316 (1.4401)

316 stainless steel is a stainless steel quality obtained by adding molybdenum and more nickel into 304 quality stainless steel. Thanks to this content, the corrosion resistance of 316 grade stainless steels is very good even in harsh conditions (seawater, acidic liquids, etc.). Moreover, the ultimate strength of 316 grade stainless steel is much higher than that of 304 grade stainless steel. 316 quality stainless steel materials in our company are available in various thicknesses in rod, hexagonal, lama and square shapes and in the following material list. 316 grade stainless steel is also called stainless steel 1.4401 grade.

Grading Quality Characteristics

General features Point Explanation
Corrosion Resistance: The corrosion resistance of this material is quite good. In the more stringent conditions, 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) may be preferred.
Vulnerability to be beaten: This quality stainless steel has a good forging tendency.
Weldability: The weldability of this quality stainless is good. 316L or 316Ti stainless steel should be preferred in environments with more resources.
Machinability of: In environments where corrosion resistance is insignificant, stainless steel products of grade 303 or 430F may be preferred.
NOTE: Scores are indicated on 5 and are intended to facilitate understanding of the nature of the material. It is only intended to make comparisons between qualities without relying on any value.


Usage areas 

316 quality stainless steel material due to the high quality of the wide range of uses. For example, it is recommended to use stainless steel materials in tanks and storage tanks of corrosive liquids, chemical and petrochemical industry, steam boilers, paint industry, food plants and mining in grades 316 (1.4401).

Summary of Quality Characteristics

316 stainless is numbered as 1.4401 quality stainless according to EN standard.

316 grade stainless is also called X5CrNiMo17-12-2 according to EN standard.

316 and 316L stainless steel quality stainless steel 304 quality stainless with the most widely used stainless steel grades.

This quality is of the stainless steel grade.

These stainless steel grade materials can be well formed and welded well.

Stainless steel of this quality does not attract magnets and has a high corrosion resistance.

Corrosion resistance of 316 grade stainless steel is better than 304 grade stainless steel.
