Which is the best way to nitride 4340 alloy steel?
Hardened and tempered 4340 alloy steel can also be nitrided, giving a surface hardness of up to Rc 60. Heat to 500°C 530°C and hold for sufficient time (from 10 to 60 hours) to develop the depth of case. Nitriding should be followed by slow cooling (no quench) reducing the problem of distortion.See all results for this questionWhat kind of steel is SAE 4340 made of?4340 Chemical Composition, % ASTM Notes ASTM A29/A29M Steel Bars, Carbon and Alloy, Hot-Wrough astm a 434 Cutting ASTM A322 Steel Bars, Alloy, Standard Grades ASTM A519/A519M Seamless Carbon and Alloy Steel Mechanic astm a 434 Cutting ASTM A646/A646M Premium Quality Alloy Steel Blooms and B astm a 434 Cutting See all results for this questionWhat is the ASTM AISI 4340 steel equivalent to?ASTM AISI 4340 steel equivalent to SAE, European (German DIN, British BSI, France NF), Japanese JIS and Chinese GB standard (for reference).See all results for this question
