Axia for Marine Applications: High Durability Precipitation Hardening Stainless Steel

Withstand harsh marine environments! High hardness, high corrosion resistance, and high strength precipitation hardening stainless steel "Axia".

In marine applications, materials that are resistant to corrosion and wear, and can maintain performance over long periods, are essential. Particularly in the use of seawater, salt, and harsh environments, high durability is required. Conventional stainless steel has faced challenges in balancing strength and corrosion resistance. Axia achieves both high hardness and high corrosion resistance, contributing to the longevity of components in marine environments. 【Application Scenes】 - Marine structures - Ship parts - Undersea cables - Marine plants 【Effects of Implementation】 - Increased longevity due to high corrosion resistance - Improved reliability due to high strength - Reduction in total costs - Decreased maintenance frequency

Silicolloy is a revolutionary new material that contains a large amount of silicon (silicon) and was developed using pure domestic technology. Silicolloy is a super alloy that possesses high strength, heat resistance (high-temperature oxidation resistance), corrosion resistance, wear resistance, high hardness, and low dimensional changes during heat treatment, all in one steel. Currently, many engineers (technicians and designers) are advancing its commercialization, contributing to new product development and total cost reduction through extended product lifespan. There are 'Silicolloy A2', which excels in overall balance as a precipitation-hardened stainless steel, and 'Silicolloy XVI', which has the highest hardness in the world as a precipitation-hardened type. Those who require both corrosion resistance and high hardness should definitely take note! In 2025, a new material called 'Axia Zero Series' will be developed. This new material is a precipitation-hardened stainless steel that not only has high corrosion resistance and high hardness but also high strength and high durability. 'Axia Zero3' achieves high hardness of 56-58 HRC, high corrosion resistance equivalent to austenitic types, and high strength in the 2000 MPa range. It features hardness obtained through precipitation hardening treatment at 480°C, which minimizes deformation and dimensional changes due to heat treatment and resolves various issues related to quenching.
