Abstract

The invention discloses a marine double block. The marine double block comprises axles made from an alloy material subjected to tempering treatment. The alloy material is composed of 1%-2% of Si, 1.2% of At, 0.9% of Ru, 0.4% of Rh, 0.8% of Pd, 0.8% of Ag, and the balance Fe and unavoidable impurities. The tempering treatment of the alloy material is conducted in the following steps that (1) first tempering is conducted at 435 DEG C, the tempering time is 5.5 hours, and then the temperature of the alloy material is decreased to the room temperature in an air cooling mode; (2) second tempering is conducted at 485 DEG C, the tempering time is 4.5 hours, and then the temperature of the alloy material is decreased to the room temperature in an air cooling mode; and (3) third tempering is conducted at 535 DEG C, the tempering time is 3.5 hours, and then the temperature of the alloy material is decreased to the room temperature in an air cooling mode. The axles used for the marine double block are small in weight, high in strength, good in resistance to abrasion, corrosion, heat, cold, oxidation and weather resistance and long in service life.
