2024年12月5日 · When comparing the mechanical properties of A395 and A216, A395 ductile iron exhibits higher ductility and better wear and impact resistance compared to A216 carbon steel. A395 has a tensile strength ranging from 60,000 to 100,000 psi and a yield strength of at least 40,000 psi, with elongation at break between 18% and 30%.

2019年1月3日 · Scope1.1 This specif i cation covers ductile iron castings forpressure-retaining parts for use at elevated temperatures. Cast-ings of all grades are suitable for use up to 450 °F.

A395 是球墨铸件，其综合性能接近于钢，正是基于其优异的性能，已成功地用于铸造一些受力复杂，强度、韧性、耐磨性要求较高的零件。 球墨铸铁 已迅速发展为仅次于灰铸铁的、应用十分广泛的铸铁材料。 A‍395是含碳量大于2.11%的 铁碳合金，由工业生铁、废钢等钢铁及其 合金材料 经过高温熔融和铸造成型而得到，除Fe外，还含及其它铸铁中的碳以石墨形态析出，若析出的石墨呈条片状时的铸铁叫灰口铸铁或灰铸铁、呈蠕虫状时的铸铁叫蠕墨铸铁、呈团絮状时的铸铁叫白 …
