347 / 347H Stainless Spring Steel Strip , Thin Stainless Steel Strips For Construction
| 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. |
