Factory Direct Sales Gost 30x Steel High Hardenability Characteristics - China
price: 503.00 Dollar US$
GOST 30X steel surpasses all others in terms of hardenability.
Hardenability refers to the ability of steel to achieve a martensitic structure during quenching, and it directly impacts the performance and usability of steel components.
GOST 30X steel, due to its moderate content of alloying elements such as chromium, significantly enhances its hardenability.
In oil, the critical hardenability of GOST 30X steel reaches 8-34mm, while in water, it reaches 19-56mm.
In comparison, the hardenability of No.
30 steel is much lower, reaching only 1-3mm in oil and 6-12mm in water.
This means that parts manufactured using GOST 30X steel achieve a deeper hardened layer after quenching, resulting in excellent overall performance from the surface to the interior.
This significantly improves wear resistance and fatigue strength, enabling stable operation in harsh operating environments.
