AISI H13 Mandrel Bar For Seamless Steel Pipe
AISI H13 Mandrel bar is very long round rod and plays a crucial role in producing large diameter seamless pipes in modern industries, especially one of the key pieces of tooling required during the production of Seamless Tubes and Pipes. Once the billet has been pierced, the Mandrel Bar supports the tube shell internally during elongation and wall thickness reduction.
During producing, Mandrel Bars have to bear strong and complicate stretch, compressing touching stress and high temperature cold-hot yield stress under high speed cycling. Under these circumstance, chemical components, mechanical propertied, no-metallic inclusion, grain size, microstructure, ultrasonic test, size precision, surface finish, all these factories of steel are required very strictly.
Our Mandrel bar is made from H13(4Cr5MoSiV1) and we are able to deliver mandrel bars of up to 25 m in length and up to 800 mm in diameter to nearly all manufacturers of seamless tubes. The quality and service life of CHINA TIPTOP seamless pipe mandrel bar has won good reputation from home and abroad.
