Steel is one of the most critical materials in the automotive industry. A typical vehicle uses about 900 kg of steel across its body, drivetrain, suspension, and safety systems. Its role is present in almost every part of the vehicle.
India’s automotive sector is changing fast. The growth of electric vehicles, stricter BNVSAP safety norms, and a push for lightweighting have increased demand for advanced steel grades. Indian mills are expanding capacity under the PLI scheme and investing in green-steel technologies to meet these needs.
Different vehicle parts require different steel grades, depending on strength, formability, and safety requirements. This article outlines the main types of steel used in today’s automotive industry and their relevance to India’s evolving market.
Key features of steel in the automotive industry
Steel offers a mix of strength, durability, cost-efficiency, and sustainability that few materials can match. These qualities make it essential for India’s fast-growing automotive sector, especially as safety norms tighten and EV production expands.
Strength and crash performance
Modern vehicles rely on advanced high-strength steel, ultra-high-strength steel, and press-hardening steel. These grades offer high tensile strength and better energy absorption during a crash. They also help manufacturers improve BNVSAP and GNCAP safety ratings.
Lightweighting
Third-generation AHSS and martensitic steel allow thinner, lighter parts without losing strength. This supports fuel efficiency in ICE vehicles and helps offset battery weight in EVs. Indian mills such as Tata Steel, JSW, and AM/NS now supply several of these grades locally.
Formability and design flexibility
High-formability steel enables complex shapes needed in modern body-in-white designs. This is important for both structural parts and EV battery enclosures, where precision and stiffness matter.
Cost efficiency and localisation
Steel remains more cost-effective than aluminium or composites. India’s expanded automotive-grade CR and coated-steel capacity reduces import dependence and strengthens supply security for OEMs and tier-1 suppliers.
Corrosion resistance and coatings
Galvanised and galvannealed coatings protect parts exposed to weather or battery-pack heat cycles. These coatings are crucial for long-term durability and NVH performance.
Recyclability
Steel is fully recyclable, supporting India’s push towards greener automotive manufacturing and the Government’s decarbonisation commitments.
Overall, ongoing innovation in India’s steel sector, supported by PLI incentives and green-steel investments, has made advanced automotive steel more accessible to domestic manufacturers.
Steel in vehicle structures
Steel remains the core material for most vehicle frames in India, from two-wheelers to passenger cars and large commercial vehicles. Requirements vary by segment, but strength, safety, and cost efficiency remain the key drivers.
Passenger cars
Modern passenger cars use a mix of advanced high-strength steel, ultra-high-strength steel, and press-hardened parts. These grades improve crash performance and support BNVSAP and GNCAP ratings. Many Indian OEMs now use tailor welded blanks and hot-stamped components in the body-in-white to save weight and increase stiffness.
Most car bodies need a minimum tensile strength of around 440 MPa. AHSS easily meets this, while also helping with lightweighting and fuel efficiency. This balance of safety and cost makes steel the preferred choice over aluminium for most mass-market cars in India.
Electric vehicles
EVs place new demands on structural steel. High-strength grades are used to protect the battery pack, support the skateboard platform, and reinforce the underbody. Thermal management and corrosion resistance are especially important. Indian mills now supply coated automotive steel suitable for EV battery enclosures and motor components.
Motorcycles
Motorcycle frames must support the engine, fuel tank, suspension, and rider weight. Steel provides the necessary strength while allowing curved and complex shapes at a competitive cost. Coated steel helps prevent corrosion. Alternatives such as carbon fibre exist but are far more expensive, making steel the dominant material for India’s two-wheeler market.
Buses and commercial vehicles
Large vehicles rely on strong, rigid frames that can handle heavy loads and long operating cycles. AHSS and high-formability steels offer the right mix of strength, durability, and safety. Their use also supports lightweighting, which helps reduce operating costs for fleet owners.
