AISI is a hardenable chromium, molybdenum, nickel low alloy steel often used for carburizing to develop a case-hardened part. A request for an assist always results in a prompt response from the appropriate supplier expert or an answer from PMPA Staff. Mean Coeff Thermal Expansion. Posting Guidelines Promoting, selling, recruiting, coursework and thesis posting is forbidden.
The Architecture, Engineering and Construction AEC industry is constantly looking for process improvements to better manage potential project delays and costs.
The alloy may be forged at F down to F prior to the hardening heat treatment or carburizing. The time to catch an obsolete specification is during contract review, before there are commitmemnts to material and or sunk costs of material, production and inspection.
Machining is done prior to carburizing to within as close a tolerance as possible. Forming characteristics of alloy are good in the annealed condition. From there it may be air cooled.

Promoting, selling, recruiting, coursework and thesis posting is forbidden. There were over 19, cancelled or superceded specifications, commercial item descriptions and standards when I first prepared my list of Obsolete Federal Specifications for cold finished steel in Click Here to join Eng-Tips and talk with other members! Are you an Engineering professional? This case-hardening will result in good wear characteristics.
This alloy is typically used for carburized parts where a hardened case is desired for wear resistance.

Following carburizing of heavy q331 a reheat at F will enhance both case and core properties of the alloy. Is there any reference that a is the replacement std instead of a RE: From Hiden Analytical 9 Nov AISI alloy steel can be welded using a331 conventional techniques. Where do you go for an assist when wierd, strange, and unusual specifications appear in a quote package?
The Eng-Tips staff will check this a3331 and take appropriate action. I could not find reference for these in A Can this material be used in design of Spur Gears? Few production environments have the luxury of ordering new equipment to replace existing machines on their shop floor. Do you have a review, update or anything you would like to add to this article?
Register now while it’s still free! This alloy may be hardened by heating to F followed by a water quench. AISI alloy steel is chromium, molybdenum, manganese containing low asm steel.
The design specifications are: It requires more pressure or force for forming because it is tougher than plain carbon steels. The following datasheet gives an overview of AISI alloy steel.

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 Bar Products by 59 distributors but is also available to a lesser extent in Flat Rolled Products, Tubular Products, Wire Products, Forging Products, and Casting Products.
Private Feedback ast AZoM.

Tempering of carburized parts is done at to F and this will result in the alloy having a core strength of approximately ksi minimum with Rockwell C case hardness of Download Now The Architecture, Engineering and Construction AEC industry is constantly looking for process improvements to better manage potential project delays and costs.
