Carbon Steel Seamless Pipe For Automobile Half-Axle Sleeve
Product Description: The seamless steel pipe for automobile half-shaft casing is mainly used to protect the transmission shaft. The two ends of the half-shaft casing are fixed on the bracket, and the transmission shaft passes through the half-shaft casing to protect the transmission shaft. According to domestic market surveys, the annual consumption of half-shaft sleeves in the national automobile industry is about 15,000 tons. With the further development of the automobile industry, the market demand for half-shaft sleeves has great growth potential. The main materials for automobile half-shaft casing are 45#, 45Mn2, 40MnB, 40Cr, 25MnCr, and the product standard is YB/T5035-1996.
