TISCO top quality 347/347H stainless steel hot rolled plate, 347/347H cold rolled stainless steel sheet

Short Description:

347 (S34700) is a stabilized, austenitic, chromium steel containing columbium which allows for the elimination of carbide precipitation, and, consequently, intergranualr corrosion. Alloy 347 is stabilized by the additions of chromium and tantalum and offers higher creep and stress rupture properties than alloy 304 and 304L which may also be used for exposures where sensitization and intergranualr corrosion are of concern. The addition of columbium also allows 347 to have excellent corrosion resistance, even superior to that of alloy 321.  347H is the higher carbon composition form of 347 and demonstrates improved high temperature and creep properties.

347 stainless steel plate is also advantageous for high temperature service because of its good mechanical properties. 347 stainless steel plate offers higher creep and stress rupture properties than 304 and, particularly, 304L, which might also be considered for exposures where sensitization and intergranular corrosion are concerns.

Hot Working

Alloy 347 stainless steel plate can be easily welded and processed by standard shop fabrication practices.

Cold Forming

The alloy is quite ductile and forms easily.

Hot Forming

The high sulfur content of Alloy 303 also has a detrimental impact on hot workability. If hot forming is required, once again, 304 should be considered as an alternate selection.

Machining

The cold work hardening rate of 347 stainless steel plate makes it less machinable than 410 stainless steel, but similar to 304.
