A387 / SA387 Chrome Moly Steel
Boiler Plate Product Description
ASTM A387 vessel steel plate, also known as ASME SA387 pressure vessel plate material, A387/SA387 pressure vessel steel plate is the standard specification for chromium-molybdenum alloy steel pressure vessel plate. A387 / SA387 chromium-molybdenum alloy steel plate is mainly used for high-temperature welding boilers and vessel plates.
The steel plates supplied by GNEE Steel that comply with this standard include grade 1 and grade 2 boiler steel plates of ASTM A387 pressure vessel plate 5, 9, 11, 12, 22 and 91, which are used for high temperatures and corrosion and are widely used in steel boiler plates and pressure vessels. container.
A/SA387 GR 5 grade 2 pressure vessel plate
A high-quality chromium-molybdenum alloy steel plate specifically designed for use in carbon steel pressure vessels that are weldable at high temperatures. The added molybdenum gives the material higher temperature tensile strength, while the chromium improves corrosion resistance.
A/SA387 GR 9 grade 2 boiler steel
Weldable carbon steel plate for pressure vessels and boilers used at high temperatures. Adding chromium and molybdenum improves the corrosion and heat resistance of steel plates. A/SA387 Grade 9 steel plate is primarily used in the oil, gas and petrochemical industries.
A/SA387 GR 11 grade 2 pressure vessel quality steel
ASTM A387/ASME SA387 11 Grade 2 is a pressure vessel steel for high temperature service and is widely used in various industries, especially the oil, gas and petrochemical industries, since liquids and gases are usually stored at higher temperatures.
A/SA387 GR 12 grade 2 boiler grade plate
ASTM A387/ASME SA387 Grade 12 is a chromium-molybdenum carbon alloy steel used in weldable pressure vessels and industrial boilers in high temperature environments.
A/SA387 GR 22 grade 2 boiler quality steel
A/SA387 Grade 22 steel plate has good corrosion and oxidation resistance and is a good choice.
A/SA387 GR 91 grade 2 boiler quality plate
If high temperature resistance and good corrosion resistance are required, A/SA387 91 Grade 2 carbon alloy steel plate is a material worth considering. It is a pressure vessel grade of steel commonly used by manufacturers supplying the oil and gas industry.
