AISI 631 is A precipitation hardenable chromium-nickel-aluminum stainless steel combining high strength, moderate corrosion resistance and properties well suited for flat springs.
We could delivery AISI 631 forging material as per the standard of ASTM B564
We use EAF+VOD-ESR melting methods to melt the material of AISI 631
The chemical composition of AISI 631 is as follows:

Chemical Composition Limits
Weight%	C	Mn	Si	P	S	Cr	Ni	Al
AISI 631	0.09 max	1.00 max	1.00 max	0.040 max	0.030 max	16.00-18.00	6.50-7.75	0.75-1.50

 
As per heat treatment of AISI 631 forged parts, We could do solution treatment and ageing treatment together.                                                                                   We could do Heat treatment of AISI 631 forging parts as follows:H900,H925,H1025,H1075,H1100,H1150 and so on.
The mechanical property of AISI 631 is as follows:

Alloy	Form Available	Temper	Specifications	Tensile Min.*	Yield Min.*	Elongation Min.*
AISI 631	Coil or Sheet	Annealed	AMS 5528 ASTM A693	150,000 MAX	65,000 MAX	20 %
	Coil or  Sheet	Condition C	AMS 5529 ASTM A693	200,000	175,000	1 %

 
As per machining of AISI 631 material, It is smilar with stainless grades 302, 303,410,420,430,430F and so on.But it have high strength comparing above material. For H900 condition of AISI 631 material, it will have high hardness and strength and very hard to turning, CNC machined, Drilling and so on
