The mechanical property of UNS S21900 is as follows
 

Alloy	Cross Section Size	Test Direction	Yield Strength 0.2%		Ultimate Tensile Strength		Elongation in 2"(%)	Reduction of Area %	Rockwell B Hardness
			ksi	MPa	ksi	MPa
UNS S21900 (21-6-9)	6" (152mm) sq	Longitudinal	62	428	95	655	46	69

UNS S21900 should be stress-relieved at temperatures below 705°C (1300°F). However, stress relieving of this steel below (900 to 1250°F) would affect the mechanical properties of the steel.
UNS S21900 is difficult to machine due to its high work hardening rate. Hence, ample cutting fluids, positive feeds and slow speeds are preferred to overcome work hardening
