13MnNiMoR-Z15 is a steel plate for pressure vessels. 13MnNiMoR-Z15 steel plate can be delivered in normalized + tempered state. (It can also be negotiated according to customer requirements, and the specific delivery conditions are reflected in the contract.) 13MnNiMoR-Z15 vessel plate is often used in medium and low temperature environments as a common raw material for boiler and pressure vessel manufacturing.
Tensile yield strength of 13MnNiMoR-Z15 vessel plate:
Tensile strength: 570--720Mpa, Yield strength: 390Mpa, Elongation: 18%, Impact energy: 41J
Tempering temperature of 13MnNiMoR-Z15 steel plate:
The tempering temperature of 13MnNiMoR-Z15 vessel plate should not be lower than 650 degrees. The old grades 13MnNiCrNbG and 13MnNiMoNbR are no longer used. Additional flaw detection requirements and Z15-Z35 tear resistant (thickness direction performance) steel plates can be produced. Z-direction performance steel plates can also be provided according to ASTM, A770 and other standards.
