Hardening. Grade 347H stainless steel is unresponsive to heat treatment. The hardness and strength of the steel can be increased through cold working. Stainless steels are high-alloy steels which have high corrosion resistance than other steels owing to the presence of large amounts of chromium in the range of 4 to 30%.
1. Introduction. Three hundred and forty-seven austenitic stainless steel is one of the most common types of steel used in industries, especially in oil and gas industry, refinery and electric power stations because of its corrosion resistance to water environments and high temperatures [1], [2].This alloy has good resistance to …
Alloy 347 is a stabilized, austenitic, chromium steel containing columbium which allows for the elimination of carbide precipitation, and, consequently, intergranualr corrosion.
The most common of these stabilized grades are types 321 and 347. Type 321 contains a minimum of 5 × (C% + N%) titanium, and type 347 a minimum of 8 × C% niobium. Nitrogen must be considered when titanium is used as a stabilizer, not because the precipitation of chromium nitride is a problem in austenitic steels, but because titanium …
