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

This alloy is a columbium stabilized material that combines excellent corrosion resistance with elevated mechanical properties and relatively easy fabrication. Many plating options are available. 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. Restricted carbon plus columbium stabilization permits welded fabrications to be used in corrosive environments, normally without post-weld heat treatment.


Humble, Texas fax This alloy can be successfully hot formed using forces similar to those required by austenitic stainless steels. In what forms is Alloy 20 Available at Mega Mex? 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 of Columbium in the alloy minimizes the precipitation of carbides during welding. Alloy 20 is a highly alloyed austenitic stainless steel developed primarily for use in the sulfuric acid related processes. Agree to Terms of Service. This superalloy has excellent resistance to general corrosion, pitting, and crevice corrosion in chemicals containing chlorides and sulfuric, phosphoric, and nitric acids.

Carpenter 20 combines excellent corrosion resistance with elevated mechanical properties and relatively easy fabrication.

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

It is intended for reference and general information and not recommended for specification, design or engineering purposes. High Performance Alloys stocks and produces this grade in aetm following forms: Understand, however, that this process will adversely affect the stability of the material. China welding wire drums China co2 welding wire price China aluminum bronze welding wire. Not exactly what you want?

Either way it is still great for corrosion resistance. Request quote on this grade. Modulus of Elasticity Tension. Without this process, the material can be satisfactorily formed albeit with a high work hardening rate. Balance Physical Properties Density, 0. 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.

Jiangsu Xinhua Alloy Electric Co. Alloy 20 Mechanical properties: It also contains niobium for stabilization against sensitization and resultant intergranular corrosion. Although normally considered a stainless steel, it has been classified as a nickel base. Its elevated strength may require higher forming pressures. Mechanical Property Requirements Ultimate Tensile, min. In addition, this superalloy is used in heat exchangers, mixing tanks, metal cleaning and pickling equipment, and piping.


Forms Continuous Coils Cut to lengths Precision cutting. This material may only be hardened by cold work.

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.

Machining Type Suggested starting rates are: Soak thoroughly at F Cwater quench. Soap is used as a lubricant in the drawing process and is not removed.

Most commonly used welding methods with the exception of oxyacetylene welding have been successfully employed with this alloy. Alloy 20 is a highly alloyed iron-base nickel-chromium-molybdenum stainless steel developed primarily for use in the sulfuric acid related processes.

Type C-3 for finishing. Standard Wire Finishes Extra Clean: China sg2 welding wire China aluminum welding wire China copper free welding wire. For best results refer to: After forging, reheat and soak completely at F C ashm quench rapidly in water or oil. Alloy 20, also known as Carpenter 20, is 4b71 nickel-iron-chromium austenitic alloy that was developed for maximum resistance to acid attack, specifically sulfuric acid.
