摘要

系统探讨了S32750超级双相不锈钢压力容器封头的成形工艺。通过对S32750超级双相不锈钢的化学成分、金相组织、力学性能和耐腐蚀性能的分析，确定了该材料具有高强度、良好的焊接性能和耐腐蚀性能。基于材料特性和相关标准规定，制定封头的成形工艺，采用两步法成形：冷冲压预成形和热冲压终成形。成形过程的关键控制点包括原材料验收、划线下料、边缘准备、冷热冲压成形、恢复性能热处理等。成形后，对封头的形状尺寸、厚度、硬度及铁素体含量等进行检测，验证了成形工艺的有效性。在封头母材上进行拉伸、冲击、晶间腐蚀等试验，结果表明封头的力学性能和耐腐蚀性能得到了良好恢复。

Abstract

This paper systematically discusses the forming process of S32750 super duplex stainless steel pressure vessel heads. Through the analysis of the chemical composition

microstructure

mechanical properties

and corrosion resistance of S32750 super duplex stainless steel

it is determined that the material has high strength

good weldability

and corrosion resistance. Based on the material properties and relevant standards

a two-step forming process is formulated

including cold stamping pre-forming and hot stamping final forming. Key control points of the forming process include raw material inspection

marking and blanking

edge preparation

cold and hot stamping forming

and heat treatment for recovery of material properties. After forming

the shape and size

thickness

hardness

and ferrite content of the head are inspected to verify the effectiveness of the forming process. Tensile

impact

and intergranular corrosion tests on the head blank material show that the mechanical properties and corrosion resistance of the head have been well restored. The effectiveness of the S32750 super duplex stainless steel head forming process is summarized

providing experience for the manufacture of duplex stainless steel pressure vessels.
