摘要

0Cr16Ni5Mo钢由6 t真空感应炉+电渣重熔工艺冶炼

并锻造成Φ120~160 mm钢材

终锻温度≥900℃

力学性能试样经950℃ 1 h空冷+520℃ 4 h回火处理。对该钢47炉次的棒材回归分析

得到了0Cr16Ni5Mo钢材成分与力学性能的定量回归关系式：σ

Abstract

The test steel 0Cr16Ni5Mo is melted by a 6 t vacuum induction furnace + electro-slag remelting process

forged to Φ120-160 mm steel products

finishing forging at ≥ 900 ℃

and the samples for mechanical properties test are treated at 950 ℃ for 1 h

air cooling + tempered at 520 ℃ for 4 h air cooling. The quantity regression relationships between composition and mechanical properties of products of steel 0Cr16Ni5Mo are obtained by regression analysis on steel products of 47 heats that are(σ
