* Annealed properties of cold finished bar, which pertain to Condition A of ASTM A276.
^# Tempering of grade 410 steels should be avoided at temperatures of 425-600 °C, owing to associated low impact resistance.

Possible Alternative Grades

The table below provides the suitable alternative grades to 410 stainless steels:

Table 5 - Possible alternative grades to 410 grade stainless steels

Grade	Reasons for choosing the grade
416	High machinability is required, and the lower corrosion resistance of 416 is acceptable.
420	A higher hardened strength or hardness than can be obtained from 410 is needed.
440C	A higher hardened strength or hardness than can be obtained even from 420 is needed.
