One of the most widely used types of stainless steel product group, 319 quality stainless steel is developed from 304. A component of 316 quality stainless steel, which contains more nickel than 304, is molybdenum. Due to its molybdenum content and higher nickel content, its corrosion resistance is very high. It maintains its resistance performance for a long time even in environments with very high corrosion conditions (acid, sea water, etc.). Again, compared to 304 grade stainless steel, 316 grade has a very high tensile strength. This tensile strength, defined as “Ultimate Strength”, is provided by molybdenum. As a production, 316 quality stainless steel is produced in rod, hexagonal, lama or square shapes and in different thicknesses. Especially in environments where liquid chemicals are used intensively and hot water vapor is predominantly present, resistance to harsh corrosion conditions can be shown by using 316 quality stainless steel.
Corrosion Resistance (* * * * *)
Compared to 303, 304 and 304 L stainless steels, 316 grade stainless steel shows very high corrosion resistance. 316 Ti or duplex (1.4462) grade stainless steel is used for environments where 316, which is the most preferred steel grade in environments with high corrosion, will also be difficult.
Mechanical Properties (* * *)
316 grade stainless steel, which has a similar mechanical structure to 304 grade, can show the same performance under similar mechanical conditions. If production by heat treatment is in question and mechanical properties are important, grade 431, duplex (1.4462) grade or 630 grade stainless steel can be used to obtain a higher strength performance.
Malleability (* * *)
Just like 304 and 304 L grade stainless steels, 316 has very good malleability and formability.
Weldability Feature (* * * * * * *)
316, which exhibits the same properties as 304, which has a similar carbon ratio in terms of weldability level, if it is to be used for an environment where welding is high and the risk of corrosion after welding should be prevented, low carbon 316 L or 316 Ti grade stainless steels can be preferred instead.
Machinability (*)
Although 316 grade stainless steel shows a good performance in terms of machining, if corrosion resistance is not important, better machinability performance can be obtained with 303 or 430 F grade stainless steels.
316 grade stainless steel is a steel material developed from 304, so its quality is high. Since it has high corrosion resistance, it can be preferred in many environments compared to 304. In this sense, the use of 316 grade stainless steel is generally preferred in environments where corrosive and oxidizing chemical materials are used, in liquid tanks where corrosive liquids will be protected, in steam boilers, in the chemical and petrochemical field, in the paint industry, in the food industry and in mining. According to EN standards, 316 stainless steel, defined by the code 1.4401, is also known by the code X5CrNiMo17-12-2. Internationally, grade 316 stainless steel is as widely preferred as grade 304 and has the potential for a wide range of uses. They are in the austenitic stainless steel class and perform very well in both welding and formability.

Summary of Quality Attributes
Grade 316 stainless steel is coded as grade 1.4401 stainless in EN standards.
316 grade stainless steel is also coded as X5CrNiMo17-12-2 in EN standards.
316 and 316L grades of stainless steel are the most preferred stainless steel grades in the world along with 304 grades of stainless steel.
This stainless quality is in the austenitic stainless group.
The weldability and formability of this stainless steel quality material is good.
Stainless steels of this quality are not magnetized and have good corrosion resistance.
316 quality stainless steel shows a better corrosion resistance than 304 quality.
If a high corrosion resistance is required in steel, 316 grade stainless steel has more resistance than 304. 316 quality stainless steel is among the second most important members of a family similar to 304 quality. When we look at what is taken from the manufacturers as consumption, it is consumed at a rate of 30%.
316 quality steel type has serious resistance in extremely corrosive environments such as building exteriors. Especially in buildings near the sea, marine vehicles, bridges and beams in highly oxidized environments, 316 quality steel is suitable for use. Since it is easy to clean, it can be used in food production facilities, as well as in environments where chemical paints and organic substances are used because of its resistance.
Grade 304 is resistant to oxidation when exposed to continuous application at 800-900°C with heat resistance. 316 L shows better corrosion resistance than 316 H in environments with carbide precipitates. In high heat environments, Grade 316 and Grade 316 H show higher corrosion resistance. Except for gas fusion welds, Grade 304 can be used in all kinds of welds with its weldability feature.
Under normal conditions, after welding, it may not be subjected to light treatment. However, the color differences and impact caused by welding that may occur on the surface should be removed chemically and mechanically. Otherwise, corrosion resistance will be low. It can be used especially in yacht accessories, fasteners and exterior facades of the above-mentioned buildings, bridge beams, chemical and petrochemical industry, food plants, boilers of industrial kitchens, heat exchangers and water tank type products. 316 grade steels are available in the market in forms such as sheet, plate, bar, strip, plate, profile and pipe.
