347 Stainless Steel In Petroleum Refining

In the petroleum refining industry, a growing emphasis is being positioned on high-alloy, corrosion resistant stainless steels to cope with a wide variety of Tower uncooked crudes. Corrosives found in many refining processes embrace, however will not be restricted to: sulfur, naphthenic acid, polythionic acid, chlorides, carbon dioxide, ammonia, cyanides, and phenols. Stainless steel materials can be utilized in lots of petroleum refining functions, resembling fluid catalytic cracking units and polythionic acid service. In fluid catalytic cracking items, virgin and cracked gasoline oil fractions from crude distillation are processed to produce motor gasoline blending stocks and petrochemical feedstocks.

Varieties 304, 321, and 347 stainless steel are most commonly used in petroleum refining including fluid catalytic cracking units. They’re additionally utilized in refineries for high pressure heaters and heater tube supports. These austenitic grades of stainless steel have excellent excessive-temperature energy characteristics and are resistant to oxidation and sulfidation. Nevertheless, 304 stainless steel is susceptible to grain boundary chromium carbide precipitation “sensitization when heated in the range of 800°F to 1500°F. Consequently, the place “sensitization is to be averted, refineries desire to use stabilized grades, resembling sort 321 stainless steel which is stabilized with titanium or 347 stainless steel, which is stabilized with columbium.
