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. Electrical Resistivity microhm-cm at 68 Deg F.

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

CARPENTER alloy 20Cb-3

So, depending on who you talk to this alloy may be referred to as alloy 20 Stainless Steel or as a nickel alloy. Ni 35, Fe 37, Cr 20, Cu 3. 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.

Annealed Ultimate Tensile Strength: This alloy is a columbium stabilized material that combines excellent corrosion resistance with elevated mechanical properties and relatively easy fabrication.

Either way it is still great for corrosion resistance.

Carpenter 20 CB-3® Stainless Steel UNS N08020

Understand, however, that this process will adversely affect the stability of the material. Forms Continuous Coils Cut to lengths Precision cutting. Type C-3 for finishing.

Carpenter 20 combines excellent corrosion resistance with elevated mechanical properties and relatively easy fabrication. Although normally considered a stainless steel, it has been classified as a nickel base. Not exactly what you want?


Its nickel, chromium, molybdenum and copper levels all provide excellent general corrosion resistance. Mechanical Property Requirements Ultimate Tensile, min. Alloy 20 Mechanical properties: In addition, this superalloy is used in heat exchangers, mixing tanks, metal cleaning and pickling equipment, and piping.

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. In what forms is Alloy 20 Available at Mega Mex? Machining Type Suggested starting rates are: Contact Ulbrich Wire Sales with special finish and plating requests.

Good availability at both the mill and distributor levels have made this a popular choice for a wide variety of applications. Applications Components for processing synthetic rubber processing Components for processing gasoline, solvents, explosives, plastics, synthetic fibers, chemicals Food and dye production Components for processing pharmaceutical Chemistry Typical Carbon: Many plating options are available. Superior finishes may be obtained using set-up and process speeds and feeds normally employed in austenitic stainless steels such as and Re-heat when temperature drops below F C.

Megamex is a metal supplier for hastelloy, monel, inconel, stainless steel, carbon steel, metal fabrication, nickel alloys, and more. Most commonly used welding methods with the exception of oxyacetylene welding have been successfully employed with this alloy.

Packaging Details Standard seaworthy package wooden boxes package,pvc package, and other package.

To obtain maximum ductility, heat material to F C. China welding wire drums China co2 welding wire price China aluminum bronze welding wire. Soak thoroughly at F C. Alloy 20 Chemical composition. Request quote on this grade. After forging, reheat and soak completely at F C and quench rapidly in water or oil. We believe the information and data provided to be accurate to the best of our knowledge but, all data is considered typical values only.


The presence asmt Columbium in the alloy minimizes the precipitation of carbides during welding. Please give us a Review. Included among these are: Alloy 20 is used is a wide ast, of applications b71 Sulfuric acid pickling tanks, racks and heating coil, Heat Exchangers, Process piping, Chemical and petroleum process equipment etc.

It is intended for reference and general information and not recommended for specification, design or engineering purposes. It also contains niobium for stabilization against sensitization and resultant intergranular corrosion. Soap is used as a lubricant in the drawing process and is not removed. 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.

Slow speeds and heavy, constant feeds are the rules in working this alloy. Modulus of Elasticity Tension. This material may only be hardened by cold work. Important advantages of alloy 20 CB-3 stainless are its b4711 mechanical properties and comparative ease of fabrication.

Soak thoroughly at F Cwater quench. Alloy 20 is a highly alloyed austenitic stainless steel developed primarily for use in the sulfuric acid related processes. 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 adtm way or the other. Restricted carbon plus columbium stabilization permits welded fabrications to be used in corrosive environments, normally without post-weld heat treatment.
