The high chromium, molybdenum and nitrogen contents results in a Pitting Resistance Equivalent number (PREN) of 33-34, providing pitting and crevice corrosion resistance superior to Alloy 316L in almost all corrosive media.

An Intro to Pipeline Corrosion in Seawater

Mar 27, 2014 high level pitting resistance steel 625 pipenbsp; high level pitting resistance steel 625 pipe#0183; high level pitting resistance steel 625 pipe#32;For example, stainless steel type 304, which is a commonly used stainless steel, is not safe against the pitting corrosion in seawater. The pitting resistance of stainless steel increases to an acceptable value when 2% molybdenum is added to the chemical composition of stainless steel, which results in stainless steel type 316. Chloride/Chlorine Levels and Stainless Steel Alloy The 304 and 304L (18-8 stainless steel alloys) have been utilized very successfully in fresh waters containing low levels of chloride ion of up to 100 ppm. This level of chloride is considered to be the limit for the 18-8 alloys, particularly if crevices are present. Higher levels of chloride might cause crevice corrosion and pitting.

Inconel 625 Material Datasheet

Inconel 625 is a corrosion and oxidation resistant nickel alloy that is used both for both its high strength and its aqueous corrosion resistance. Its outstanding strength and toughness is derived from the stiffening effect of molybdenum and niobium on its nickel-chromium matrix.

Alloy 625 is also being considered in advanced reactor concepts because of its high allowable design strength at elevated temperatures

Inconel 625:Properties, Applications and Production

Inconel 625 is a high-performance nickel-chromium-molybdenum alloy known for its high level of strength, temperature resistance, and corrosion resistance. This superalloy is composed mainly of nickel (58% min.) followed by chromium, and molybdenum, niobium, iron, tantalum, cobalt, and trace amounts of manganese, silicon, aluminium, and titanium.

However, little data is available for alloys 625, C-276 and B-2. Available data for alloy B-2 suggests that it is resistant to all concentrations of caustic up to 70% at 250 o F/121 o C, with corrosion rates of

What is A Pitting Resistance Equivalent Number (PREN

Pitting corrosion resistance is an essential attribute to consider when choosing components and materials for a piping system. However, resistance levels change based on metallurgic composition and with the sheer variety of options available today, having a clear idea of corrosion resistance just by name or grade is nearly impossible. Alloy 625 - Corrosion MaterialsAlloy 625 is a Ni-Cr-Mo alloy that is used for its high strength, high toughness, and its oxidation and corrosion resistance. Strength of alloy 625 is derived from the stiffening effect of molybdenum and niobium on its nickel-chromium matrix. Although the alloy was developed for high
