SPECIFICATION OF 321 STAINLESS STEEL BAR
Type 321 stainless steel (UNS S32100) is a stabilized austenitic stainless steel similar to Type 304 but with a titanium addition of at least five times the carbon content. This titanium addition reduces or prevents carbide precipitation during welding and in 800 - 1500ºF (427 - 816ºC) service. It also improves the elevated temperature properties of the alloy.
Yieh United Co. has the stainless steel bar products you need positioned in large depots to meet your demand. Yieh United Co. carries processed bars not only in different types, but also in various grades includes special free-machining grades, food industry-approved grades and materials includes low-sulfur material and dual-certified material.
The normal stock of stainless bar is around 20,000 tons, which ensure the delivery time and flexible choice for our customers.
