9CrMo
Description
Rod with 9% Cr-1% Mo for high-temperature service
Rod formulated for 9% Cr and 1% Mo alloy steels, ideal for applications in pressurized hydrogen in oil refineries subjected to prolonged service and high temperatures up to around 650 °C. Developed to ensure high toughness and improved corrosion resistance in the presence of superheated steam, hot hydrogen gas, and crude oil with a high sulfur content, surpassing the performance offered by 5% chromium and 0.5% molybdenum steels.
