Environmental Cracking Behavior of Submerged Arc-Welded Supermartensitic Stainless Steel Weldments

摘要

Supermartensitic stainless steel welds produced by submerged arc welding were assessed for their micro-structure and properties. Slow strain rate tests conducted on these specimens revealed that both the parent material and the weld metals are susceptible to cracking under conditions of hydrogen (H) charging.
