Chemical and Petrochemical

As the family of alloys collectively known as stainless steels continues to expand, so do their potential applications throughout industry.  Generally speaking it is the ability to withstand attack by highly corrosive chemicals that creates such a high level of demand for these alloys within the chemical and petrochemical industrial sectors.

In recent years, the emergence of highly-alloyed grades such as the so-called “super-austenitic”, “super-ferritic” and “duplex” grades has enabled stainless steels to compete with nickel and titanium-based alloys for service in the most demanding conditions.  Today, these two sectors account for a large percentage of total stainless steel demand.

Included in this library section you will find papers related to use in oil and gas production, petroleum refining, pulp & paper machinery, fertiliser plants and many, many more.

The role of stainless steels in petroleum refining

Petroleum refining today is unusually sophisticated in comparison to the shell stills of the 1800s, and the industry shows every indication of becoming even more complex. Chemical and mechanical engineering advances are being sought to increase product yields and improve plant operating reliability. Methods are being developed to remove potential pollutants from processes as well as products. Changing national interests among oil-producing countries are affecting sources of raw crude supplies. One result of these changes is a growing emphasis on materials engineering, and greater interest is being shown in the high-alloy, corrosion resistant steels, especially stainless steels, to cope with a wide variety of raw crudes.

Moly does the Job – Rendering Plant

A rendering plant has been using a Type 304L stainless steel (SS) heat exchanger to condense the rendering cooker gases and heat plant water. Corrosion problems led to its replacement by Mo-containing 2205 Stainless steel. This case study has been written up by IMOA consultant John Grocki of Advantage Resources Consulting. (93 Kb pdf)

Comparison of composition ranges of 316 type stainless steels

The specification of bar (to BS970) and coil / plate (to BS1449) before 1983 covered two type 316 grades: a 'low' carbon with 0.03% max (316S12) and a 'standard' carbon with 0.07% max 316S16. Both had a molybdenum content in the range of 2.25-3.0 %.

The Sugar Industry - The Ferritic Solution

The sugar industry is a striking case where ferritic stainless steels are a clearly superior and relatively low-cost alternative to the commonly-used carbon steels. From a practical point of view, the resistance of these steels to corrosion and abrasion and their strength put them streets ahead. Then, since they contain no nickel, ferritics are price-stable and relatively inexpensive. These factors combined add up to impressive Life Cycle Cost benefits.
