Contact Ulbrich Wire asmt details. Leave this field blank. Pre-heating is not required. This superalloy has excellent resistance to general corrosion, pitting, and crevice corrosion in chemicals containing chlorides and sulfuric, phosphoric, and nitric acids.

We believe the information and data provided to be accurate to the best of our knowledge but, all data is considered typical values only. Contact Ulbrich Wire Sales with special finish and plating requests. 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.

It is intended for reference and general information and not recommended for specification, design or engineering purposes. Included among these are: The presence of Columbium in the alloy minimizes the precipitation of carbides during welding. It particularly excels in resisting corrosion to hot sulfuric acids h471 compared to conventional stainless steels such as A soap finish is available in tempered products.


Packaging Details Standard seaworthy package wooden boxes package,pvc package, and other package. High Asfm Alloys stocks and produces this grade in the following forms: Not exactly axtm you want?

CARPENTER® alloy 20Cb-3® (UNS N08020)

Important advantages of alloy 20 CB-3 stainless are its excellent mechanical properties and comparative ease of fabrication. Bar, wire, sheet, plate, coil, fasteners and forgings.

This alloy can be successfully cold formed using all common practices.

After forging, reheat and soak completely at F C and quench rapidly in water or oil. Alloy 20 Mechanical properties: Reproduction of this site in whole or part is prohibited without the expressed permission of High Performance Alloys, Inc.

Re-heat when temperature drops below F C. China welding wire drums China co2 welding wire price China aluminum bronze welding wire. Electrical Resistivity microhm-cm at 68 Deg F.

Balance Physical Properties Density, 0. To obtain maximum ductility, heat material to F C. Restricted carbon plus columbium stabilization permits welded fabrications to be used in corrosive environments, normally without post-weld heat treatment.

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. Ni 35, Fe 37, Cr 20, Cu 3. Soap is used as a lubricant in the drawing process and is not removed.


These rates are for carbide tools, Type C-2 for roughing, drilling and reaming. Besides sulfuric acid related processes, some typical corrosion h471 applications for the alloy include chemical, pharmaceutical, food, plastics, synthetic fibers, pickling and FGD systems plus many others.

Machining Type Suggested starting rates are: This material may asmt be hardened by cold work.
