15CrMoR Alloy Steel Plate GB/T 713 Hot Rolled Cr-Mo Pressure Vessel Boiler Steel 6-200mm

15CrMoR Alloy Steel Plate

15CrMoR is a chromium-molybdenum (Cr‑Mo) low alloy heat‑resistant steel plate produced under the Chinese standard GB/T 713, purpose‑built for pressure vessels and boilers in elevated‑temperature service. Its equivalent grades include ASTM A387 Gr.12 and EN 10028‑2 13CrMo4‑5. The plate is supplied in normalized and tempered (N+T) condition so that a stable microstructure and reliable mechanical performance are achieved before fabrication.

Key Features

• Normalized + tempered heat treatment for stable strength and toughness
• Excellent high‑temperature strength and creep resistance, service temperature up to 550°C
• Good weldability, forming and machining performance
• Strict chemical composition control and ultrasonic testing (UT) available on request
• MTC to EN 10204 3.1 supplied before shipment
