products. Kitchen tools such as forks, knives and spoons are produced by pressing these sticks into various shapes.
The corrosion resistance of 316 quality stainless bars is higher than 304 quality bars. It is preferred in boat shafts, corrosion resistant shafts and areas where elasticity is required. In addition, the corrosion resistance of 316TI stainless bars produced by adding titanium to the alloy is even higher.
420 / 430F stainless bars are used in applications that require surface gloss. These products, which can be quite bright after polishing, are frequently encountered in decorative applications.

304 (1.4301) Quality Stainless Steel
|
Corrosion Resistance:
|
This quality, which is quite sufficient for daily use and standard productions, is not preferred because it will rust in more corrosive environments. In more demanding conditions, 316, 316L, 316Ti or duplex (1.4462) grade stainless steel should be preferred instead of 304 grade stainless steel.
|
|
Mechanical Properties:
|
This stainless steel quality, which is often sufficient in terms of mechanical strength, is not preferred where high yield and rupture strength is required. When the mechanical properties come to the fore, considering the material structure,

|
Tendency to Forge:
|
This quality material has a standard malleability. It should not be preferred in places where metal forging is extremely intense.
|
|
Weldability:
|
Plain 304 quality stainless steel is an ideal material for places where there is no excessive welding. In places where the weld is more intense, 304L quality material with lower carbon (L=low carbon) should be preferred to prevent swelling.
|
|
Machinability:
|
This material, which is not bad in terms of machinability, is not preferred in places where processing is intense. 304 quality stainless steel is less preferred, especially in lathes and machining centers, as it wraps chips. In places where this type of process is intense, 303 quality stainless steel, which is the automatic version of 304, should be preferred.

|
Stainless steels of this quality do not attract magnets and have a high corrosion resistance.
|
The corrosion resistance of 316 grade stainless steel is better than 304 grade stainless steel.
|
General features
|
Explanation
|
|
Corrosion Resistance:
|
The corrosion resistance of this material is quite good. In harsher environments, 316Ti or duplex (1.4462) quality material should be preferred.
|
|
Mechanical Properties:
|
316 quality material shows mechanical properties similar to 304 quality material. For higher strength, 431, duplex (1.4462) or 630 (1.4542 PH17.4) can be preferred.
|
|
Tendency to Forge:
|
This grade of stainless steel has a good malleability tendency.
|
|
Weldability:
|
Weldability of this quality stainless is good. In environments with more welding, 316L or 316Ti quality stainless should be preferred.
|

In environments where corrosion resistance is insignificant, 303 or 430F quality stainless steel products may be preferred.
|
|
420 (1.4021 – 1.4028 – 1.4034) Stainless Round Iron quality
|
General features
|
Explanation
|
|
Corrosion Resistance:
|
This material, which has an average corrosion resistance, can rust in very harsh conditions. It is recommended to use 304 stainless steel in harsh environments and 316L stainless steel in acidic environments.
|
|
Mechanical Properties:
|
This material, whose mechanical properties are average in annealed form, has a very strong mechanical structure after heat treatment. Those who do not want to deal with heat treatment and those who want a strong mechanical property can choose 431 quality or 630 quality stainless steel material.
|
|
Tendency to Forge:
|
Especially in places where a hard surface such as a knife is required, 420 quality is shaped by forging and then it is subjected to heat treatment to ensure that the surface has a hard structure. This material becomes more brittle after heat treatment and it is not recommended to be forged after heat treatment.
|
|
Weldability:
|
This material, which has an average weldability feature, can be used even in an environment with intensive welding. The most important point during the welding of this material is what kind of material the other surface to be welded is. For example, when 420 and 304 quality stainless will be welded together, it is necessary to be more careful and attentive.
|
|
Machinability:
|
Despite the high carbon content it contains, 420 quality stainless steel materials in the annealed state have a very good machinability. However, the ease of machinability may decrease somewhat after heat treatment. The shavings of 420 quality material in the annealed state break very easily, and thus, a problem such as chip wrapping is minimized during machining.
