440C (UNS designation S44004) is a martensitic 400 series stainless steel, [1] and has the highest carbon content of the 400 stainless steel series. It can be heat treated to reach hardness of 58 to 60 HRC. It can be used to make rolling contact stainless bearings, e.g. ball bearings and roller bearings. It is also used to make knife blades.

AISI 440 has good oxidation resistance in intermittent use below 815 °C and continuous use up to 760 °C in air. SS440 heat treatment including annealing, quenching, tempering and stress relieving, etc. Subcritical annealing temperature range: 675-760 ℃ (1250-1400 ℉)

SUS440C とは、炭素の含有量が0.95〜1.20％と多く、焼入硬化性が特に高いマルテンサイト系ステンレス鋼の一種のことです（上図参照）。 焼き入れと焼き戻しによって、ステンレス鋼の中でも最高レベルのHRC58以上という硬度を出すことができます。 高硬度であるため、耐摩耗性や疲労強度が高く、引張強さも良好で、機械的性質に優れたステンレス鋼です。 価格は …
