A387 is an alloy pressure vessel steel under ASTM, used in high-temperature environments. The A stands for Alloy, and 387 refers to its specification. It offers a good balance of strength and heat resistance, suitable for boilers and pressure vessels, with excellent weldability and corrosion resistance.
Описание
What is A387？
A387 is a solid alloy steel made of chromium (1%-2.5%) and molybdenum (0.5%-1%). It is processed through hot rolling. This steel offers excellent strength and resistance to high temperatures and corrosion, making it ideal for pressure vessels and boilers in industries like power generation and petrochemicals. Subcategories include ASTM A387 Grades 2, 12, 11, 22, 22L, 21, 21L, 5, 9, and 91. All other grades come in two tensile strength levels except for Grades 21L, 22L, and 91.Why Choose A387 ALloy Pressure Vessel Steel?
Are you looking for steel that performs well in high-temperature pressure vessels? We recommend A387 alloy pressure vessel steel. It’s ideal for industries like power generation and petrochemicals due to its excellent heat and corrosion resistance. Choosing A387 means reliable, easy-to-weld steel that reduces long-term maintenance, giving you both safety and cost benefits. A387 outperforms other steels with its high strength and flexibility in extreme environments, especially where heat stability is crucial. For similar high-temperature demands, alternatives like A335, 12Cr1MoV, or P91 are also suitable for specific conditions.Спецификация продукта
