UNS S31803 is chromium nickel molybdenum austenitic stainless steel
We could delivery UNS S31803 forging material as per the standard of A-182
We use EAF+VOD-ESR melting methods to melt the material of UNS S31803 
As per heat treatment of UNS S31803 forged parts, it can be solution annealed at 1020-1100ºC, water quench.
The Chemical Composition of UNS S31803  is as follows:

Chemical Composition Limits
Weight%	C	Mn	P	S	Si	Cr	Ni	Mo	N
UNS S31803	0.03 max	2.0 max	0.03 max	0.02 max	1 max	21-23	4.5-6.5	2.5-3.5	0.80-0.20

The mechanical property of UNS S31803 is as follows:
 

Alloy	Tensile Strength N/mm²	Proof Strength 0.2% N/mm²	Elongation (%)	Hardness Brinell
F51	105	55	35	170-255

UNS S31803 is resistant to intergranular corrosion. It has better corrosion resistance than that of other austenitic stainless grades such as 316, with higher resistance to stress corrosion cracking to that of either 304 or 316 stainless grades
UNS S31803 is requires an adjustment of tooling data and machining method, in order to achieve satisfactory results. Compared to Sanmac 316/316L, the cutting speed must be reduced by approximately 50-55% when turning UNS S31803 with coated, cemented carbide tools. Much the same applies to other operations. Feeds should only be reduced slightly and with care
