In the triangular competition of lightweighting, high safety and low cost in the automotive industry, advanced high-strength steel has always been the absolute core of the body-in-white material system. From the easily formable outer covering parts to the anti-collision safety structural components, from cold-formed low-carbon steel to 1800MPa grade hot-formed boron steel, the microstructure characteristics, mechanical performance, process windows and applicable scenarios of different steel types vary greatly, directly determining the cost, weight and safety performance of the vehicle body.

High-Strength Interstitial-Free (HS-IF) steel is currently the most widely used advanced high-strength steel grade for automotive bodies, accounting for 30%~40% of the total steel consumption of a vehicle body. It achieves an optimal balance between deep drawability and mechanical strength, making it the primary lightweight material for outer panels and structural components. Data Sources: GB/T 20564.3-2017, Baosteel Standards Q/BQB 413-2009 & Q/BQB 420-2018, Technical Guidelines for Application of Automotive Steel published by China Society of Automotive Engineers (CSAE)

In the vehicle development system, steel sheets serve as the core material for body-in-white and chassis components. From complex-shaped outer body panels and impact-resistant structural reinforcements to load-bearing core parts of chassis and wheels, four major steel categories form the backbone of automotive steel materials: cold-rolled low-carbon steel, low-alloy high-strength steel, and hot-rolled structural steel.

Driven by the dual demands of automotive lightweighting and crash safety, Advanced High-Strength Steel (AHSS) has become the predominant material for vehicle bodies. This article systematically analyzes three widely used core steel grades in the automotive industry: QP steel, a representative of the 3rd-generation AHSS; DH steel, an upgraded version of conventional DP steel; and SAPH hot rolled steel, the mainstream basic grade. All data are sourced from official standards of Baosteel and ArcelorMittal, as well as practical application cases of mass-produced vehicles, serving as reliable references for engineering design and CAE simulation.

Dual-phase(DP) Steel, as the representative of the first generation of Advanced High-Strength Steel(AHSS), features three core properties: low yield-to-strength ratio, high work hardening rate and excellent crash energy absorption. It has perfectly resolved the eternal contradiction between lightweighting and safety in the automotive industry. Currently, DP steel accounts for over 90% of the advanced high-strength steel(AHSS) used in vehicle body-in- white, and is the preferred material for new energy vehicle（NEV） battery packs, body structural components and safety components.

In September 2019, we visited the largest stamping G-TEM plant in the UK and established a long-term partnership for the supply of steel raw materials. Later, we expanded our cooperation to cover aluminum raw materials as well.
