Austenitic Iron Castings & NI Resist Cast Iron - Durham These include good scaling resistance, high resistance to heat, good thermal expansion characteristics, resistance to corrosion in seawater and alkaline liquids and atmospheres, good cold toughness and resistance to erosion. Molybdenum improves high-temperature performance. The ability to influence such a wide range of properties has meant
high temperature cases, because of its high thermal resistance. Table 1 provides an overview of corrosion resistances of the most common used coating materials for electrically conductive surfaces and the base material copper . Table 1. Corrosion resistance of selected metals:1 = high; 2 = fair; 3 = poor. Material H 2 S SO 2 Cl 2 /4 d
Corrosion and scale at high pressure high temperature Jan 01, 2017 · A detailed study on pitting resistance of corrosion resistant alloys is described. Cyclic polarization measurements were conducted at temperature up to 250°C and total dissolved solids up to 180,000 mg/L. Results suggest that the pitting resistance equivalent number may not be reliable as the criteria for evaluation of the localized corrosion
Do Metals Lose Tensile Strength as Corrosion Resistance The temperature extremes of a heat treat cycle often demand high temperature tolerances and resistance to scaling while the chemicals and vibrations used in ultrasonic processes might demand greater corrosion resistance and durability. One compromise is to use two different baskets.
the corrosion resistance of more expensive high Ni-Cr-Mo alloys in many environments. Cronifer 1925hMo (UNS N08926) was derived from the 31 is resistant at room temperature up to a con-centration of 8%, with corrosion rates below the 0.13 mm/y (5 mpy). 5 is demonstrating excellent performance. The
High Temperature Materials Corrosion Challenges for high temperature corrosion processes are also increased. In this paper, corrosion better oxidation performance in LOCA. that SiC, high Cr (>20 wt%) alloys or Al-forming alloys all show significantly improved oxidation resistance at high temperature LOCA conditions. The oxide scale thickness generated in 8 h at 1200°C
High Temperature Sulfidation Corrosion - 99 DiseasesJul 01, 2004 · High temperature sulfidation is probably the most common high temperature corrosion nemesis in the refining industry, since there are very few sweet refineries still in operation. Sulfidation corrosion typically is of concern in sour oil services starting at temperatures in the 500F (260C) range.
of the high-performance stainless steels. There are three primary classifications within the high-performance stainless steels. They are the austenitic, ferritic, and duplex (austenitic-ferritic) families. The stainless steels in each family have general similarities, but there is also a wide range of corrosion resistance and other characteristics.
High-Performance Alloys for Resistance to Aqueous treatments, improves resistance to pitting and crevice corrosion, and increases high temperature strength. Tungsten Improves resistance to reducing acids and to localized corrosion, and enhances both strength and weldability. Nitrogen Enhances metallurgical stability, improves pitting and crevice corrosion resistance, and increases strength.

Allows wide operating temperature range - outstanding high and low temperature performance. Provides thicker fluid films protecting against wear of equipment parts operating at high temperature. Causes low resistance during start-up at very low temperatures. Excellent protection against wear and corrosion
Oxidation Resistance - an overview ScienceDirect TopicsStephen A. Rackley, in Carbon Capture and Storage (Second Edition), 2017. Corrosion resistance. The oxidation resistance of steel is primarily a result of the chromium content, and to a lesser extent, in austenitic steels, the high nickel content. Chromium on the steel surface is oxidized to form an invisibly thin layer of chromium oxide (Cr 2 O 3), and this so-called passivation layer will be
Properties of Polyimides - polymerdatabasePoly(ether)imides (PEI) Properties. Poly(ether)imides (PI, PEI) are high performance engineering thermoplastics of amber to transparent color. They have outstanding thermal, mechanical, and chemical properties and are often the best choice for the most demanding applications where very high mechanical strength in combination with high temperature, corrosion, and wear resistance is required.
Jan 08, 2002 · Resistance to oxidation, or scaling, is dependent on the chromium content in the same way as the corrosion resistance is, as shown in the graph below. Most austenitic steels, with chromium contents of at least 18%, can be used at temperatures up to 870°C and Grades 309, 310 and 2111HTR (UNS S30815) even higher.
