Duplex Stainless Steel Corrosion Resistance-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.

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

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.

Duplex Stainless Steels are a specific group of engineering stainless steel materials consisting of the austenitic and ferritic phase in roughly equal proportions in the microstructure. They are widely popular because of their good corrosion resistance along with high strength and ease of fabrication. They are also popular by their acronym DSS.

Advantages Of Stainless Steel Veneer And Need To Pay Attention To The Place.Stainless steel veneer because of its high strength, can be used for high-rise and super high-rise buildings; Toughness, can do bending or bending arc processing, can achieve more architectural appearance effect, this is stainless steel composite plate and stainless steel honeycomb plate is not easy to achieve; Strong corrosion resistance, convenient maintenance.▲ Stainless steel veneer curtain wall project Stainless steel veneer as a metal component in addition to adapt to cutting, grooving, bending and other pro

Corrosion resistanceInternational corrosion resistance of materials according to the annual corrosion rate is divided into three categories, the first category for complete corrosion resistance, the corrosion rate is less than 0.1mm / year, high-quality stainless steel belongs to such materials; the second category for still corrosion resistance, the corrosion rate of 0.1-1.0mm / year, belongs to the general stainless steel; the third category for corrosion resistance, the corrosion rate is greater than 1.0mm per year.Cold rolled descriptionCold rolled: Hot rolled coil is used as raw material,

What is the difference between 2507 stainless steel plate and 2205 and 2206? 2507 stainless steel tube is a ferritic - austenitic (duplex) stainless steel, which combines many of the most beneficial properties of ferritic and austenitic steels. Due to the high content of chromium and molybdenum in the steel, it has excellent resistance to spot corrosion, gap corrosion and uniform corrosion.
