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. Contact Ulbrich Wire for details.

Standard Wire Finishes Extra Clean: Mechanical Property Requirements Ultimate Tensile, min. China sg2 welding wire China aluminum welding wire China copper free welding wire. This alloy can be successfully cold formed using all common practices.

Electrical Resistivity microhm-cm at 68 Deg F. Alloy 20 Chemical composition. China tin welding wire China copper welding wire China flux cored welding wire. 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.

Superior finishes may be obtained using set-up and process speeds and feeds normally employed in austenitic stainless steels such as and Included among these are: 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.


High Performance Alloys stocks and produces this grade in the following forms: It also contains niobium for stabilization against sensitization and resultant intergranular corrosion. 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. Alloy 20 is a highly alloyed austenitic stainless steel developed primarily for use in the sulfuric acid related processes.

This alloy can be successfully hot formed using forces similar to those required by austenitic stainless steels. Ulbrich assumes no implied or express warranty in regard to the creation or accuracy of the data provided in this document. So, depending on who you talk to this alloy may be referred to as alloy 20 Stainless Steel or as a nickel alloy. Important advantages of alloy 20 CB-3 stainless are its excellent mechanical properties and comparative ease of fabrication.

It acts as a lubricant during customer part forming operation. China welding wire drums China co2 welding wire price China aluminum bronze welding wire. It particularly excels in resisting corrosion to hot sulfuric acids when compared to conventional stainless steels such as Please give us a Review. Understand, however, that this process will adversely affect the stability of the material.

It is intended for reference and general information and not recommended for specification, design or engineering purposes.

CARPENTER alloy 20Cb-3

Megamex is a metal supplier for hastelloy, monel, inconel, stainless steel, carbon steel, metal fabrication, nickel alloys, and more. Forms Continuous Coils Cut to lengths Precision cutting.


In what forms is Alloy 20 Available at Mega Mex? This superalloy has excellent resistance to general corrosion, pitting, and crevice corrosion in chemicals containing chlorides and sulfuric, phosphoric, and nitric acids. Restricted carbon plus columbium stabilization permits welded fabrications qstm be used in corrosive environments, normally without post-weld heat treatment.

Soak thoroughly at F Cwater quench. Although originally designed for use in sulfuric asym related industries, Alloy 20 is now a popular choice for a wide variety of industries including the chemical, food, pharmaceutical, and plastics industries. Its axtm, chromium, molybdenum and copper levels all provide excellent general corrosion resistance. Also employed in heat exchangers, mixing tanks, metal cleaning and pickling equipment and process piping. A soap finish is asgm in tempered products.

Alloy 20 Mechanical properties: Annealed Ultimate Tensile Strength: Not exactly what you want? Either way it is still great for corrosion resistance. This alloy is a columbium stabilized material that 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.
