HRFⓇ Bolt (Hiten Refining Bolt) has 1400MPa strength by quenching and tempering processes. Bolt strength is higher compared to other bolts in the current market. Also, HRFⓇ bolts reduce the risk of delay fractures, and are less likely to lose bolt strength in high temperature environments.
By using HRFⓇ, size and weight reductions are possible without losing bolt strength. This bolt application can be used in a high-temperature environment, replacing a stainless steel bolt.
Apply where weight and cost reduction are beneficial E.g. Performs well in areas requiring reliability such as the engine and in a high temperature environment.
