Chemical Composition:

Grade	C	Mn	P	S	Si	Cr	Ni	V	Mo
1.7707	0.26- 0.34	0.40- 0.70	0.035 max	0.035 max	0.40  max	2.30- 2.70	0.60 max	0.10- 0.20	0.15- 0.25

Heat Treatment:

Soft Annealing: Heat to 680-720ºC, cool slowly. This will produce a maximum Brinell hardness of 248.
 
Nitriding:
Gas/plasma nitriding temperature (gas, salt bath): 570-580ºC
Gas/plasma nitriding temperature (powder, plasma): 580ºC
Surface hardness after nitriding: 800 HV
 
Hardening: Harden from a temperature of 850-880ºC followed by oil quenching.
 
Tempering:Tempering temperature: 570-680ºC.
 
 

Application:
Structural parts of medium and large cross sections and high surface hardness, e.g., valve and gate valves, cylinders for combustion engines, superheated steam valves and fittings.
