Frequently Asked Questions
The main difference is in yield strength and hardness. Grade 700L offers higher tensile strength and hardness than 510L, making it suited to automobile beams requiring greater load-bearing performance. Grade 510L provides a balance of strength and plasticity.
The listed standards include ASTM A572/A572M, JIS G3106, and GB/T standards such as GB/T 714 and GB/T 19879. These standards support compatibility with international engineering projects.
Yes. Deep processing options include laser, plasma, and flame cutting, along with hot-dip galvanizing and color coating to meet project and environmental requirements.
Each batch undergoes visual inspection, dimensional measurement, and metallographic examination. These checks help verify that the internal structure and chemical composition meet the required specifications.
Common sizes are held in long-term inventory to support fast delivery. The lead time for a specific order depends on processing requirements and order volume.
Carbon content influences steel hardness and strength: higher carbon levels generally increase both, while typically reducing plasticity. The 510L and 700L grades are engineered to balance these properties.
