Summary of Quality Characteristics
It is numbered 1.4541 quality stainless according to 321 stainless EN standard.
321 grade stainless is also called X6CrNiTi18-10 according to EN standard.
This quality is of the stainless steel grade.
Stainless steel of this quality does not attract magnets and has a high corrosion resistance.
321 grade stainless material can work at temperatures up to 800 degrees.
The internal structure of the 304 quality is similar to the quality of this stainless steel 304 is separated from the most important point is the titanium available. Titanium adds resistance to both stainless steel and temperature
321 stainless steel is not suitable for extremely high temperatures and it will be more accurate to use stainless steel grades such as 310 or 310s at very high temperatures.
321 Quality Stainless Steel Alternatives
In which cases can this quality be preferred instead of 321 quality stainless?
Stainless steel grades 321 and 316Ti are similar to each other. X6CrNiTi18-10 shows similarities to 1.4541 quality (ie, 321) and X6CrMoTi17-12-2 1.4571 (i.e. 316Ti) chemical exposures. 316Ti material is more suitable for places where the corrosion resistance is higher. The most important content difference between 316Ti and 321 is the element of molybdenum element ~ 2-2.5% of the quality material of 316Ti (1.4571).This element, which is indicated by Mo, increases the cost of the material but increases the resistance of the stainless steel.
310 / 310s
The 310 stainless material, called 1.4845, can be operated even at about 1100 degrees. It is known that the temperature at which 321 quality materials work at maximum is 800 degrees and it is not recommended to use 321 quality materials for temperatures above 800 degrees. If 321 is used above 800 degrees it will melt very quickly and the structure of the material will deteriorate. Even if it is more expensive in terms of cost, 310 quality is much more suitable for high temperatures than 321 stainless.
