All our UNS S21800,Alloy 218 forged material must give the material a required purity necessary for the application in following melting methods
one is triple melted material,VIM+ESR+VAR., the another one is double melted material,VIM+VAR.
UNS S21800,Alloy 218 is high Silicon, high Manganese, Nitrogen strengthened austenitic stainless alloy. UNS S21800,Alloy 218 is an all purpose metal that was originally designed as a temperature alloy and therefore performs well at high temperature around 1800ºF. The additions of silicon and manganese assist to inhibit wear, galling and fretting even in the annealed condition. Through cold working UNS S21800,Alloy 218, it is possible to attain higher strengths, however it does not enhance the anti-galling properties. The oxidation resistance of UNS S21800,Alloy 218 is similar to Alloy 309 and far superior to Alloy 304.
UNS S21800,Alloy 218 is used in the Aerospace , Food and Drug, Oil Field, Petrochemical, Surgical and Chemical Processing Industries.
The forging ratio of all our UNS S21800,Alloy 218 forged bars is minimum 3:1
Microstructure test of UNS S21800,Alloy 218 forged round bars
The microstructure must be uniform and free from extensive segregation and other inhomogeneity. Determination of grain size has to be performed according to EN ISO 643. Grain size checking of sheets shall be performed to the top and the bottom of a forged bars table
for each melt, thickness and heat treatment lot. Sheets shall achieve a mean grain size of 2-6. Grain size checking of bars shall be performed for each melt heat treatment lot. Bars shall achieve a grain size of 5 or coarse
