Distributors will offer small quantity buys while mills will generally only sell large quantities, with delivery times anywhere from 10 to 50 weeks depending on size and form required This material is stocked primarily in Tubular Products by 24 distributors but is also available to a lesser extent in Piping Components, Flat Rolled Products, Bar Products, Wire Products, Forging Products, Fasteners, and Structurals. b417

Alloy 20 Stainless Steel Material Property Data Sheet – Product availability and request a quote

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

Soak thoroughly at F Cwater quench. We believe the information and data provided to be accurate to the best of our knowledge but, all data is considered typical values only. 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.

Modulus of Elasticity Tension. The presence of Columbium in the alloy minimizes the precipitation of carbides during welding. It is intended for reference and general information and not recommended for specification, design or engineering purposes.

Packaging Details Standard seaworthy package wooden boxes package,pvc package, and other package. Slow speeds and heavy, constant feeds are the rules in working this alloy.


This alloy can be successfully cold formed using all common practices. Either way it is still great for corrosion resistance. Many plating options are available. Soak thoroughly at F C.

Standard Wire Finishes Extra Clean: This alloy is a columbium stabilized material that combines excellent corrosion resistance with elevated mechanical properties and relatively easy fabrication.

CARPENTER® alloy 20Cb-3® (UNS N08020)

Its nickel, chromium, molybdenum and copper levels all provide excellent general corrosion resistance. Overview Alloy 20 is a highly alloyed iron-base nickel-chromium-molybdenum stainless steel developed primarily for use in the sulfuric acid related processes.

Also employed in heat exchangers, mixing tanks, metal cleaning and pickling equipment and process piping. Soap is used as a lubricant in the drawing process and is not removed. For best results refer to: Machining Type Suggested starting rates are: These rates are for carbide tools, Type C-2 for roughing, drilling and reaming.

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

Bar, wire, sheet, plate, coil, fasteners and forgings. Electrical Resistivity microhm-cm at 68 Deg F. Re-heat when temperature drops below F C.

Alloy 20 CB-3 stainless is also stabilizes to limit inter-granular attack, even in the sensitized condition.

CARPENTER alloy 20Cb-3

Most commonly used welding methods with the exception of oxyacetylene welding have been successfully employed with this alloy. Annealed Ultimate Tensile Asttm Reproduction of this site in whole or part is prohibited without the expressed permission of High Performance Alloys, Inc.

Forms Continuous Coils Cut to lengths Precision cutting. This alloy can be successfully hot formed using forces similar to those required by austenitic stainless steels.

Type C-3 for finishing. Important advantages of alloy 20 CB-3 stainless are its excellent mechanical properties and comparative ease of fabrication.


China welding wire drums China co2 welding wire price China aluminum bronze welding wire. This material may only be hardened by cold work.

Balance Physical Properties Density, 0. It acts as a lubricant during customer part forming operation. Ni 35, Fe 37, Cr 20, Cu 3. After forging, reheat and soak completely at F C and quench rapidly in water or oil.

Humble, Texas fax 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. Components for processing synthetic rubber processing Components for processing gasoline, solvents, explosives, plastics, synthetic fibers, chemicals Food and dye production Components for processing pharmaceutical.

Request quote on this grade. Agree to Terms of Service. In what forms is Alloy 20 Available at Mega Mex? Its elevated strength may require higher forming pressures. China tin welding wire China copper welding wire China flux cored welding wire.

It particularly excels in resisting corrosion to hot sulfuric acids when compared to conventional stainless steels such as Pre-heating is not required. Alloy 20 is a highly alloyed austenitic stainless steel developed primarily for use in the sulfuric acid related processes.

So, depending on who you talk to this alloy may be referred to as alloy 20 Stainless Steel or as a nickel alloy. A soap finish is available in tempered products.
