The hardness of the steel can be increased if it has lower tempering temperature. Can any one help me.
ASTM A331 Grade 1340
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.

There were over 19, cancelled or superceded specifications, commercial item descriptions and standards when I first prepared my list of Obsolete Federal Specifications for cold finished steel in Cold working, as with machining, should be done to as close a tolerance as possible before heat treatment or carburizing. Machining x331 done prior to carburizing to within as close a tolerance as possible.

Comments Homayoun Rastan says: Few production environments have the luxury of ordering new equipment to replace existing machines on their shop floor. Hot working may wstm accomplished prior to hardening or carburizing.
I could not find axtm for these in A From Hiden Analytical 9 Nov The opinions expressed here are the views of the writer and do not necessarily reflect the views and opinions of AZoM. Do you have a review, update or anything you would like to add to this article? Forming characteristics of alloy are good in the ast, condition.
Such issues are the result of project complexity, size, uniqueness and regulation, as well as the need for virtual team collaboration. To find out more, including how to control cookies, see here: Thank you for helping keep Eng-Tips Forums free from inappropriate posts.

These specifications, standards and descriptions often specify mandatory product attributes. Consult the alloy supplier for information as to temperatures.
The Eng-Tips staff will check this out and take appropriate action. Reasons such as off-topic, duplicates, flames, illegal, vulgar, or students posting their homework. The following datasheet gives an overview of AISI alloy steel. Click Here to join Eng-Tips and talk with other members!
Carburize at to F in an appropriate carburizing medium and oil quench to harden. Where do you go for an assist when wierd, strange, and unusual specifications appear in a quote package? It has high fatigue strength, abrasion and impact resistance, toughness, and torsional strength.
Machining may be done by conventional means prior to heat treatment – after carburizing machining is usually limited to grinding. Value below normal HRC range, for comparison purposes only. AISI alloy steel is chromium, molybdenum, manganese containing low alloy steel. This alloy may be hardened by heating to F followed by a water quench. Can this material be used in design of Spur Gears? Posting Guidelines Promoting, selling, recruiting, coursework and thesis posting is forbidden.
However, the mechanical properties of this steel will be affected if it is welded in the heat treated condition, and post weld heat treatment should be performed. In this interview, AZoM talks to Dr. It can be formed using conventional techniques in the annealed condition. This case-hardening will result in good wear characteristics.
AISI 4140 Alloy Steel (UNS G41400)
AISI alloy steel has high ductility. The alloy may be welded by conventional methods, usually gas or arc welding. From Ducom 8 Nov Fahrenholtz about his research, and how he uses Phase Equilibrium Diagrams within it. Is there any reference that a is the replacement std instead of a Can any one help me RE: What types of steel could better than AISI against torsion fatigue and shear force?
Cancel reply to comment. Written by AZoM Sep 13 This alloy is typically used for carburized parts where a hardened case is desired for wear resistance. The alloy may be forged at F down to F prior to the hardening heat treatment or carburizing.
Do you think this is a good metal for this purpose?
