Import Tips
• Provide heat treatment records showing normalized or annealed condition required for boiler service
• Confirm minimum wall thickness meets pressure vessel code requirements (ASME BPVC)
• Avoid common pitfall of declaring as 'alloy steel' - requires documented max 1.65% Mn and 0.6% other elements
