ZJSB whole spiral stabilizer adopts high–quality chrome molybdenum alloy steel production (except non–magnetic), and is up to prospective hardness, strength, and shock resistance through special heat treatment technology. Stabilizer thread is made according to API, whole wearing belt adopts studded columnar tungsten carbide hard alloy or other wearing material or the purpose of protecting the body. Non–magnetic stabilizer uses studded hard alloy after demagnetization. ZJSB whole spiral stabilizer is subject to SY 5051–91 standard. adopts high–quality chrome molybdenum alloy steel production (except non–magnetic), and is up to prospective hardness, strength, and shock resistance through special heat treatment technology.
