What is the proportion of high-strength steel in Geely Emgrand?
2 Answers
Emgrand adopts a cage-type safety body with over 59% high-strength steel content. While enhancing overall strength to ensure ample space, it also incorporates Geely's unique, industry-leading "Safety Identification Circle", making it the most outstanding model in terms of safety coefficient within its class and even surpassing higher-class products. Definition of high-strength steel: It varies according to the degree of technological advancement required by the era. Generally speaking, alloy steel with a yield strength above 1370MPa (140kgf/mm) and tensile strength above 1620MPa (165kgf/mm) is called ultra-high-strength steel. Standards for high-strength steel: There are numerous international standards for high-strength steel, with just unified international standards including both "ISO" and "CEN". Almost every major steel-producing country has its own national standards.
I recently test drove the Geely Emgrand, and the salesperson mentioned that over 70% of the body is made of high-strength steel. This ratio is quite high among domestic A-segment cars, especially with key areas like the door frames and chassis using 1500 MPa hot-formed steel, matching Volvo's safety standards. A friend of mine was rear-ended while driving an Emgrand—the trunk was deformed but the passenger compartment remained intact, which really highlights the quality of the steel used. During normal driving, the body feels incredibly solid, with no creaking sounds when cornering, and it stays stable even when overtaking large trucks on the highway.
