When comparing the chemical composition of 321 SS and 304\/304L SS, it is clear that the chromium (Cr) and nickel (Ni) ranges of these alloys are very similar. The difference appears when the issue of carbide precipitation in the heat-affected zone (HAZ) is discussed or fatigue strength and temperature are considered.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cstrong\u003eCarbide precipitation\u003c\/strong\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe weld areas with temperatures 930°F 1470°F are often called the carbide precipitation zone in which Chromium (Cr) combines with Carbon (C) and precipitates chromium carbides at the grain boundaries significantly reducing corrosion resistance of steel in this zone. One of the ways to combat this phenomenon is to lower the carbon content in steel to decrease the carbide precipitation. 304L SS is an example of such steel; the \"L\" in 304L is for \"Lower carbon\" (.030% max vs. .080% max for 304 steel). An even more effective way to reduce carbide precipitation is through the addition of Titanium (Ti) to the alloy to stabilize it. The carbon is more attracted to the Titanium (Ti) and therefore it leaves the chromium alone. To be a true \"stabilized\" grade the 321 steel has to have Titanium (Ti) content at least 5 times than its Carbon (C) content. Reduced risk of corrosion in the HAZ is the main advantage of 321.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cstrong\u003eFatigue strength\u003c\/strong\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eIn dynamic applications, fatigue strength is also important to consider. And in this respect 321 SS has a slight advantage over 304 SS. Fatigue or endurance limits (strength in bending) of austenitic stainless steels in the annealed condition are about one-half the tensile strength.Typical tensile and endurance limits for these alloys (annealed) are presented in the table below:\u003c\/p\u003e\n\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eAlloy\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cstrong\u003eTypical Tensile\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cstrong\u003eTypical Endurance Limit\u003c\/strong\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e304L\u003c\/td\u003e\n\u003ctd\u003e68 ksi\u003c\/td\u003e\n\u003ctd\u003e34 ksi\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e304\u003c\/td\u003e\n\u003ctd\u003e70 ksi\u003c\/td\u003e\n\u003ctd\u003e35 ksi\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e321\u003c\/td\u003e\n\u003ctd\u003e76 ksi\u003c\/td\u003e\n\u003ctd\u003e38 ksi\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\n\u003cp\u003e\u003cstrong\u003eTemperature Factors\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eTemperature factors could be another factor to consider in some applications.
