Parameter
Type 347 / 347H stainless steel is an austenitic grade of chromium steel, which contains columbium as a stabilizing element. Tantalum can also be added for achieving stabilization. This eliminates the carbide precipitation, as well as intergranular corrosion in steel pipes. Type 347 / 347H stainless steel Coiloffer higher creep and stress rupture properties than grade 304 and 304L. This makes them suitable for exposures to sensitization and intergranular corrosion. Moreover, the inclusion of columbium allows 347 Coil to have excellent corrosion resistance, even superior to that of 321 stainless steel coils. However, 347H steel is the higher carbon composition substitute of stainless steel coil grade 347. Therefore, 347H steel coils offer improved high temperature and creep properties.
With wide experience and expertise, Bozhong Group is one of the leading 347/347h stainless steel coil/wire/strip manufacturers and suppliers. We have hundreds of high-qualified workers at your service. Please rest assured to get the competitive price 347/347h stainless steel coil/wire/strip for sale with us.

Corrosion Resistance:
1, Offers similar resistance to general, overall corrosion as Alloy 304
2, Used for applications where alloys such as Alloy 304 are vulnerable to intergranualr corrosion
3, Generally used for heavy welded equipment which cannot be annealed and for equipment which is operated between 800 to 150°F (427 TO 816°C)
4, Alloy 347 is preferred over Alloy 321 for aqueous and other low temperature environments
5, Primarily used in high temperature environments where resistance to sensitization is necessary, in turn preventing intergranualr corrosion at lower levels
6, Susceptible to stress corrosion cracking
7, Exhibits oxidation resistance similar to all other 18-8 austenitic stainless steels
Weldability
1, Austenitic stainless steels are considered to be the most weldable out of all high alloy steels
2, Can be welded by all fusion and resistance welding processes
Heat Treatment
1, Annealing temperature range is 1800 to 2000°F
2, May be stress relief annealed within the carbide precipitation range of 800 to 1500°F without any danger of subsequent intergranualr corrosion
3, Cannot be hardened by heat treatment
