adtm The time to catch an obsolete specification is during contract review, astk there are commitmemnts to material and or sunk costs of material, production and inspection. Preheating at F is beneficial and subsequent heating after welding is recommended – consult the approved weld procedure for the method used. This alloy may be hardened by heating to F followed by a water quench. Carburize at to F in an appropriate carburizing medium and oil quench to harden.
Speaking of Precision Blog Sensemaking for the precision machining industry. Following carburizing of heavy sections a reheat at F will enhance both case and core properties of the alloy.
Hardening is done by oil quench from F. Not applicable to this alloy. Tempering of heat treated and water quenched parts not carburized is done at F to F with greater hardness the lower the tempering temperature. 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 astmm lesser extent in Flat Rolled Products, Tubular Products, Wire Products, Forging Products, and Casting Products.
This alloy is typically used for carburized parts where a hardened case is desired for wear resistance. By continuing to use this website, you agree to their use.

Consult the alloy supplier for aastm as to temperatures. A request for an assist always results in a prompt response from the appropriate supplier expert or an answer from PMPA Staff. Sign up for our Newsletter. Forming characteristics of alloy are good in the annealed condition.
ASTM A331 Rods for Construction, Length: 3 & 6 m
The alloy may be cold worked in the annealed condition a33 conventional methods. Machining is done prior to carburizing to within as close a tolerance as possible.
In the carburized condition this alloy is used for gears, ring gears, shafts and crankshafts. These specifications, standards and descriptions often specify mandatory product attributes. Cold working, as with machining, should zstm done to as close a tolerance as possible before heat treatment or carburizing. The alloy may be forged at F down to F prior to the hardening heat treatment or carburizing.
Where do you go for an assist when wierd, strange, and unusual specifications appear in a quote package? There were over 19, cancelled or superceded specifications, commercial item descriptions and standards when I first prepared my list of Obsolete Federal Specifications for cold finished steel in Create a free website or blog at WordPress. Improved carburized case and core properties can be obtained by furnace cooling from carburizing at – F and then reheating to F.
Machining may be done by conventional means astn to heat atsm – after carburizing machining is usually limited to grinding. AISI is a hardenable chromium, molybdenum, nickel low alloy steel often used for carburizing to develop a case-hardened part.
