321 stainless steel grade is a really common grade which preferred for heat resistant applications. This grade is written as 1.4541 or X6CrNiTi18-10 according to EN norm and it is written as UNS S32100 according to UNS norm. 1.4541 stainless steel is similar to mix of 304 and 316Ti grades and we can think 321 grade as the mixture of these two different grades. This grade has a good corrosion resistance and at temperatures like 600-700 degree, this grade has still a good heat and corrosion resistance. 321 stainless is widely used in Germany and Russia. If this grade is not enough because of its heat resistance, then 310 / 310s grades can be choosen for higher temperatures. The ingridient of 321 grade is similar to 304 stainless steel grade so 321 grade can be considered as the titanium added version of 304 grade. In Birçelik warehouse, you can find 321 grade stainless steel in round bar shape.
