Performance Comparison and Selection Guide for LR AH32/DH32/EH32 Marine Steel Plates

The basic strength parameters of LR Grades AH32, DH32, and EH32 are consistent, but they exhibit gradual differences in low-temperature impact toughness, manufacturing process control, impurity content limits, and applicable ambient temperatures. This article systematically compares the key differences among these three grades in terms of technical specifications and application scenarios, and provides recommendations for selecting the appropriate grade based on project requirements.
