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 There were over 19, cancelled or superceded specifications, commercial item descriptions and standards when I first prepared my list of Obsolete Federal Specifications for cold finished steel in Click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.

Such issues are the result of project complexity, size, uniqueness and regulation, as well as the atsm for virtual team collaboration. Do you think this is a good metal for this purpose? Preheating at F is beneficial and subsequent w331 after welding is recommended – consult the approved weld procedure for the method used. Students Click Here Join Us! This site uses cookies.

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?
