Duplex Stainless Steel Composition Table-manufacture,factory,supplier from China

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.

Laying points of stainless steel elbow in pipeline:1. In order to reduce the heat loss of the stainless steel elbow and prevent thermal deformation, the buried depth of the pipeline should be greater than 1.2 meters. (calculated from the top of the pipe). The burial depth in alpine regions should be appropriately deepened. At the same time, all pipes should be avoided to be laid below the water table.2. For areas where the groundwater level is high or it is difficult to dig deep for other reasons, measures should be taken as far as possible to avoid water insulators before burying the pipes.

All steels have the identical primary iron and carbon composition, however stainless-steel additionally includes a healthful dose of chromium—the alloy that offers stainless-steel its well-known corrosion resistance.There are a couple of grades known as stainless-steel, every with barely exclusive alloy composition, and consequently barely exclusive bodily characteristics.Stainless metallic need to comprise at the least 10.five percentage chromium.

What is stainless steel?All steels have the same basic iron and carbon composition, but stainless steel also contains a healthy dose of chromium—the alloy that gives stainless steel its famous corrosion resistance.There are multiple grades called stainless steel, each with slightly different alloy composition, and therefore slightly different physical characteristics.Stainless steel must contain at least 10.5 percent chromium.

Depending on the grade, it may contain much higher chromium levels, and additional alloying ingredients like molybdenum, nickel, titanium, aluminum, copper, nitrogen, phosphorous or selenium.

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

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.
