Bring temperatures slowly up to F Cthen on to F Cafter working, furnace cool slowly to avoid cracking.
The number of and procedure for tension test for forgings depending on their weight are presented. The different solution heat treatment and annealing treatment received by the steel material are presented in details.
This is a high carbon martensitic stainless a4733 moderate corrosion asfm good strength and the ability to obtain and keep excellent hardness Rc 56 and wear resistance. The following bibliographic material is provided to assist you with your purchasing decision: The forgings shall be produced with prolongations for testing, unless otherwise specified.
Carbide or ceramic tooling is recommended.
Radical forming operations will result in cracking. Best machined in the annealed condition. Principal Design Features This is a high carbon martensitic stainless with moderate corrosion resistance good strength asrm the ability to obtain and keep excellent hardness Rc 56 and wear resistance.

Standard – Standard Specification for Stainless Steel Forgings ASTM A –
The forgings shall be produced with prolongations for testing, unless otherwise specified. This atm is not commonly welded due to its tendency to air harden.
Subscription pricing is determined by: If it must be welded, preheat to F C and post weld treat at F C for 6 hours followed by a slow furnace cooling to avoid cracking. This specification covers austenitic, austenitic-ferritic, ferritic, and martensitic atsm steel forgings for general use, and for low- or high-temperature service. A43 This alloy is not commonly welded due to its tendency to air harden.
Similar to machining some of the high carbon tool steel, this alloy has tough, stringy chip build-up.
