ASTM B729 Alloy 20 Seamless Pipe Specification

Nickel Alloy 20, Carpenter® 20, Incoloy® 20

Alloy 20, also known as Carpenter® 20 and Incoloy® 20, is an austenitic nickel-iron-chromium alloy. This super alloy, which also includes copper and molybdenum, is popular in the production of gasoline, solvents, explosives, chemicals, pharmaceuticals and food and synthetic materials. Alloy 20 nickel tubing is a nickel-chromium-molybdenum alloy developed to resist pitting and chloride ion corrosion and its copper content protects it from sulfuric acid.

Our seamless stainless steel and nickel alloy tubes and pipes are mainly used in the following industries:

Chemical and petrochemical industry

Power generation and Environmental technologies

Oil and gas applications

Mechanical and plant engineering and construction

Automotive industry

Seamless stainless steel tubes and pipes are the preferred choice for processes under the following conditions:

- high temperatures

- aggressive media (e.g. acid and lye)

- and/or high pressure

which call for the use of high-quality materials.

 

Alloy 20 nickel tubing resists pitting and chloride ion corrosion and its copper content protects it from sulfuric acid.

Typical applications include tanks, piping, heat exchangers, pumps, valves.

ASTM B729 Alloy 20 Seamless Pipe quality certificates

ASTM B729 Alloy 20 Seamless Pipe delivered with a 3.1 certificate. we can perform the tests required to issue a 3.2 certificate, or a CMTR in accordance with the ASME III Code.

ASTM B729 Alloy 20 Seamless Pipe Packaging & Shipping

Beyond products as such, we offer some additional services quite worth having.

So, besides the fact that we can arrange freight transportation for you, we can before that:

  • specifically mark parts or packages;
  • provide for a special packing according to what is required by the shipping method or by you.

We mark the ASTM B729 Alloy 20 Seamless Pipe as needed with the most suitable marking technique.

When packaging and packing, our experienced warehouse staff systematically takes the greatest precautions for your ASTM B729 Alloy 20 Seamless Pipe to be optimally protected during transportation. We pack the ASTM B729 Alloy 20 Seamless Pipe according to the appropriate method: strapped pallet, wooden crate, overseas packing (ISPM15).

ASTM B729 Alloy 20 Seamless Pipe Useful info

Alloy 20 nickel pipe is made from a nickel-iron-chromium alloy with additions of copper and molybdenum. Contains niobium for stabilization against sensitization resulting in intergranular corrosion. Has excellent resistance to general corrosion, pitting, and crevice corrosion in chemicals,containing chlorides and sulfuric, phosphoric, nitric acids.

Alloy 20 is a nickel–chromium–molybdenum stainless steel alloy developed for applications involving sulfuric acid. Its corrosion resistance also finds other uses in the chemical, food, pharmaceutical, power generation, and plastics industries. Alloy 20 resists pitting and chloride ion corrosion and its copper content protects it from sulfuric acid. Alloy 20 is not a stainless steel but a nickel alloy (ASTM). Alloy 20 is often chosen to solve stress corrosion cracking problems, which may occur with 316L stainless.

Typical applications include tanks, piping, heat exchangers, pumps, valves.
