BSF
1 / 5
Maintains high strength even below -60℃, preventing brittle fracture. Suitable for liquefied natural gas pumps and liquid nitrogen pumps.
Carbon steel or alloy steel (35CrMoA/42CrMoA) with body-centered cubic crystal structure can have hardness and impact performance optimized through tempering heat treatment.
For A-286 stainless steel screws at -275℉ (-170℃), thermal contraction increases thread friction and improves locking performance.
Glass fiber/epoxy resin composite joints show 15% higher load-bearing capacity at -40℃ vs. room temperature, with more significant pre-tightening torque effect.
Stainless steel fasteners (per ISO 3506-1 standard) possess both corrosion resistance and mechanical properties in low-temperature environments.
Wind turbine bolts (10.9/12.9 grade) withstand multi-axis stress and dynamic loads while avoiding brittle fracture at low temperatures.
The low-friction coefficient design facilitates installation and disassembly in low-temperature environments, reducing operational complexity and maintenance time.
