50BV30

50BV30 wire is a cold heading steel wire rod. The chemical composition of 50BV30 wire is accurate and stable, ensuring the purity of the steel, making 50BV30 wire highly reliable and stable; it has a very small decarburization layer, is easy to spheroidize annealing, has a very low cold heading cracking rate, and has a uniform hardness distribution. It is a perfect combination of strength and toughness, and a symbol of reliability and durability. It provides convenience for subsequent cold heading processing, improves the product qualification rate, and strictly controls and improves product quality.
