Equipment for use in corrosive environments and methods for forming thereof

A method for forming a corrosion resistant structural equipment, the method comprising:

• providing a steel composition having chemical requirements as specified according to any of ASTM and API standards, and modified by adding at least 0.05% Si to the chemical requirements of Si, for a Si content ranging from 0.30 to 3.5% by weight;
• forming a structural equipment from the steel composition such that the structural equipment complies to at least one of the ASTM standards, API standards with respect to manufacture, dimensions and weight, mechanical properties, testing, and certification of the structural equipment;
• and
• wherein the structural equipment is suitable for containing hydrocarbons in sulfur containing environments operating at a temperature ranging from 400° F. to 1000° F., and
• wherein the structural equipment has a corrosion rate of 15 mpy or less upon exposure to hydrocarbons saturated with a gas stream containing 10% H2S and 90% nitrogen at 600° F. for 72 hours.
