ASTM B729 Alloy 20 Seamless Tube 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.

Product Name: ASTM B729 Alloy 20 Seamless Tube

Our specialized process for seamless tubing manufacturing begins with either an extruded hollow tube or a solid bar drilled to our exacting specifications. The material is then reduced in size a number of times through various cold working techniques until it reaches the specific size, tolerances, and temper required by our customer. After each cold working cycle the tubes are cut, cleaned and heat treated in preparation for the next cold working step.  Seamless tubes can be created in a variety of different sizes and shapes from a wide range of alloys.

ASTM B729 Alloy 20 Seamless Tube are ideal for tubes used in some of the most demanding applications

At Piyush Steel we export & supply ASTM B729 Alloy 20 Seamless Tube & precision tubes using stainless steel, nickel, titanium and zirconium alloys, in a whole range of sizes and cross section shapes to suit your requirements. Both our seamless and welded products come both as straight lengths of tubing or in coils.

Our ASTM B729 Alloy 20 Seamless Tube, seamless and welded drawn tubes range in size from under 0.010” (1/4 mm) right up to 1.5” (38.1mm) outside diameter, and we can produce finished wall thicknesses down to less than 0.002” (0.05 mm) through to 0.150” (3.8mm).

You can order straight lengths of tubing from us up to 45ft (14m) long or coiled tubes up to 3,200ft (975m) in length.

ASTM B729 Alloy 20 Seamless Tube 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.
