CARPENTER alloy 20Cb-3

Superior finishes may be obtained using set-up and process speeds and feeds normally employed in austenitic stainless steels such as and Restricted carbon plus columbium stabilization permits welded fabrications to be used in corrosive environments, normally without post-weld heat treatment.

Alloy 20 Chemical composition. Alloy 20 is a highly alloyed iron-base nickel-chromium-molybdenum stainless steel developed primarily for use in the sulfuric acid related processes. China tin welding wire China copper welding wire China flux cored welding wire.

Electrical Resistivity microhm-cm at 68 Deg F. Without this process, the material can be satisfactorily formed albeit with a high work hardening rate. Alloy 20, also known as Carpenter 20, is a nickel-iron-chromium austenitic alloy atsm was developed for maximum resistance to acid attack, specifically sulfuric acid.

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

China welding wire drums China co2 welding wire price China aluminum bronze welding wire. Please give us a Review. Standard Wire Finishes Extra Clean: These rates are for carbide tools, Type C-2 for roughing, drilling and reaming.


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. After forging, reheat and soak completely at F C and quench rapidly in water or oil. Its nickel, chromium, molybdenum and copper levels all provide excellent general corrosion resistance.

Jiangsu Xinhua Alloy Electric Co. Soak thoroughly at F B41water quench. 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: In addition, this superalloy is used in heat exchangers, mixing tanks, metal cleaning and pickling equipment, and piping.

Overview Alloy 20 is a highly alloyed iron-base nickel-chromium-molybdenum stainless steel developed primarily for use in the sulfuric acid related processes. ast

Type C-3 for finishing. Agree to B47 of Service. Although normally considered a stainless steel, it has been classified as a nickel base. This superalloy has excellent resistance to general corrosion, pitting, and crevice corrosion in chemicals containing chlorides and sulfuric, phosphoric, and nitric acids.

The presence of Columbium in the alloy minimizes the precipitation of carbides during welding.

Re-heat when temperature drops sstm F C. High Performance Alloys stocks and astj this grade in the following forms: 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.


Soap is used as a lubricant in the drawing process and is not removed. Understand, however, that this process will adversely affect the stability of the material. To obtain maximum ductility, heat material to F C. Carpenter 20 combines excellent corrosion resistance with elevated mechanical properties and relatively easy fabrication.

Machining Type Suggested starting rates are: Also employed in heat exchangers, mixing tanks, metal cleaning and pickling equipment and process piping. Soak thoroughly at F C. This alloy can be successfully hot formed using forces similar to those required by austenitic stainless steels. Request quote on this grade.

Forms Continuous Coils Cut to lengths Precision cutting.

Distributors will offer small quantity buys while mills will generally only sell large asgm, 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.
