Nov 16, 2015 · 15 Cr-Cb ULTRA FORM Stainless Steel provides good wet corrosion resistance superior to 409 in moderately severe chloride and organic acid environments. 15 Cr-Cb ULTRA FORM Stainless Steel also provides excellent resistance to corrosion in dilute sulfuric acid and in concentrated sodium hydroxide solutions.
301 STAINLESS STEELDec 13, 2016 · of this stainless class, Type 304L Stainless Steel. A major difference is the high C content for this alloy, which can cause the weld heat-affected-zones to be susceptible to intergranular corrosion in certain environments. When a weld filler is needed, AWS E/ER 308 is most often specified. Type 301 Stainless Steel is well known in reference
316 Stainless Steel, UNS S31600 Shaped, Flat, Square, Round, Fine Wire, Plated and Bare Wire ASTM A666, AMS 5524 316 Alloy Description Alloy 316 is an austenitic chromium-nickel stainless steel containing molybdenum. This addition increases corrosion resistance, improves resistance to pitting chloride ion solutions and provide increased
ATI 316, ATI 316L, ATI 317, ATI 317LATI 316LM alloy (W.Nr. 1.4404), a 2.5% minimum Mo version of ATI 316L stainless steel, is available only by special order. Austenitic stainless steels with higher molybdenum or molybdenum plus nitrogen content which provide even greater resistance to pitting, crevice corrosion and general corrosion are also available in flat -rolled products.
ATI 321/ATI 347/ATI 348ATI 321, ATI 347 and ATI 348 stainless steels are useful in applications where the unstabilized chromium-nickel steels, such as ATI 304 stainless steels, would be susceptible to intergranular corrosion. When the unstabilized chromium-nickel steels are held in or slowly cooled through the range of 800 to 1500°F (427 to 816°C),
The Superalloy Committee of the Specialty Steel Industry of North America is a voluntary trade association representing producers of high performance alloys in North America. Committee members produce a variety of products including sheet and strip, bar, rod, and tubing, in nickel-based and other high-performance alloys at the leading edge of metals technology that are technologically
Intergranular Corrosion Courses - XpCourseIntergranular corrosion (IGC) is a selective attack in the vicinity of the grain boundaries of a stainless steel Chromium carbides can be precipitated if the stainless steel is sensitized in the temperature range 550850°C (10201560°F), for example during heat treatment or welding
Intergranular corrosion of welded joints of austenitic Aug 01, 2008 · An intergranular corrosion study of welded joints of austenitic stainless steels (AISI 304 and 316L) has been addressed. A specific small-scale electrochemical cell (minicell) has been used. Four different weldment zones have been studied.
The presence of these carbides allows for intergranular corrosion of the steel, resulting in pitting and eventual failure of the material, as can be seen in Figure 1. This intergranular corrosion and cracking can occur in environments where stainless steel would not normally be subject to corrosion.
Stainless and specialty steel - EUROFERStainless and specialty steels not possible to control carbon at a low level, titanium or niobium may be used to stablise stainless steel against intergranular corrosion. As titanium (niobium and zirconium) have greater affinity for carbon than chromium, titanium (niobium and zirconium) carbides are formed in preference to chromium carbide
THERMAK® Stainless Steel Ferritic Stainless SteelTHERMAK 17 Stainless Steel shows improved oxidation resistance and oxide adherence when compared to other 17% chromium ferritics. The high silicon and manganese, copper added alloy reduces spalling when exposed to cyclic high temperature salt conditions creating a barrier of oxide that provides protection to the steel substrate.

What is Intergranular Corrosion (IGC)? - Waterworks WholesaleSome of us are familiar with situations where stainless-steel pipelines have corroded, or more specifically cracked, on the welds. But we didnt know it had a name, let alone why it happened or how to avoid it. Intergranular corrosion is called IGC for short and Intergranular Corrosion:An Invisible Attack on Stainless Intergranular corrosion (also known as weld decay) affects stainless steel at the structural level and may not show visible signs of damage until corrosion has significantly progressed. Welding, improper heat treatments, and exposure to temperatures between 425°C and 870°C (887°F to 1598°F) are required to initiate an intergranular attack.
