Product Overview
16Mo3 / A387 Gr12 CL1/CL2 Steel Plate (16Mo3 1.5415) is molybdenum low alloy heat resistant pressure vessel steel plate, widely used in high temperature and medium pressure working conditions. It is manufactured per GB/T713, ASTM A387, EN 10028-2 standards.
This grade contains molybdenum element to strengthen matrix and improve high temperature lasting strength. It can maintain stable mechanical property under continuous high temperature service, with good toughness and weldability.
Available thickness from 6mm to 250mm, width range 1500–4100mm, standard length 6–12m. We can provide custom cut-to-size plates and irregular blanking. It is commonly used for boiler drums, heat exchanger, petrochemical reactor, oil refinery and hydrogenation equipment. Material MTC and third-party inspection reports can be supplied before shipment.
