Considering that 304 grade stainless steel is the center quality stainless steel, it can be considered that other steel grades are obtained by adding components to this type of steel or by removing or subtracting components. Thus, the properties of steel products depending on their quality can be compared.
In this sense, 316 quality stainless steel is obtained by adding molybdenum to the component of 304 quality stainless steel and increasing the nickel ratio. With these properties, it exhibits higher corrosion resistance and higher tensile strength compared to 304 grade stainless steel. 316 grade stainless steel, which is similar to 304 in terms of mechanical and machinability, also has two different subtypes.
One of these types is 316 L, which has “Low Carbon” properties and thanks to its low carbon content, it becomes a prominent material in terms of weldability. Another 316 quality type is 316 Ti.
When titanium is added to the components of 316 grade stainless steel, the steel material obtained is defined as 316 Ti. This material becomes more resistant to temperature conditions with titanium content. If there are situations where the material will remain between 550-800 degrees for a long time, 316 Ti should be preferred instead of 316 model non-corrosive steels.
This version of 316, which is preferred in environments where corrosion resistance is important, also shows resistance to extremely hot conditions, generally contains a low percentage of titanium. The rate we are talking about is generally about 0.5%. The usage areas of 316 Ti, which has better properties than 304 and 316 quality stainless steels with its titanium feature, are also more focused than these two steel types.
DEFINED PROPERTIES OF 316 Ti QUALITY STEEL:
Corrosion Resistance (* * * * *)
316 Ti grade steel shows a very good corrosion resistance performance as it is developed from 316 stainless steel grade. However, if the corrosion conditions in the working environment are high, then (1.4462) stainless steel grade can also be used.
Mechanical Properties (* * *)
The mechanical properties of 316 Ti grade stainless steel are generally the same as 304, 304 L and 316, which are central stainless steels. In environments where mechanical conditions are important and higher mechanical strength is desired, 431, (1.4462) or 630 stainless steel grades are preferred instead of 316 Ti.
Malleability (*)
In terms of forgeability, 316 Ti models offer a lower level of performance. Because the structure of the material has reached a harder form due to the titanium element it contains. Therefore, breakage or cracking may occur during forging. In this respect, 304 or 316 grade stainless steel is preferred in areas where heat conditions are insignificant and malleability is more necessary.
Weldability Feature (* * * * *)
Because it contains titanium, it is generally thought that 316 Ti grade stainless steel will have poor welding performance, but this is a misconception. 316 Ti, which has a very good welding ability, can be replaced by 316 L if there is a work environment with high welding requirements.
Machinability (* * *)
Increasing the machining capability of 316 Ti grade stainless steel depends on good annealing by seeing very good and high quality applications during the production process. If it is appropriate to use stainless steel with low corrosion resistance, 303 or 430 F model products that are practical to process can be used.
316 Ti stainless steel can be used as a substitute in all environments where standard 316 model steel can be used. In addition, 316 Ti is more advantageous if corrosion resistance is desired with higher temperature conditions.

Quality Specifications
The 316Ti model is coded 1.4571 in EN standards.
316Ti is also coded as X6CrNiMo17-12-2 in EN standards.
316Ti is widely used in a wide range of applications. Its practicality is lower and its cost is higher compared to 316 and 316L stainless steel.
It is in the austenitic stainless group.
Although its quality is favorable for weldability, it is not prone to forging.
Products are non-magnetized and corrosion resistance is quite high.
316Ti stainless shows high resistance in environments with high friction due to its titanium content.
The corrosion resistance of the 316Ti model is higher than 304 stainless steel. This product is produced with the addition of titanium to 316 stainless steel. It has high temperature and oxidation resistance. It has the power to withstand temperatures of 600-700°C. In environments with abnormal conditions, it shows more corrosion resistance than 304 type stainless steel.
If the material is used in a hot environment for a long time, 316TI may be preferred. You can get successful results with 316TI in abrasion liquid containers, boiler production, steam boilers, compressor parts, pumps, paint production facilities, mining, chemical and petrochemical production facilities.
3016TI, which is included in the austenitic group, is a product that is widely used. Stainless steels, which are easy to clean and hygienic, are therefore used in many household appliances. It is preferred because it is an excellent environmentally friendly product. The recycling rate of this product is determined as 100%.
In addition to showing durability for many years, it is also successful and respectful to the environment. Due to its 316TI corrosion resistance, which can be used for a lifetime, it is widely used and preferred in the food and food production sectors.
Apart from this, it is also among the indispensable raw materials of the automotive industry. It draws attention as a suitable material for obtaining special results especially for exhaust systems.
