725LN is an acid resistant austenitcferritic steel
We could delivery 725LN forging material as per the standard of A-182
We use EAF+VOD-ESR melting methods to melt the material of 725LN 
As per heat treatment of 725LN forged parts, it can be Solution annealing  950 - 10000 C. Holding time at solution annealing temperature approx. 30 min., followed by cooling in water.
The chemical composition of 725LN is as follows:

C	Si	Mn	P	S	Cr	Ni	Mo	N
≤0.020	≤0.4	1.7	≤0.015	≤0.010	25	22	2.1	0.12

The mechanical property of 725LN is as follows:

Tensile Strength	Min 127600 PSI	Min 880MPA
Yield Strength	Min 65250 PSI	MIN 450MPA
Elongation	Min 20%

725LN has better resistance to intercrystalline corrosion after sensitisation within
the temperature interval 500 – 9000 C
725LN  is not a ” stainless free cutting steel ” but a high class norm steel. It is an ” easy to machine steel”, considered for parts where extensive machining is required.
