Alloy Steel Inoconel 725 alloy steel plate bar pipe wire
Product Description
Inoconel 725 alloy steel plates rods pipes bars forgings This alloy is nickel-chromium-molybdenum-niobium alloy with excellent corrosion resistance. After aging heat treatment, the strength of the alloy can be greatly increased, and the ductility and tensile resistance of the alloy can be greatly improved.The alloy also has strong resistance to stress corrosion.Used for pipe fittings, joints and bearings in acid-resistant equipment.It is also widely used in Marine equipment.

Nickel-based alloy is a kind of alloy with high strength and corrosion resistance at 650 ~ 1000℃.
It is further subdivided into nickel-based heat resistant alloys, nickel-based corrosion resistant alloys, nickel-based wear resistant alloys, nickel-based precision alloys and nickel-based shape memory alloys.
According to different substrates, superalloys can be divided into iron - based superalloys, nickel - based superalloys and cobalt - based superalloys.
Nickel-based superalloy is referred to as nickel-based alloy.
Representative materials of nickel-based alloys are:
1. Incoloy alloy, such as Incoloy800, is mainly composed of;32 ni - cr - 21 Ti, Al;It belongs to heat-resistant alloy;
2. Inconel alloy, such as Inconel600, mainly consists of:Ni - cr 15-73 Ti, Al;It belongs to heat-resistant alloy;
3. Hastelloy alloy, namely Hastelloy alloy, such as Hastelloy c-276, is mainly composed of:56 ni - cr - 16 of 16 mo - 4 w;Corrosion resistant alloy;
4. Monel alloy, i.e. Monel alloy, such as Monel 400, is mainly composed of;34 cu ni - 65;Corrosion resistant alloy;
At 650 ~ 1000℃ high temperature, it has high strength and certain anti-oxidation corrosion ability. Due to high enough high temperature strength and anti-oxidation corrosion ability, it is often used to manufacture high temperature parts on aircraft engine blades and rocket engines, nuclear reactors and energy conversion equipment.
