Though the base chemical composition of both 304, as well as grade 321H, remain the same, there are some modifications that distinguish them both. First, the letter H added to grade 321 indicates that the 321H stainless steel round bar has much higher carbon content in comparison to both grade 304 & alloy 321. The increase in carbon is to improve the resistance of the alloy to heat. The second important change in the chemistry is the inclusion of titanium in the alloy of ASTM A479 UNS S32109 hex bar. Titanium is responsible for two changes in the alloy. 1.

Titanium acts as a stabilizing agent in the alloy and it improves the performance of the 321H stainless steel rods at elevated temperatures. And 2. High carbon alloys like these are susceptible to sensitization at the grain boundary precipitates making the JIS SUS 321H black bar a liability as it is susceptible to failure and therefore cracking.  In such an alloy there is a possibility of the extra carbon forming carbide precipitates and weakening the weld area. However, because of the addition of titanium in astm a276 type 321H flat bar, the carbon gets attached to the free titanium forming a much stable compound referred to as titanium carbide.

The presence of this compound on the weld seam of ss 321H bright bar is relatively harmless. Hence, the high content of carbon along with the inclusion of titanium in the alloy of AISI 321H threaded bar brings up the tolerance of the material towards heat. Not forgetting the excellent performance of DIN 1.4878 square bar in cryogenic temperatures due to its high impact resistance properties as well.
