-
As a molybdenum-alloy steel plate for pressure vessels under the ASTM A204/A204M standard, A204 Gr.A is a low-alloy, high-strength material specifically designed for service conditions involving moderate temperatures (≤400°C) and moderate-to-high pressure2026-03-31
SB410 chemical composition, SB410 yield strength, SB410 tensile strength
SB410 steel plate under JIS G3103 standard which is used in pressure vessels, boilers and heat exchangers. The composition of SB410 steel makes it ideal for applications where elevated working temperatures are the norm and the material is used by fabricators throughout the oil, gas and petrochemical industry.
