The introduction of advanced high-strength steel (AHSS) has undeniably marked a turning point in the field of steel processing through its exceptional qualities and adaptability. In this article, we will explore the boundless possibilities of advanced high-strength steel processing. You will also discover why Kenwal, an expert in AHSS and a reputable steel processor, is the trusted choice for all your AHSS needs.


What Is Advanced High-Strength Steel (AHSS)? 


Compared to traditional steel, advanced high-strength steel is a cutting-edge steel variant that represents the future of steel processing. Celebrated as the strongest steel available, AHSS exhibits unparalleled mechanical properties, boasting exceptional strength, malleability, and deformation resistance.

The advantages of AHSS are achieved through the integration of various steel alloys and the optimization of its microstructure. Advanced high-strength steel, in more precise terms, includes all martensitic and multiphase steels with a minimum specified tensile strength of at least 550 megapascal pressure units (MPa). This sets it apart from conventional high-strength, low-alloy HSLA steels, which typically feature a single-phase ferritic structure, occasionally accompanied by pearlite in carbon-manganese (C-Mn) steels.

In contrast, AHSS primarily consists of steels with a complex multiphase microstructure, incorporating one or more phases beyond the typical ferrite, pearlite, or cementite composition. These additional phases, such as martensite, bainite, austenite, and/or retained austenite, are present in quantities significant enough to impart distinct mechanical properties.
At Kenwal, we offer processing for different types of advanced high-strength steel, including dual-phase (DP) steel, transformation-induced plasticity (TRIP) steel, and martensitic steel, just to name a few. Our expertise and state-of-the-art processes ensure that the full potential of AHSS is harnessed, delivering lighter, stronger, and more sustainable solutions across various industries.

Unlike conventional steels, certain varieties of AHSS exhibit a remarkable balance between strength and ductility due to an enhanced capacity for strain hardening. Meanwhile, other types of AHSS boast ultra-high yield and tensile strengths, along with bake-hardening behaviors. These differing types of advanced high-strength steels can be identified as either first, second, or third generation, each categorized by the differences of their microstructural components.

Benefits of Advanced High-Strength Steel


  • Superior strength-to-weight ratio:

    AHSS provides increased strength while maintaining a lower weight profile, making it a go-to steel grade for certain industries, especially automotive.

  • Environment-friendly:

    The reduced energy demands of advanced high-strength steel make it an eco-friendly choice, leading to improved fuel efficiency and a substantial decrease in greenhouse gas emissions.

  • Formability and adaptability:

    AHSS retains outstanding formability, allowing for the creation of intricate shapes and designs. This flexibility adheres to a wide range of steel products across many industries.

  • Cost-efficiency:

    Its diminished energy and material requirements not only promote environmental benefits but also translate into significant cost savings during both production and transportation.

Advanced High-Strength Steel Applications


Although AHSS has a long history of use in the automotive industry, it is also finding broader applications in numerous other industries. This superior class of steel has demonstrated the ability to enhance engine performance and raise speed limits in aircraft, ships, and trains. For instance, AHHS’s crash safety perks result in a material that is well suited for rail transportation systems. Oil rigs, bridge construction, civil engineering, and construction machines are also absorbing the benefits of AHSS processing.

In the near future, as manufacturing methods progress and become more efficient, the AHSS market will lead to substantial energy savings for manufacturers worldwide.


The Promising Future of AHSS Processing


According to Market Research Reports, the global automotive AHSS market size is projected to grow from where it was in 2022 at US$16890 million to US$25600 million in 2029. Trends such as the introduction of pre-oxidation for galvanizing AHSS, as well as the development of third generation AHSS, have sparked a growing interest in the production and utilization of AHSS throughout industries.


As our steel processing experts at Kenwal look ahead to the future of AHSS, it’s clear that the steel processing industry will increasingly rely on this material. Its applications extend far beyond conventional steel, with potential uses across various industries thanks to the steel’s light weight, strength, durability, recyclability, versatility, and high corrosion resistance.
