ASTM B161 Nickel 201 Seamless Pipe Specification

Nickel based alloys are very useful materials for the manufacture of high quality tubing products. One of the key reasons is that they offer excellent corrosion resistance in both aqueous and high temperature applications.

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.

ASTM B161 Nickel 201 Seamless Pipe quality certificates

ASTM B161 Nickel 201 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 B161 Nickel 201 Seamless Pipe Packaging & Shipping

Our staff has extensive experience in export documentation,packaging, and finance. We have found that the biggest key to a successful export transaction is communication.

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 B161 Nickel 201 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 B161 Nickel 201 Seamless Pipe to be optimally protected during transportation. We pack the ASTM B161 Nickel 201 Seamless Pipe according to the appropriate method: strapped pallet, wooden crate, overseas packing (ISPM15).

High temperature nickel based alloys

A further increase of specific alloy elements (such as chrome, molybdenum, tungsten, titanium, aluminium, niobium, etc.) improves the high temperature, high strength characteristics of austenitic steels. The disadvantage of austenitic stainless steels occurs in the fact that these elements have a reduced solubility. In order to compensate this effect and to reach the desired result, the nickel concentration can be increased. The highest alloyed types of high temperature nickel based alloys contain only a very low iron concentration.


  • Good resistance to corrosion in acids and alkalis and is most useful under reducing conditions.
  • Outstanding resistance to caustic alkalis up to and including the molten state.
  • In acid, alkaline and neutral salt solutions the material shows good resistance, but in oxidising salt solutions severe attack will occur.
  • Resistant to all dry gases at room temperature and in dry chlorine and hydrogen chloride may be used in temperatures up to 550C.
  • Resistance to mineral acids varies according to temperature and concentration and whether the solution is aerated or not. Corrosion resistance is better in de-aerated acid.
  • Virtually immune to inter granular attack above 315C, chlorates must be kept to a minimum.


  • Manufacture and handling of sodium hydroxide, particularly at temperature above 300C.
  • Production of viscose rayon. Manufacture of soap.
  • Analine hydrochloride production and in the chlorination of aliphatic hydrocarbons such as benzene, methane and ethane.
  • Manufacture of vinyl chloride monomer.
  • Reactors and vessels in which fluorine is generated and reacted with hydrocarbons.
