Resistance to chloride stress corrosion-manufacture,factory,supplier from China

When selecting stainless steel in corrosive environment, in addition to having a detailed understanding of the specific service conditions of stainless steel, the main factors to be considered include: corrosion resistance, strength, toughness and physical properties, processing, formability, resources, price and difficulty of obtaining.Corrosion resistance includes rust resistance and resistance to acid, alkali, salt and other corrosive media, as well as oxidation resistance, vulcanization, chlorination and fluorination at high temperature.

Inconel 600 alloy has the following properties.        1. good resistance to corrosion by reducing, oxidizing and nitriding media        2. good resistance to stress corrosion cracking at both room temperature and high temperature        3. good resistance to dry chlorine and hydrogen chloride gas corrosion        4. good mechanical properties at sub-zero, room temperature and high temperature        5.

duplex (austenitic-ferritic) stainless steel characterized by:High resistance to stress corrosion cracking (SCC) in chloride-bearing environmentsHigh resistance to stress corrosion cracking (SCC) in environments containing hydrogen sulfideHigh resistance to general corrosion, pitting, and crevice corrosionHigh resistance to erosion corrosion and corrosion fatigueHigh mechanical strength - roughly twice the proof strength of austenitic stainless steelPhysical properties that offer design advantagesGood weldability

       Incoloy 925 is an age-hardened nickel-iron-chromium alloy with additions of molybdenum, copper, titanium and aluminum. The chemical composition of this alloy is designed to provide a combination of high strength and excellent corrosion resistance. The nickel content is sufficient to prevent chloride ion stress corrosion cracking. Nickel, along with molybdenum and copper, also provides significant resistance to chemical reduction. Molybdenum helps resist pitting and crevice corrosion. The chromium content of the alloy resists oxidizing environments.

Introduction:Alloys comparable to Incoloy 825 alloys are high Ni, highly corrosion-resistant nickel-based alloys with extremely high corrosion resistance to both oxidizing and non-oxidizing acids.Incoloy 825 alloy has good general corrosion resistance to both oxidizing and non-oxidizing acids due to its rich content of Cr, Mo and Cu. In particular, it has extremely high corrosion resistance to sulfuric acid. Due to the high content of Cr, Mo and Ni, it has excellent pitting corrosion resistance, crevice corrosion resistance and stress corrosion cracking resistance in chloride environment.

The  maximum not unusualplace chrome steel grades are 304 and 316. The key distinction is the addition of molybdenum, an alloy which substantially complements corrosion resistance, mainly for greater saline or chloride-uncovered environments.316 chrome steel consists of molybdenum. 304 chrome steel does not.For out of doors fixtures like rails and bollards, chrome steel is a really perfect corrosion-resistant material, however it'll most effective resist long-time period publicity if the grade is suitable for its environment.

314 stainless steel has high high temperature strength and oxidation resistance, is more sensitive to sulfur-containing atmosphere, and has a tendency to embrittlement of precipitates at 600-800 °C. It is suitable for making various furnace components under stress.316 stainless steel, 18Cr-12Ni-2.5Mo With the addition of Mo, its corrosion resistance, atmospheric corrosion resistance and high temperature strength are particularly good, and can be used under harsh conditions; excellent work hardening (non-magnetic).

Application and characteristics of HastelloyPurpose:Hastelloy plate is suitable for various chemical industries containing oxidizing and reducing media. The high content of molybdenum and chromium makes the alloy resistant to chloride ion corrosion, and tungsten further improves the corrosion resistance. At the same time, C-276 Hastelloy pipe is one of the only materials that can resist the corrosion of wet chlorine, hypochlorite and chlorine dioxide solutions.

Seawater corrosion resistant materials, and widely used in Marine engineering. However, in practical engineering application, the stainless steel connection, especially the welding area, often appears various corrosion damage, resulting in a great loss. Therefore, in this paper, according to the characteristics of seawater corrosion of stainless steel, the seawater corrosion and anticorrosion mechanism of its weld site were comprehensively analyzed and studied.

Why doesn't stainless steel rustBecause of the addition of 12.5% chromium in stainless steel composition, it can make stainless steel surface generated a layer of passivation film, prevent the metal matrix is destroyed, enhance corrosion resistance, so the surface will not rust.
