18MnMoNi5-5 機(jī)械性能

厚度 t mm	抗拉強(qiáng)度 σ_b Mpa	屈服點(diǎn) σ_s Mpa	斷后伸長(zhǎng)率或延伸率 δ %	沖擊吸收能量 KV2 J
t≤200	550~670	≥400	≥20	I：≥56，tr/t：≥40

① I = longitudinal to main forging directions；tr = transverse to main forging directions；t = tangential.
② Maximum room temperature for the impact test is 20 °C. By option, impact testing may be carried out at 0°C, with the condition to fulfil the impact values as stated in this table.
③ Until the yield point criteria are harmonized in the various national codes, determination of ReH may be replaced by determination of Rp0.2. In this case Rp0.2 values are 10 MPa lower for ReH values up to 355 MPa and 15 MPa lower for ReH values greater than 355 MPa.
