It has combined properties of heat resistance, corrosion resistance, wear resistance, and high-temperature oxidation resistance, contributing to total cost reduction.
This product is particularly used for billet top rollers (foot rollers) and has a proven track record. "Silicoroy A2" is an all-round type of stainless steel that contains approximately 3.5% high silicon in its chemical composition. Silicon contributes to properties such as heat resistance, oxidation resistance, hardness, strength, and corrosion resistance. Due to the approximately 3.5% Si content, it is relatively strong against high-temperature oxidation. 【Features】 ■ Heat resistance ■ Corrosion resistance: Relatively high corrosion resistance against water and strongly acidic powders ■ Fracture toughness (heat check resistance): Minimal occurrence of heat cracks during repeated high temperature to rapid cooling, excellent resistance to crack propagation ■ High-temperature corrosion wear resistance: Superior overall performance contributes to the longevity of the rollers *For more details, please refer to the PDF document or feel free to contact us.

Company information
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.
