ASTM 321 stainless steel and 347 stainless steel,ASTM 321

ASTM 321 stainless steel and 347 stainless steel are the basic austenitic 18/8 steel (Grade 304) stabilised by ium (321) or Niobium (347) additions. These grades are used because they are not sensitive to intergranular corrosion after heating within the carbide precipitation range of 425 850°C.

AISI 316 Stainless Steel vs. AISI 321 Stainless Steel

Both AISI 316 stainless steel and AISI 321 stainless steel are iron alloys. They have a very high 96% of their average alloy composition in common. There are 33 material properties with values for both materials. Properties with values for just one material (3, in this case) are not shown.

The advantages of using 321 SS vs. 304/304L SS Penflex

To be a true “stabilized” grade the 321 steel has to have ium (Ti) content at least 5 times than its Carbon (C) content. Reduced risk of corrosion in the HAZ is the main advantage of 321. Fatigue strength. In dynamic applications, fatigue strength is also important to consider. And in this respect 321 SS has a slight advantage over 304 SS.

321 Stainless Steel Technical Data Sheet metal shims

Type 321 is a stabilized stainless steel which offers as its main advantage an excellent resistance to intergranular corrosion following exposure to temperatures in the chromium carbide precipitation range from 800 to 1500° F (427 to 816° C). Type 321 is stabilized against chromium carbide formation by the addition of titanium.

Difference between ASTM 310 stainless steel and 310S

Difference between ASTM 310 stainless steel and 310S stainless steel. ASTM 310S stainless steel has good oxidation resistance, corrosion resistance, because a higher percentage of chromium and nickel, so has much better creep strength at high temperature continuous operation, with good heat resistance.
