Today, in the world of industry and the production of precise parts, speed and quality are the first words. One of the vital materials that has been able to create a great transformation in the industries of component manufacturing, automobile manufacturing and machining are well-turned steels, which are also known as automatic iron in the Iranian market. If you are a manufacturer looking to increase the efficiency of your CNC and lathe machines, choosing the right raw materials is critical. This article is written with the aim of providing you complete guidance for purchasing high-quality automatic iron and steel in Tehran and examines all the technical, price and commercial aspects of this product. Also, in this direction, we will introduce Kamil Foulad Industrial Group as one of the best and most reliable suppliers of these steel sections.
What is automatic iron or polished steel?
Before going to the tips of buying automatic iron, we should know the nature of this alloy. Free Cutting Steel, which is called automatic steel in market and workshop terminology, is a group of steels designed for high-speed machining.
The distinctive feature of these steels is the rapid chip breaking (chip breaking) during turning. This feature causes the shavings to separate into small and powdery pieces and not wrap around the workpiece or tool. This issue is considered a vital advantage in lathe and automatic series machines where the production speed is very high. The reason why it is named "automatic" is the ability to use it in fully automatic machines without the need for frequent stops to clean the shavings.
Constituent elements of well-cut steel
The secret of good cutting of these steels lies in their alloy elements. If you intend to buy quality automatic iron and well-cut steel in Tehran, you should know what elements determine its quality:
- Sulfur: The most important element in these steels is sulfur. Sulfur combines with manganese to form manganese sulfide (MnS). These compounds make the chips brittle and create internal lubrication properties. Lead: In some grades, which are called "leaded", lead element is added. Lead acts as an excellent lubricant and greatly reduces the friction between the tool and the part, which leads to an increase in the life of the tool. Phosphorus: Phosphorus also helps to improve the quality of the final surface, although its amount should be controlled.
All kinds of automatic iron grades in Tehran market
When visiting Tehran iron market (such as Shadabad) or contacting Kamil Foulad Industrial Group, you will encounter different grades. Knowing these grades is essential for a successful purchase:
1. Steel 1.0715 (11SMn30)
This grade is the most standard and widely used type of lead-free fine-cut steel. If your part does not need special heat treatment and only the cutting speed is important to you, this option is the most economical choice. This steel has a high sulfur content and is excellent for producing screws, nuts and common fittings.
2. Steel 1.0718 (11SMnPb30) – leaded automatic iron
This grade is the most popular option for precision industries. The presence of lead (Pb) along with sulfur maximizes machinability. If you are looking for automated iron with the highest production speed, the 1.0718 grade is the best option. The final surface of the parts produced with this steel will be very polished and shiny. Kamil Foulad Industrial Group has special expertise in supplying this grade with detailed analysis.
3. Steel 1.0736 and 1.0737
These grades, in addition to being well cut, have the ability of heat treatment and cementation (surface hardening) to some extent. If your piece needs to be hardened after turning, you should go for these grades.
The advantages of using well-cut steel in production
Why are big industries looking for purchasing automatic iron and high-quality steel in Tehran? The answer lies in cost savings:
- Increased production speed: Machines can work at higher revolutions and advances.
- Increased tool life: Depreciation of diamonds and cutting tools is reduced by 40%.
- Excellent surface quality: In many cases, the need for secondary work and grinding is eliminated.
- Reduced energy consumption: The force required to cut this Steels are less than normal steels.
- High dimensional accuracy: Due to less pressure on the tool, parts are produced with more accurate tolerance.
Guide to buying automatic iron in Tehran
Tehran, as the country's industrial hub, is the main iron distribution center. But it is not easy to find original and high-quality material in this crowded market. To buy quality automatic iron and high-quality steel in Tehran, you should pay attention to the following points:
1. Quality of surface and size (accuracy of tension)
Automatic iron is usually supplied in the form of trans rods (cold drawn). Its surface should be completely smooth, without scratches and polished. Dimensional accuracy (tolerance h9 or h11) is also very important so that it does not slip in the collet of lathes. Kamil Foulad Industrial Group provides you with accurate transformer loads, making you feel at ease about the size.
2. Material analysis test
Unfortunately, in the market, they sometimes sell regular irons instead of automatic ones. The only way to be sure is to take a sample and send it to a metallurgical laboratory. Reputable sellers such as Kamil Foulad Industrial Group always provide the customer with a factory certificate or analysis guarantee.
3. Origin of production (brand)
The polished steels available in the Iranian market are usually imported (Türkiye, Germany, Italy) or special domestic products (Yazd, etc.). Turkish and European brands usually have more uniform quality. When inquiring about the price, be sure to ask the country of manufacture.
Factors affecting the price of automatic iron and fine-cut steel
The price of this product is a function of several variables that buyers should be aware of:
- Currency price: Since most of these steels or their raw materials are imported, dollar fluctuations directly affect the price of buying auto iron.
- Global price of lead and scrap: The change in the global price of alloy elements such as lead changes the final price.
- Type of section: Price of round, hexagonal and Quadrilaterals are different from each other. Usually, six-ply sections have a higher price due to the complexity of production.
- The cost of stretching and polishing: The quality of the surface (single polishing or double polishing) affects the price.
To know the current and accurate price, it is suggested to contact the sales experts of Kamil Foulad Industrial Group to get the best competitive rate in the Tehran market.

The difference between an automatic iron and a normal iron (ST37)
Many novice buyers may not know the difference between the two. Ordinary iron (ST37) has excellent welding ability, but it is "tough" in turning; That is, its chips are stretched, welded on the tool and the surface of the piece becomes rough. But the automatic iron is exactly the opposite; It does not weld well (cracks due to high sulfur) but instead has excellent machinability. If your part is going to be welded, you shouldn't go for buying an automatic iron, but if it is going to be CNC machined, an automatic iron is the only logical choice.
How to recognize quality during cargo delivery
When you receive the automatic iron load, pay attention to these points:
- Visual inspection: Look at the ends of the branches. Granulation structure should be uniform. The outer surface should not have deep rust or crust.
- Shear test: The easiest way is to shave a small piece from the end of a branch. The shavings should be powdered and the bottom surface should be shiny like a mirror.
- Packaging: Imported quality goods are usually neatly packed, strapped and have a heat number plate. Kamil Foulad Industrial Group delivers loads with basic packaging so that they are not damaged during transportation.
The future of the polished steel market in Iran
With the advancement of industries and the arrival of more advanced CNC machines in the country, the need for quality materials is increasing day by day.
