Alloy 20 is a highly alloyed austenitic stainless steel developed primarily for use in the sulfuric acid related processes.

Most commonly used welding methods with the exception of oxyacetylene welding have been successfully employed with this alloy. The presence of Columbium in the alloy minimizes the precipitation of carbides during welding. Standard Wire Finishes Extra Clean: Request quote on this grade. Soak thoroughly at F C. It particularly excels in resisting corrosion to hot sulfuric acids when compared to conventional stainless steels such as For best results refer to: 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.

Re-heat when temperature drops below F C. Balance Physical Properties Density, 0. Contact Ulbrich Wire for details. Its elevated strength may require higher forming pressures.

Alloy 20 is a highly alloyed iron-base nickel-chromium-molybdenum 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 one way or the other.

Humble, Texas fax Important advantages of alloy 20 CB-3 stainless are its excellent mechanical properties and comparative ease of fabrication. These rates are for carbide tools, Type C-2 for roughing, drilling and reaming. Restricted carbon plus columbium stabilization permits welded fabrications to be used in corrosive environments, normally without post-weld heat treatment.

In what forms is Alloy 20 Available at Mega Mex? Ni 35, Fe 37, Cr 20, Cu 3. Also employed in heat exchangers, mixing tanks, metal cleaning and pickling equipment and process piping.

High Performance Alloys stocks and produces this grade in the following forms: Electrical Resistivity microhm-cm at 68 Deg F.

This material may only be hardened by cold work. It also contains niobium for stabilization against sensitization and resultant intergranular corrosion. Pre-heating is not required. Without this process, the material can be satisfactorily formed albeit with a high work hardening rate. Its nickel, chromium, molybdenum and copper levels all provide excellent general corrosion resistance.

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. 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.

Machining Type Suggested starting rates are: 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.

Asgm 20 combines excellent corrosion resistance with elevated mechanical properties and relatively easy fabrication. Good availability at both the mill and distributor levels have made this a popular choice for a wide variety of applications.

It acts as a lubricant during customer part forming operation. This alloy is a columbium stabilized material that combines excellent corrosion resistance with elevated mechanical properties and relatively easy fabrication.

A soap finish is available in tempered products.
