This superalloy has excellent resistance to general corrosion, pitting, and crevice corrosion in chemicals containing chlorides and sulfuric, phosphoric, and nitric acids.

It is intended for reference and general information and not recommended for specification, design or engineering purposes. So, depending on who you talk to this alloy may be referred to as alloy 20 Stainless Steel or as a nickel alloy. There has long been a debate on whether Carpenter 20 is a stainless steel or a nickel alloy because the nickel content is right on the border of defining it as one way or the other. China sg2 welding wire China aluminum welding wire China copper free welding wire.

In what forms is Alloy 20 Available at Mega Mex? High Performance Alloys stocks and produces this grade in the following forms: Its elevated strength may require higher forming pressures.

CARPENTER® alloy 20Cb-3® (UNS N08020)

Besides sulfuric acid related processes, some typical corrosion resistant applications for the alloy include chemical, pharmaceutical, food, plastics, synthetic fibers, pickling and FGD systems plus many others.

We believe the information and data provided to be accurate to the best of our knowledge but, all data is considered typical values only. Soak thoroughly at F C. Alloy 20 is used is a wide variety of applications from Sulfuric acid pickling tanks, racks and heating coil, Heat Exchangers, Process piping, Chemical and petroleum process equipment etc.


Good asfm at astn the mill and distributor levels have made this a popular choice for a wide variety of applications.

China welding wire drums China co2 welding wire price China aluminum bronze welding wire. A soap finish is available in tempered products. Soap is used as a lubricant in the drawing process and is not removed. It acts as a lubricant during customer part forming operation. Alloy 20 is a highly alloyed iron-base nickel-chromium-molybdenum stainless steel developed primarily for use in the sulfuric acid related processes.

This material may only be hardened by cold work. Understand, however, that this process will adversely affect the stability of the material. Without this process, the material can be satisfactorily formed albeit with a high work hardening rate.

Components for processing synthetic rubber processing Components for processing gasoline, solvents, explosives, plastics, synthetic fibers, chemicals Food and dye production Components for processing pharmaceutical. Balance Physical Properties Density, 0. Carpenter 20 combines excellent corrosion resistance with elevated mechanical properties and relatively easy fabrication.

Alloy 20, also known as Carpenter 20, is a nickel-iron-chromium austenitic alloy that was developed for maximum resistance to acid attack, specifically sulfuric acid. Although originally designed for use in sulfuric acid related industries, Alloy 20 is now a popular choice for a wide variety of industries including the chemical, food, pharmaceutical, and plastics industries.

Bar, wire, sheet, plate, coil, fasteners and forgings. Either way it is still great for corrosion resistance. For best results refer to: The presence of columbium tends to minimize the precipitation of carbides in the heat affected zone, so the material may, in most casesbe used in the “as welded” condition.


Humble, Texas fax Alloy 20 CB-3 stainless is also stabilizes to limit inter-granular attack, even in the sensitized condition. Ni 35, Fe 37, Cr 20, Cu 3.
