Skytech Metal is a known manufacturer, distributor and trader of SS 347 / 347H Hex Bars, which has about the same general corrosion resistance as SS 302 Hex Bars. Our Stainless Steel 347 Hex Bars is columbium stabilized austenitic stainless steel plate by means of good general corrosion resistance and somewhat better resistance in strong oxidizing conditions than Stainless Steel 321 Hex Bars. Meanwhile, these Stainless Steel 347H Hex Bars is stabilized in contradiction of chromium carbide formation by the addition of columbium and tantalum. It has slightly improved corrosion resistance over our SS 347 Hex Bars in strongly oxidizing environments. These SS 347H Hex Bars are stabilized stainless steels which offer as their main advantage an excellent resistance to inter - granular corrosion following exposure to temperatures in the chromium carbide precipitation range from 800°F to 1500°F (427°C to 816°C). Our Alloy 347 Hex Bars is a stabilized, austenitic, chromium steel containing columbium which allows for the elimination of carbide precipitation, and, consequently, inter-granular corrosion.
These Alloy 347H Hex Barsis often used in high temperature gaskets and expansion joints, aircraft collector rings, exhaust manifolds, rocket engine parts, chemical production parts, and so on. Our 347 Stainless Steel Hex Bars alloyed with columbium - tantalum (referred to as niobium) allows good mechanical properties at high temperatures. These 347H Stainless Steel Hex Bars is used for heavy welded equipment when annealing is not possible.
