low alloy steel Product Introduction
ASTM A387 Specification is the standard specification for pressure vessel plate, alloy steel, chromium-molybdenum plate for use in high temperature welded boilers and pressure vessels. ASME SA387 standard covers the supply of weldable chromium-molybdenum alloy steel plates for pressure vessels used in high-temperature service.
ASME SA387 alloy steel is a high-quality chromium-molybdenum alloy steel plate designed for use in high-temperature weldable carbon steel pressure vessels. The added molybdenum gives the material higher temperature tensile strength, while the chromium improves corrosion resistance.
