What is the specific density of 2507 duplex stainless steel pipe? What is the calculation method?

Before we know the density specific gravity of 2507 duplex stainless steel pipe, let’s take a look at what is 2507 duplex stainless steel.

2507 duplex stainless steel pipe is a kind of high alloy super duplex stainless steel (2507 duplex steel for short). 2507 super duplex stainless steel is composed of 25% chromium, 4% molybdenum and 7% nickel. At present, the domestic 2507 dual-phase steel products include welded pipe, seamless pipe, steel plate, bar, forging, strip, etc.

Let’s take 2507 duplex stainless steel pipe as an example to introduce the density of 2507 duplex steel?

What is the specific density of 2507 duplex stainless steel pipe? What is the calculation method?

Physical and mechanical properties of 2507 super duplex stainless steel:

1. 2507 dual-phase steel density: 8.0g/cm3.
2. Tensile strength of 2507 duplex steel: σ b≥800Mpa。
3. 2507 dual-phase steel yield strength: σ 0.2≥550Mpa
4. 2507 dual-phase steel elongation: δ≥ 15%。
5. 2507 duplex steel hardness (HB): 310

Theoretical weight calculation formula of 2507 duplex steel plate:

Weight (kg)=thickness (mm) * width (m) * length (m) * density value

The impact strength of 2507 duplex stainless steel pipe is also very high. It is not suitable for use at temperatures higher than 570 ℃. Its toughness will be reduced if it is exposed to such environment for a long time. The 2507 duplex stainless steel pipe also combines the most beneficial properties of many ferritic and austenitic steels. Because of the high content of chromium and molybdenum, the steel has excellent resistance to spot corrosion, crevice corrosion and uniform corrosion. The duplex microstructure ensures that the steel has high resistance to stress corrosion cracking and high mechanical strength
