Stainless steels are high-alloy steels which have high corrosion resistance compared to other steels due to the presence of large amounts of chromium. Based on their crystalline structure, they are divided into three types such as ferritic, austenitic, and martensitic steels. Another group of stainless steels are precipitation-hardened steels. They are a combination of martensitic and austenitic steels.
Grade 440C stainless steel is a high carbon martensitic stainless steel. It has high strength, moderate corrosion resistance, and good hardness and wear resistance. Grade 440C is capable of attaining, after heat treatment, the highest strength, hardness and wear resistance of all the stainless alloys. Its very high carbon content is responsible for these characteristics, which make 440C particularly suited to such applications as ball bearings and valve parts.
Typical applications include:
UNS: ASTM/ASTE S44000
DIN: 1.4125
Good resistance to the atmosphere, fresh water, foods, alkalies and mild acids. Best resistance in the hardened and tempered and passivated condition. A smooth polished surface also assists.
The corrosion resistance of grade 440C approximates that of grade 304 in many environments.
Not recommended for use in temperatures above the relevant tempering temperature, because of reduction in mechanical properties by over-tempering.
In the annealed condition this grade is relatively easily machined; approximately the same as for high speed steel. Chips are tough and stringy so chip breakers are important. If these grades are hardened machining becomes more difficult and probably impossible.

Company Info:
退火 – 完全退火 – 850-900°C,缓慢炉冷至约 600°C,然后空冷.亚临界退火 - 735-785°C 和缓慢的炉冷.
硬化 – 加热至 1010-1065°C,然后在温油或空气中淬火.重型截面需要油淬.立即在 150-370°C 回火以获得各种硬度值和机械性能,如附表所示.
由于抗冲击性和耐腐蚀性降低,应避免在 425-565°C 范围内进行回火.在 590-675°C 范围内进行回火会导致硬度降低(产品变得可加工)和高抗冲击性.
如果需要焊接,请在 250°C 预热,并在焊接后进行完全退火.420 级填料会产生高硬度焊缝(虽然没有 440C 高),但 309 或 310 会产生具有更高延展性的软焊缝.
