testing method for secondary embrittlement
The steel industry is evolving at a breathtaking pace, and Baowu Group—through its flagship Baosteel—is once again at the forefront of groundbreaking advancements. This year has already seen significant strides in standardizing safety and performance metrics, with over 90 new national steel standards released in 2025 alone. Among these, innovations in wear-resistant and high-strength steels for construction machinery, mining equipment, and semi-trailers are poised to reshape the landscape. But one achievement stands out: the global recognition of China’s proprietary testing method for secondary embrittlement—a critical issue in high-strength steel applications.
Secondary embrittlement refers to the loss of toughness in metal sheets after processes like stamping or forming, which can lead to sudden fractures in low-temperature environments. For years, the lack of a unified global standard made it challenging to ensure consistency in material selection and safety protocols. Baosteel’s solution—originally developed as GB/T 24173—integrates cupping formation and drop-weight impact testing to accurately measure this risk. This method, now advancing as an ISO standard (ISO/AWI 24270), provides a reproducible framework to evaluate materials like advanced high-strength steels and batteries, ensuring end-products withstand real-world stresses.
The latest standards unveiled in 2025 highlight Baowu’s broader push toward durability and sustainability:
These advancements aren’t just technical wins; they build trust by giving clients measurable benchmarks for reliability. For example, Baosteel’s data-driven approach to secondary embrittlement has already been adopted by automotive giants to validate material safety.
As we witness China’s steel expertise evolve from producing high-quality products to setting global benchmarks, it’s clear that collaboration drives progress.
